Prescription, Polarized, and Performance Sunglasses

Sunglasses help protect your eyes from the harmful UV rays from the sun. The most important feature to look for in sunglasses is blocking 100% of UVA and UVB rays. However, there are many other features of sunglasses you can select to meet the needs of your lifestyle. Here is a brief overview of prescription, polarized, and performance sunglasses.

Prescription Sunglasses

All prescription sunglasses purchased from our office protect your eyes from harmful UV rays of the sun and block 100% of UV rays. Prescription sunglasses are an excellent option for both glasses and contact lens wearers in many situations. Try keeping a pair of prescription sunglasses in your car so you are able to remove your glasses and switch to prescription sunglasses easily. These sunglasses will provide you with vision correction, minimized glare, and dimmed the brightness of the sun.

Contact Lens Wearers

Prescription sunglasses are a great solution for contact lens wearers when swimming at the pool or beach. It is not recommended to swim in contact lenses, so prescription sunglasses make an excellent alternative for clear vision during these activities.

Polarized Sunglasses

Polarized sunglasses have always been popular with boaters and fishers to reduce reflected glare from the water. However, others like hikers, bikers, golfers, and joggers also benefit greatly from polarized sunglasses. Polarized sunglasses optimize your vision for safety and performance by eliminating glare caused from light reflected off flat surfaces. Polarized lenses improve comfort and visibility. These lenses are also great for driving because they help reduce glare from the hoods of cars and off the road’s surface.

Performance Sunglasses

The goal of performance sunglasses is to provide you with the best vision possible under all conditions. These glasses are designed to be lightweight, flexible, durable materials, no-slip, and have lens color variations. Performance sunglasses are great for sports such as mountain biking, snowboarding, rock climbing, kayaking, skiing, golfing and in-line skating. While performance sunwear is most often used by athletes, they are also helpful for those who work outdoors, do a lot of driving, or are in the military.

Popular features of performance sunglasses include anti-reflective coating and changeable lenses. The anti-reflective coating applied to back surface of lenses to eliminate glare from light reflecting off the back of lenses when the sun is behind you. Changeable lenses allow you to switch out your lenses for the tint that will best match the lighting conditions for the day.

Selecting the best sunglasses for you is highly dependent on the needs of your lifestyle. Do you need help deciding the best type of sunglasses for your lifestyle? Contact our office we are happy to assist you in your sunglasses selection!

Are online eye tests any good?

Have you considered getting online eye tests? The idea of being able to get an eyeglass prescription and buy glasses without a trip to the eye doctor may sound appealing. Before ditching the traditional eye exams, there are a few things you need to know!

Online Eye Tests

The most important thing to know about online eye tests is they do not evaluate the health of your eyes. Even if they are called “online eye exams,” these exams only measure your visual acuity and refractive error. Some online eye tests can check for contrast sensitivity and color blindness. However, none of this can tell the health of your eyes.

The only way to know the complete health of your eyes is through eye exams with your doctor. During an eye exam, your doctor can detect vision-threatening conditions such as cataracts, glaucoma, or macular degeneration. Early detection of these conditions can prevent vision loss and blindness.

Know The Risks:

  • Online eye exams cannot detect eye diseases
  • Improper testing can occur due to error or misreading instructions
  • Higher chance of getting incorrect prescription due to self-administered the eye test
  • If you think the prescription is incorrect, your only option is to pay again and retake the test
  • An eyecare professional is not present to answer questions or concerns

Validation of Online Eye Tests

The results of online eye tests have not been guaranteed to be accurate measures of your prescription. Due to this being relatively new technology, there have not been enough studies to determine the reliability and validity of online eye tests.

Additionally, many online eye tests say their technology is suitable only for people between the ages 18 and 40 who are in good health. The limitations of the eye test raise concerns to the overall validity of the test. For these reasons, we do not recommend them as your sole option for your receiving your prescription.

The best way to ensure your eyes are healthy, you receive the correct prescription, and get answers to all your questions is through face-to-face eye exams with your eye doctor. Our staff of trained eyecare professionals will help you through every step of the process. Our office is here to address any questions or concerns you may have.

Myths and Facts: Contact Lenses

Are you a contact lens wearer? If so, you’ve probably heard some myths about wearing contact lenses. Typically, these contact lens myths grow from an unusual experience or misunderstanding information. Many contact lens myths are based on the way contact lenses used to be, instead of the current design and technology of contact lenses. We wanted to debunk some of the contact lens myths and give you the facts instead!

