How to Find Your Dominant Eye

Do you know your dominant eye? Is it even possible to have a dominant eye? We are sure you have heard the term ‘dominant eye’ but you might not be sure what it means. Please allow me to explain.

What is a dominant eye?

Simply put, your dominant eye is the one that provides more input to the visual part of the brain and relays information more accurately, especially with regard to the location of objects.

Sometimes the dominant eye is used to describe the normally functioning eye in cases where the other is weaker such as with strabismus (eye turns) and amblyopia (lazy eye).

How to do a Dominant Eye Test

Here is a simple test to determine your dominant eye.

  • Create a small triangular opening between your thumbs and forefingers to form 45 degrees by placing your hands together as shown below.

  • With both eyes open, center triangle on an object at some distance from you-such as a door knob.

  • Close your right eye.

  • If the object remains centered, then the open eye (the left one) is your dominant eye. If the object moves, then your right eye is the dominant eye.

Is Eye Dominance Directly Related to Handedness?

Studies have shown that being right-handed/left-handed is not directly related to eye dominance but with both the right side tends to be the dominant

Research shows that around 90% of the human population are right handed and 67% are right-eye dominant.

While it is correct to say that a right-handed person is 2.5 times more likely to be right-eye dominant, it’s still impossible to determine eye dominance based on your dominant hand.

No Dominant Eye: Is It Possible?

It’s nearly impossible to not have a dominant eye but there are a few specific cases.

If an individual lacks a dominant eye, it’s more likely that the person has a mixed ocular dominance (alternating ocular dominance), where one eye is dominant for certain tasks and the other eye is dominant at different times.

Fact: Knowing your dominant eye will help you in photography and in sports like golf and baseball.

Choosing The Best Lenses For Your Glasses

image1.jpg

When shopping for eyewear, to maximize your own comfort and convenience —and to make the most of your investment— it’s important to choose the best lenses for your glasses.

Brands and your own prescription are some things to consider if you’re trying to choose the best lenses.

For eyeglasses, choosing the right type of lenses can be quite challenging. We all want to look good in our glasses while at the same time, prioritizing comfort without compromising vision and visual acuity.

Since the market is saturated with so many choices of lenses and coatings, we decided to make this guide for you to have an easy time selecting the best quality lenses for glasses.

But, before we begin, why is choosing the right lenses so important?

When you’re buying glasses, the most apparent factor affecting your appearance and comfort is your frame selection. However, you should not neglect your decision of lenses; the type of lenses you opt for for your eyeglasses often has plays a large role in your overall vision quality, comfort, safety, and even your appearance.

So, when deciding which type of lenses, you should consider how a given lens type will affect these four factors: comfort, appearance, vision, and safety.

The common mistake that people make when buying eyeglasses is not spending enough time to consider their eyeglass lens coatings, materials, and designs.

This guide will equip you with the basics you need to know to purchase any type of prescription eyeglasses wisely.

1. Eyeglass Lens Material

When choosing your lens material there are a number of options to consider, each of which offers its own benefits and drawbacks; some are more affordable or more durable than others, while newer types of lens materials can offer all that with added vision quality but at a higher price point.

Here are some options for you to consider:

Plastic Lenses

Plastic lenses made with CR-39 polymer (short for Columbia Resin 39) are the most common type of glasses lenses in use today, unlike glass lenses —which are rare these days— plastic lenses are lightweight, affordable, and durable, without sacrificing vision quality.

Polycarbonate Lenses

Developed by Gentex Corporation in the 1970s, polycarbonate lenses were originally designed for use in safety glasses, helmet visors, and “bulletproof” glass; they are significantly lighter and more impact resistant than plastic lenses.

Since then, polycarbonate lenses have became increasingly popular for a variety of different types of glasses, including children’s and sports eyewear, but you might not get the most out of them if you’re shopping for the best lenses for reading glasses.

Trivex

The best lenses for prescription glasses are made with a material called Trivex, which have even higher abbe values than polycarbonate lenses.

Trivex was introduced by PPG Industries in 2001, and it was designed as a rival lens material to polycarbonate lenses. Like polycarbonate lenses, lenses made of Trivex are thin, lightweight and much more impact-resistant than regular plastic or glass lenses.

Here are some of the features of trivex-made lenses.

  • Superior impact- and scratch-resistance

  • It is the lightest material available as of now

  • Has a higher abbe value than other materials like polycarbonate

  • Blocks 100% of UV light

2. Index of Refraction

Also known as the refractive index, this is the relative measure of how a material bends (refracts) light, and this affects the thickness of the lenses for any given frame.