1.I’m too old to wear contact lenses

Fact: Anyone, at any age can wear contact lenses. Many older adults choose to wear contact lenses instead of reading glasses.

2. Contact lenses will get lost behind my eye

Fact: It is physically impossible for a contact lens to get lost behind your eye. A membrane covers your eye which connects inside your eyelids to prevent anything from getting behind your eye.

3. Contact lenses are uncomfortable

Fact: Modern contact lenses are thin and soft, making them very comfortable and often unnoticeable to wear. Some of the early contact lenses made 40-50 years ago were uncomfortable. However, we recommend you try modern contact lenses before sticking with this assumption.

4. Contact lenses can get stuck on my eye

Fact: If you follow proper wear, care, and removal advice from your eye doctor your contact lens cannot get stuck to your eye. Should your lens feel dry, apply some rewetting drops, and they should loosen right up.

5. Contact lenses are too much trouble to take care of

Fact: Daily disposable contact lenses make lens care irrelevant. You wear them one day and throw them out when you are done. However, reusable contact lens care is relatively simple with modern solutions. Most contact lenses can be cleaned and stored using one multi-use contact lens solution.

6. I’ll never be able to put in contact lenses

Fact: Our staff will show and teach you how to put in contact lenses. We ensure that you are confident in your abilities to put in and take out your contacts before you leave our office. Most people can figure it out after a handful of tries!

7. Contacts can pop out of my eye

Fact: Properly fitted contact lenses should never pop out of your eye. Typically, the only way a contact lens will move is shifting around your eye. Therefore blinking a few times or closing your eyelid and gently pressing on it should move the lens right back into place.

8. Contact lenses are too expensive

Fact: The cost of contact lenses varies depending on brand, replacement schedule, and how often you wear them. Typically, the price is comparable to a new pair of glasses. Above all our team will help you select contact lenses that work best for your lifestyle and your budget.

9. Children and teenagers cannot wear contacts

Fact: There is no age restriction on wearing contacts. Anyone can wear contact lenses; ultimately it depends on enthusiasm, responsibility, and maturity. Our staff can advise whether contact lenses are a suitable option for your child.

If you have more questions about contact lenses, give our office a call! We want to help you feel confident in your knowledge of contact lenses.

Eye Safety In The Home

Have you thought about eye safety in your home? Over 2.4 million eye injuries each year in the United States. Experts say wearing safety glasses and taking a few common-sense precautions can prevent or reduce the severity of eye injuries.

Common causes of eye injury in the home:

  • Household cleaners and chemicals
    Tip: Keep out of reach of children, high shelves in cupboards or childproof cupboards.
  • Toys and games (hard or sharp edges)
    Tip: Always check the age recommendation to ensure toys are appropriate for your child.
  • Eye makeup and applicators
    Tip: Throw out old or damaged products to avoid potential eye hazards.
  • Lawn, garden, and hand tools
    Tip: Wear protective eyewear when completing house or yard work.
  • Champagne Corks
    Tip: Never face the cork towards anyone’s face, including your own.
  • Fireworks
    Tip: Attend a professional firework show, avoid the risks associated with at home fireworks.

 

What to do in case of eye injury

If you or your child has an eye injury contact your eye doctor immediately. If it is after regular work hours, try an emergency contact number or call 911. It is always better to be over cautious when it comes to your eyes.

The next steps after your phone call vary greatly depending on the eye injury. Typically, we either recommend you come to our office or go to the emergency room. Depending on the situation your eye doctor may also ask you to flush your eye, remove your contact lenses, or cover your eye.

When in doubt treat all eye injuries as potential emergencies. You only have one pair of eyes, and we want to ensure they are taken care of.

What to look for in safety glasses

Safety glasses should be worn when doing any house repairs/renovations, yard work, or sports activities. This is the best way to protect your eyes from potential harm. When looking for safety glasses, it is important to have impact-resistant polycarbonate lenses and safety rated frame.

If you have additional questions about eye safety in the home, ask our staff. We want to help you keep your eyes safe and healthy!

Computer Vision Syndrome: Eye Strain

According to The Vision Council, 65% of adults experience some form of computer vision syndrome. Often individuals associate eye strain as a “normal” part of computer work. However, the eye strain you are experiencing is a symptom of computer vision syndrome and can be reduced or avoided!

What is Computer Vision Syndrome?

Computer vision syndrome is caused by the eyes and brain reacting to the characters on a computer screen. On-screen characters have less contrast than characters in print and are more challenging for our eyes to focus on. The difficulty of having to focus on the characters on computer screens is what causes eye fatigue and strain.

Symptoms of CVS

Depending on the individual they may experience one, several, or all symptoms of computer vision syndrome. These symptoms can cause discomfort for the individual and make it difficult to complete work effectively.

  • Headaches
  • Loss of focus
  • Burning eyes
  • Tired eyes
  • Red eyes
  • Double vision
  • Eye twitching
  • Blurred vision
  • Neck and shoulder pain

Ways to Combat CVS

Many computer users find their eyes feel strained working under fluorescent lights. Users feel more eye comfort when using floor lamps instead of harsh overhead lights. Minimize the reflection of glare off your computer screen by installing an anti-glare screen on your monitor. Consider closing the blinds to prevent the sun from reflecting off your computer screen as well.

The type of screen and settings of your screen can also impact your eye strain. We recommend making sure you have an LCD screen because it has an anti-reflective surface and is more comfortable for the eyes.

Additionally, you can adjust the settings of your screen for optimal viewing. A few settings to adjust are the brightness, text, and color temperature. The brightness should be the same as your surrounding workstation, the text size and contrast can be changed to your comfort level, and reducing the color temperature lowers the amount of blue light emitted by your screen.

Computer Eyewear

One of the best ways to reduce your risk of computer vision syndrome is to visit our office. Your eye doctor can perform a few tests to detect vision problems which could be contributing to your computer vision syndrome and help decide if computer eyewear is the solution for you. Many individuals discover computer eyewear helps reduce their symptoms and improves their productivity.

Schedule an appointment with our office to discuss the impact computer work is having on your eyes and the best ways to reduce your eye strain and fatigue.

 

Perfect Glasses For Your Lifestyle

We believe that your glasses should complement your lifestyle and meet your vision needs! With everyone having different priorities, jobs, and activities in their life eyewear is not a one size fits all. We want to help you select the perfect glasses for your lifestyle!

Business Eyewear

The savvy business professional wants glasses that enhance their professional image. Your appearance can influence clients and colleagues initial impression of you. Therefore, we recommend eyewear that will instill trust and confidence in you. Typically, this includes a more conservative frame shape and color. Silver, gunmetal, gold, black, brown, and burgundy are popular options to wear and match with business attire.

Creativity and Fashion Glasses

The fashionista is looking to showcase their style and taste in every accessory they wear. Glasses are one accessory you wear every day and need to match with every outfit. Showcasing style in your glasses can easily be done through unique frame shapes, bright colored frames, or patterned frames. A significant fashion trend lately is retro or vintage styling!

Active and Sport Eyewear

When your lifestyle is revolved around sports and active living, you need eyewear that can handle any activity. As a result, your sports performance may benefit from sports sunglasses, sports eyeglasses, or protective sports eyewear! Optimize your performance with sports eyewear designed to meet your sports needs best. Standard features in sports eyewear include polarized lenses, polycarbonate lenses, and lens tints.

Frame Allergies

Always inform your eye doctor of any allergies you have to materials in frames or nose pads. Common frame allergies include metal allergies like nickel. As a result, we offer a wide variety of metal and plastic frames our opticians will help you select a pair you can wear. Some patients also have an allergy to silicone nose pads. For that reason, our opticians are familiar with non-silicone nose pad options. We want to ensure you can wear your glasses every day without an allergic reaction.

Computer Worker

Does your job require long hours spent on a computer? As your average computer time per day increases your risk for developing eye strain and computer vision syndrome increases as well. Computer glasses are designed to optimize vision at the intermediate distance and eliminate digital eye strain symptoms. Additionally, the lenses in computer eyewear protect your eyes against the harmful blue light.

Driving Glasses

Studies have shown glare to be a factor in automobile accidents. Sun shining in your eyes and glare reflecting off the road can make it difficult to see other cars or pedestrians. Driving glasses can be either polarized plano sunglasses or prescription eyewear. Polarized sunglasses reduce glare from the sun and increase contrast for sharper vision while driving. Prescription glasses with an anti-reflective coating minimize glare from light and better vision during nighttime driving.

Safety Eyewear

Protect your eyes by wearing safety glasses, sports goggles, or shooting glasses. Safety eyewear is durable, provides more coverage, and is impact resistant. Certain occupations require safety eyewear because they work in hazardous conditions. However, when completing home renovations or repairs, you can also face eye dangers. Always wear safety eyewear when completing any task that includes dust, flying shards, chemicals, or UV radiation.