Depending on your prescription, you may or may not need the best high index lenses.

For glasses, thinner lenses typically have a higher refractive index, while thicker lenses usually have a lower refractive index.

3. Abbe Value

image3.jpg

A lens material’s abbe value is the measure of how widely it disperses various wavelengths of light as it passes through the lens.

Normally, when you wear eyeglasses with lenses with a low abbe value, you’ll notice chromatic aberrations —optical errors that can be seen as colored halos around objects such as headlights. Chromatic aberrations are the result of high dispersion of light.

For better vision, we recommend lenses with a higher abbe value to filter out unwanted aberrations.

4. Lens Design

There are many lens designs out there, but if you want eyeglasses that are going to meet your everyday needs, we highly recommend Shamir digital lenses.

Shamir’s Autograph II Single Vision is a digital RX prescription lens for everyday use, while thier Autograph III is one of the best lens for progressive glasses, simulating real world images with a phenomenal field of view.

5. Lens Coatings and Treatments

image2.jpg

Depending on how you plan to use your glasses, there are a variety of lens treatments and coatings for you to choose from.

For example: for blocking harmful UV rays and blue light, we treat our patient’s lenses with Crizal Prevencia.

Crizal Prevencia blocks out all these harmful rays while allowing in the good light that boosts brain activity and regulates mood and sleep.

If you use computers for more than six hours a day, we highly recommend you get your glasses treated with the Crizal Prevencia coating.

For a more precise vision, we use anti-glare coatings like Avance and Sapphire to block unwanted reflections.

These coatings cut out the glare in our everyday life surroundings to reduce eye strain. The coatings also contain UV protection without the appearance of colored hues on the eyeglass lenses.

 

 

The different materials and coatings we’ve listed in this post are optimal for your everyday use.

If you’re looking for the best place to buy lenses for glasses, whether lenses for reading or prescription eyeglasses, you can visit Midtown Optometry.

At Midtown Optometry, we are always more than happy to meet with you and discuss about your ideal lenses.

How to Keep Your Eyes Healthy and Strong —6 Good Eye Health Tips

Good eye health habits are very important for keeping healthy eyes.

If you want to start maintaining good eye health, there are certain habits that you need to adopt.

It’s not that difficult to adopt these habits, and in the end, they’ll help you keep your eyes healthy as you age. Here are simple steps that you can take to ensure that your vision is at its best.

1. Practice Good Eye Health Nutrition

Some of the best foods for eye health

Your vision’s health is highly determined by what you eat. Your diet has a powerful influence on your eye health.

Certain nutrients: lutein, omega-3 fatty acids, zinc,  vitamin C, and Vitamin E, protect you from age-related eye diseases like cataracts and macular degeneration, helping to preserve healthy eyes into old age. These are the best eye health vitamins and the best foods for eye health will be rich in these; to get enough of  these nutrients and vitamins, ensure that you eat the following foods at least once every day.

  • Tuna, salmon, and any other oily fish

  • Oranges, citrus fruits and any other juicy fruits

  • Green leafy vegetables like kales, spinach and collards

  • Eggs, beans, nuts and other non-meat protein sources

2. Wear Sunglasses to Block UV Rays

Too much UV exposure causes cataracts and macular degeneration, and overexposure to UV light is never good for eye health.

To minimize the amount of UV light entering your eyes during the day, be sure to pick the right pair of glasses. If you’re buying shades, be sure that you buy shades that block 99% to 100% of UVB and UVA rays.

If you are always on the road, polarized lenses are your best choice for reducing glare; grey lenses are a good choice —they preserve your color perception which helps you process visual stimuli more quickly. We recommend you get wraparound sunglasses to protect your eyes from the side.

Even if you wear contact lenses that offer UV protection, it’s vital to wear sunglasses for extra protection.

3. Use Computer Glasses

If you stare into a computer screen for too long, you’ll experience several negative health effects: blurry vision, eyestrain, dry eyes, headaches, and trouble focusing at a distance.

To protect your eyes from overexposure to computer light, here are some tips on how to maintain good eye health in the post-modern era.

  • Get glasses for computer use and get an anti-glare screen

  • Blink more often if your eyes dry off

  • Ensure that the lighting in your work area is as bright as your computer screen

  • Rest your eyes after every 20 minutes by looking away for 20 seconds

4. Use Safety Wear

If you work in an environment that can potentially hurt your vision, use safety goggles to protect yourself from hazardous and airborne debris. Preventing physical injury is even more important than proper eye health nutrition.