Screen Time and Children

Screen time is the amount of time a person spends staring at digital displays including computers, tablets, smartphones, and TVs. In our modern and technology-focused world children are spending time on digital displays for educational and recreational purposes. Children who spend several hours on digital devices are at risk of developing vision-related problems.

Average Time Children Spend On Digital Devices

According to the Vision Council, 72% of American parents report their children regularly spend more than two hours on screens per day. It is likely that children spend significantly more time on screens than their parents think. Common Sense Media reports that children under age eight spend more than two hours a day with screen media. For 8 to 10-year-olds screen time triples to six hours per day. Kids in middle school and high school spend up to nine hours per day looking at digital displays.

Risks of Screen Time

Too much screen time can be dangerous for anyone’s eyes, children included. Screens emit a broad spectrum of visible light. While most of these light rays are harmless, blue light is a high-energy visible light that can cause damage to your eyes. Blue light has shorter wavelengths and higher energy causing harm to the retina over time. Overexposure to blue light can cause:

  • Difficulty sleeping
  • Headaches
  • Neck/shoulder pain
  • Eye strain
  • Reduced attention span
  • Poor behavior
  • Irritability

Computer Vision Syndrome

Computer vision syndrome is a condition caused by visual stress. Symptoms include tired eyes, dry eyes, headache, and fatigue.

Unhealthy Posture

Your body naturally slouches inwards when on digital devices. Your back and shoulders round, your head tilts back, and your chin justs forward. This reaction to digital devices is called “turtling” and can cause neck, back, and shoulder pain.

How To Protect Your Child’s Eyes

It is clear digital devices will not be going away anytime soon. Therefore it is essential to ensure you are doing everything you can to protect your children’s eyes from digital screens. One way you can do this is by limiting screen time for your children while at home. You can also apply blue light filters or download blue light filtering apps to all digital devices. If your child wears prescription glasses, ask us about add blue light blocking to their lenses during your next appointment.

Nighttime Use

The largest source of blue light is our sun, which tells our brain when to be awake or sleep. The high use of digital devices emitting blue light may disrupt your natural circadian rhythm (sleep cycle) by miscommunicating the time of day and if you should be awake or asleep. Stop digital device time two hours before usual bedtime to ensure your child’s sleep schedule affected by blue light.

Do you have more questions about screen time and blue light? Stop by our office or give our office a call and we would be happy to answer your questions!

Why You Need Multiple Pairs

Thanks to our busy lives, multiple hobbies, and all the activities in between, having multiple pairs of eyewear handy is a necessity. Even contact lens wearers should have alternative pairs of eyewear. But some of us still haven’t jumped on that bandwagon. If you’re still on the fence, here are a few reasons why it’s a great idea to have at least two pairs of eyewear:

Misplacement

We’ve all been there, searching for missing glasses just when we need them the most. An additional pair of eyewear can’t guarantee they won’t keep slipping through the cracks, but it will significantly reduce the chances of having to go without. Lost a contact lens and don’t have a replacement? Backup glasses can hold you over until your new contact lenses come in!

Style

Think about it: a night out on the town is going to call for more stylish eyewear than the amber-tinted lenses you wear at your computer desk. Funky frames may better showcase your personality, but a more neutral pair may be needed for professional situations. Having different styles of glasses removes this dilemma by giving you situation-specific options.

Protection

Chances are, your standard glasses aren’t going to adapt and darken in reaction to sunlight (unless you have photochromic lenses), so it only makes sense to invest in a pair of prescription sunglasses to protect your eyes. Polarized lenses are a good option, especially since the tint can be tailored to your specific sport or hobby.

Contact Lens Wearers

Plano sunwear is a must have for all contact lens users. Contact lenses do not protect your eyes from the harmful UV rays of the sun. We recommend plano sunwear that blocks 100% of UV rays for anyone who wears contacts.

Schedule an appointment with our office if you’re interested in investing in a second pair of glasses! We will help you find the best frames and lenses for your lifestyle!

Know the Facts About Cataracts

Did you know, cataracts are the leading cause of blindness in the world? Cataracts affect nearly 20.5 million Americans age 40 and older.* If you are over the age of 50, you should have a yearly comprehensive eye exam to detect cataracts as they develop.

A cataract is the clouding of the lens in your eye. Many people describe the feeling as if you are looking through a foggy or frosted window.

What causes cataracts?