Don’t let an unfortunate accident destroy a lifetime of good eye health; no one wants to lose an eye.

5. Quit Smoking

Did you know that smoking can damage your optic nerve and cause macular degeneration?

If you’ve been trying to quit smoking, ensure that you completely quit smoking.

Studies show that the smoke smokers exhale can potentially induce cataracts. Apart from eye related problems, smoking also causes many other medical problems.

6. Visit your Eye Doctor Regularly

We all know prevention is better than cure. Visiting your eye doctor on a regular basis will ensure that your vision is always at its best.

Additionally, visiting your optometrist regularly will allow for early detection and prevention of many eye diseases that can threaten your sight.

When did you last visit an optometrist? We are always happy to help new patients. Whether it’s your first time with us or you’re coming in for your annual check-up, schedule an appointment with us hassle-free online.

 

 

Now that you know what to do to keep your vision on check, share this short guide with your friends and family to keep more eyes healthy.

Does Exercise Improve Eye Health?

various people doing cardio.jpg

Living in Santa Cruz, many of us are excited about fitness. From world class mountain biking, to breathtaking hiking and big wave surfing, we live in a Mecca for the outdoors. What many of you might not know, however is that exercise is also important for your eye health.

The fact is that exercise is good for you, this much is common knowledge --whether for getting into shape, keeping generally fit, and even improving your mental well-being. What you might not know, though, is that exercising just a few times a week can help preserve your vision and decrease your risk of developing eye diseases.

High blood pressure and high cholesterol can potentiate vision problems and eye disease.

Two of the most essential steps to preserving your vision are maintaining a healthy diet and exercising regularly; the right kind of physical exertion can be highly beneficial for your eye health.

Studies Indicate a Looming Health Crisis

Multiple studies done over the past decade have revealed a relationship between the lack of exercise and an increased risk of several common eye diseases including wet age-related macular degeneration and diabetic retinopathy.

When left unaddressed, diabetes can damage the retina’s blood vessels and lead to blindness.

elderly people exercising.jpg

The prevailing research predicts that, as today’s population gets older, the proportion of individuals suffering from some form of visual impairment or blindness will double by 2050 — and these numbers are already rising globally.

Regular screening for eye diseases can help combat this problem.

A study which monitored some 4,000 older adults over a 15 year period found that those who kept an active lifestyle and exercised at least thrice weekly had a decreased risk of developing exudative (wet) AMD or macular degeneration.

Wet AMD develops when unwanted blood vessels grow beneath the center of the retina. Blood vessels here can leak blood and fluid into the eye, leading to loss of vision.

Glaucoma affects the optic nerves in the eyes and causes them to not function properly.

The optic nerve transmits visual images from your eyes to your brain and when the this is damaged it can cause a host of vision problems ranging from peripheral vision loss to blindness.

The optic nerve can become damaged in a number of ways such as lack of blood flow, deteriorating effects of diabetes, arteriosclerosis, and glaucoma.

Engaging in cardio exercises increases the blood flow to your retina and optic nerve.

Further, research focused on young adults found that moderate intensity, low-impact exercise leads to a significant reduction in eye pressure; excessively high eye pressure can lead to glaucoma.

The Glaucoma Research Foundation recommends regular, ongoing exercise, such as walking or jogging, to help reduce eye pressure.

In particular, cardiovascular exercises, like aerobics, have been linked to lowered intraocular pressure —the pressure inside your eyes— which is important to the protection of your retinal ganglion cells.

Go Outside, Enjoy Your Exercise

Getting the vision and eye health benefits of cardio workouts is a simple as taking a 20-minute brisk walk four times a week. Brisk walking for just this much every week can increase your blood flow by up to 25%.

If you prefer other exercises to walking, consider other workouts to improve your circulation, like cycling, swimming, dancing, or Pilates; beyond these you have so many other options, including any sports that you may already participate in.

Whichever activity you choose, you’ll not only benefit from improved eyesight and eye health, but a stronger, healthier heart, too.

The cumulative result of these effects is an improvement in general eye health and vision acuity; the beneficial effects are even more pronounced in people suffering from glaucoma.

While exercising, you should make certain that you protect your eyes with proper eye wear to prevent damaging your eyes while you work to improve them; to understand what kinds of eye wear you should wear for different activities, you should schedule a consultation with a sports vision specialist.