Clouding of the natural lens in your eye is caused by proteins clumping together within the lens. It is unknown why the eye changes as the body ages, but these changes may cause cataracts to grow larger over time, resulting in an increased difficulty to see clearly.

Some factors that have been linked to cataract development are diabetes, obesity, smoking, ultraviolet radiation, and family history.

Symptoms

Symptoms associated with cataracts can vary from person to person. However, there are a few key symptoms associated with most cases of cataract development. If you are experiencing one or more of these symptoms, schedule a visit with your eye doctor to discuss your risk or development of cataracts.

  • Slight blur in vision
  • Vision is cloudy
  • Sunlight or lamps feel too bright
  • Headlights have more glare and/or a halo around them
  • Colors no longer appear as bright as they once did

Types of cataracts

Subcapsular

Subcapsular cataracts typically occur in the back of the lens and are most common in individuals with diabetes or those taking a high dose of steroid medication.

Nuclear

Nuclear cataracts are associated with aging and occur in the central zone of the lens.

Cortical

Cortical cataracts occur in the lens cortex and are associated with streaks which interfere with light passage through the eye.

Congenital

Congenital cataracts are present at birth and may be due to genetics or intrauterine infection.

Are cataracts preventable?

No studies have shown a way to prevent cataracts, however, there are recommended practices to help maintain eye health and lower your risk of developing cataracts.

  • Yearly comprehensive eye exams help maintain eye health and detect the development of cataracts at an early stage.
  • Smoking has been linked to the development of cataracts. Quitting smoking provides a variety of health benefits lowering your risk for further cataract development.
  • Keeping up with treatment if you have diabetes or other medical conditions will help minimize your risk.
  • Maintaining a healthy diet, including fruits and vegetables, provides increased overall eye health.
  • Wearing sunglasses to prevent ultraviolet radiation will decrease your risk of UV damage which has been linked to the development of cataracts.

How to Read Your Prescription

Have you ever received your prescription at the end of your exam but were unsure how to interpret it? Below are some common questions and terms explained to help you better understand what each part of your prescription means. If you have any questions about your prescription, please reach out to our office.

What does it mean to be nearsighted?

Nearsightedness (myopia) is the most commonly diagnosed refractive error. Nearsighted individuals have difficulty reading road signs and clearly seeing distant objects. This refractive error typically begins in childhood and stabilizes in early adulthood. Symptoms of myopia include squinting, eye strain, and headaches.

What does it mean to be farsighted?

Farsightedness (hyperopia) affects about one-fourth of the population.* Farsighted individuals will have difficulty focusing on objects up close but can clearly see objects at a distance. The eye shape of someone who is farsighted is shorter than normal. For this reason, many children are born farsighted and outgrow it as their eyeball grows.

I have astigmatism, what does that mean?

Individuals with astigmatism usually experience some degree of blur or distortion at all distances. In astigmatism, light comes into the retina at multiple focus points because of an irregular shaped cornea, which causes blurring. With astigmatism, one or both eyes can be farsighted, one or both eyes can be nearsighted, or one eye can be nearsighted while the other is farsighted.

Reading the Prescription

Your prescription is an outline of corrections your eyes need in order to see as precisely as possible. Every prescription will look different based on the patient’s eyes. If you have questions or do not understand a section of your exam or prescription, be sure to ask your doctor.

OD and OS

Doctors use the abbreviations OD, OS, and OU when writing a prescription for eyeglasses, contact lenses, and eye medicines. OD and OS are abbreviations for the latin words oculus dexter (right eye) and oculus sinister (left eye). The latin term oculus uterque is used for describing both eyes.

Other terms on your prescription:

  • Sphere (SPH): Indicates the lens power needed to correct nearsightedness or farsightedness. If you have a minus sign (-) you are nearsighted; if you have a plus sign (+) or no sign you are farsighted.
  • Cylinder (CYL): Indicates the amount of lens power for astigmatism. If nothing appears in this column you do not have astigmatism. The minus sign is for nearsighted astigmatism and a plus sign for farsighted astigmatism.
  • Axis: Indicates the direction of astigmatism. For example, if the axis is 180 degrees the astigmatism is horizontal.
  • Add: Indicates the magnifying power applied to the bottom of multifocal lenses to correct presbyopia. The number is typically a plus power and will be the same for both eyes.
  • Prism: This is to compensate for eye alignment problems, a very small percentage of prescriptions contain a prismatic power. Abbreviations used for prism direction: BU- base up, BD- base down, BI- base in, BO- base out.