What Else Can You Do For Your Eyes?

Be sure that you’re visiting your eye doctor regularly; work with them to schedule checkups at least every year, or every other year at the most, and make sure you have the right prescription for your eye wear.

With all this talk of exercise, it’s important not to neglect the benefits of simply eating healthy. A balanced, nutritious diet is one of the best things you can do for your overall health, but it’s also one of the best things you can do for your eye health.

Be sure to pack your diet with a variety of fruits, vegetables, lean proteins and fish, to give your eyes every advantage.

Healthy Diet.jpg

In addition, cutting down on saturated fats and sugars, protecting your eyes from the sun when you’re outside, even on cloudy days, and quitting smoking, all contribute to protecting your eyes and vision health.

Make exercise, even only light exercise, your priority. This is particularly important, given recent research that shows regular exercise is associated with decreased risks for certain eye diseases.

Study after study has found powerful benefits of exercise from improved mental health to reduced risks of diseases, and even cancer.

With all this, it’s obvious that staying active, getting plenty of exercise, and eating healthily come with many benefits, from general health to improved eye health and preventing eye disease.

Many of us overlook our eyes and vision when we consider what we can do to improve our health; just because we can’t see our eyes, doesn’t mean they are any less important to keep healthy as our hearts, lungs, and minds.

Sunglasses For Kids: Prescription Glasses for Preserving Your Child's Best Vision

Baby wearing sunglasses and sunhat

Since children spend a lot more time outdoors than adults, nearly half of a person’s UV exposure occurs by age 18.

This is why opticians advise that kids need to wear sunglasses when going outdoors…

Sunrays can potentially harm a child’s light-sensitive retina at the back of the eye since the lens inside their retinas are less capable of blocking UV rays than those of adults.

According to a research study on ultra-violet radiation and blue light from sunlight shows that we risk getting multiple age-related eye problems when our eyes are exposed to these sunrays.

When you invest in high quality sunglasses for your kids, you’re helping your kids to have healthy eyes for the rest of their lives.

Are you ready to be a great parent?

Let’s talk about some of the most crucial things that you need to look for in sunglasses for your little one.

Be Sure Your Child’s Sunglasses are Dark

Sunglasses are supposed to block all of the UV light from the sun at all times.

When you are buying sunglasses for your child, ensure that you can’t see their cute eyes when they are wearing the glasses. They are supposed to be completely dark.

Opt for Spring Hinges

Kids are always moving up and down. To properly secure their sunglasses, you should buy them glasses that are fitted with spring hinges to hold the glasses in place.

Impact-Resistant Sunglasses

Sunglasses for young ones should be robust enough to handle their environment.

Polycarbonate sunglasses are the best choice because of their tough and light nature that makes them the absolute best choice for our care-free angels.

Get Them Large Close-fitting Frames

To protect the eyes from UV rays and debris from the environment, it’s important to get sunglasses that are relatively large to cover up your child’s eyes. Sunglasses with wrap around features are good since they stop rays from coming in the sides of the frames.

Younger Children May Need to Use Elastic Bands

An elastic band that extends from one end of the sunglasses to the other guarantees that your young one is well protected from harmful rays at all times.

These bands should be soft and comfortable for the kids to wear and to easily slide them on and off with much ease.

Look for the AOA Sticker

There are a lot of copy cats nowadays and it’s good to always ensure that the sunglasses you’re buying for your little one have the American Optometric Association's Seal of Acceptance.

Gray is Better

Grey sunglasses process all the colors equally so your child will be able to enjoy the world in all its colors and glory.


Researchers have found that the more we are exposed to these harmful UV and blue light (together classified as high energy visible or HEV light) sunrays, the more we risk contracting age-related eye conditions.

Experts say that nearly all high-energy blue light reaches the retinas of adults and children since the human eye cannot absorb these rays. These rays destroy the photosensitive part of the retina, causing eye problems.

Due to these factors, it’s vital to start protecting your child’s eyes from an early age. Even in cloudy and overcast days, you need to ensure that your children are wearing sunglasses because these rays can easily penetrate the clouds.

Armed with these tips, you can now shop comfortably, knowing that you are getting your little one the best sunglasses for their protection.

Now that you are ready to shop, do you know where can you buy authentic and accredited sunglasses for your little one?

An optical shop that cares for your family is a sure way to get the best sunglasses at a friendly price.

So, get your toddler and head over to our store and get ready to take on the sun, sand, and all the other outdoor activities with confidence.
