Frequently Asked Questions About Vision

Good vision is the most essential sense we have. In fact, we perceive over 80% of our impressions through sight. From finding new friends, to staying far away from spoiled food, our eyes both enhance our lives and keep us safe. It’s only natural to have questions about our eyes, and how to keep them healthy. Unfortunately, there are also many misconceptions about the eyes out there. Read on for the answers to some of the most common questions about vision.

Can eyes be transplanted?

Unfortunately, whole eye transplants are not possible – yet. Scientists think they may be able to complete the complex procedure within the next decade. For now, doctors have to settle for only partial eye transplants, including corneal transplants

Can electronic screens hurt my eyes?

Electronic screens alone cannot hurt your eyes. However, the blue light emitted from electronic screens can cause eye strain or dry eye. This can lead to other harmful effects like headaches. You can prevent this strain by wearing glasses with 39DollarGlasses’ Blue 495 anti-glare coating

How often do I need to get my eyes checked?

Children older than 6 months should get their eyes checked every year. Adults ages 18 through 60 should get their eyes checked every 2 years, or as soon as they notice a decline in their vision. For older adults age 60 and above, yearly checkups are essential.

Will reading in dim light hurt my eyes?

Reading in dim light will not damage your vision; however, it can lead to dry eye. When you read in insufficient light, you naturally blink less often. This is your body’s way of trying to adjust to the light. The less you blink, the less lubricated your eyes will be. When in doubt, it is beneficial to use a reading light.

If I cross my eyes, will they get stuck like that?

Contrary to your mother’s constant nagging, your eyes will not get stuck in that dreadful position if you cross them. However, crossing your eyes for long periods of time will cause some serious pain. Your eyeballs have six muscles that help them move around. Since you don’t go cross-eyed often, your muscles aren’t used to working that way. When you cross your eyes for long periods of time, your muscles become exhausted. This muscle strain can lead to headaches.

Is poor vision hereditary?

Although you can blame your hair and eye color on your parents, they aren’t responsible for all your eye problems. Some vision problems are genetic. The “standard” eye problems we often think of are linked to our genes – such as nearsightedness, farsightedness, and colorblindness.

However, some eye problems have various causes. For example, glaucoma is caused by a fluid build-up in the eye that damages your optic nerve. Similarly, amblyopia, also known as lazy eye, is caused by under-development of the eye.

What are the “spots (floaters)” floating around in my eye?

If you’re seeing spots there is no need to panic. These floaters are very common, especially the older you get. Most of your eyeball is filled with a gel-like material called vitreous. This gel acts as a shock absorber for the retina at the back of your eye. As you age, this material starts to weaken. As it breaks down, parts of the gel peel off and float around inside your eye cavity. They cast shadows on your retina, which causes the “spots.”

While these spots generally aren’t a concern, an abundance of floaters could point to a more serious issue. Floaters can be a warning sign of retinal detachment, which causes permanent vision loss and must be repaired with surgery. Similarly, if you see a sudden increase of floaters paired with flashes of light, you should contact your optometrist right away.

What does “20/20 vision” mean?

The term “20/20 vision” is used to express your clarity of vision measured from 20 feet away. If you have 20/20 vision, that means you can see clearly at 20 feet. However, having 20/20 vision does not mean you have perfect vision. Other important vision skills, like side vision and depth perception, contribute to your vision’s overall acuteness.

In fact, some people have well over 20/20 vision. If you can see clearly 50 feet away, you have 20/50 vision.

If your vision is under 20/20, 39DollarGlasses has you covered. We offer a wide range of unique frames with discounted prescription lenses. Our glasses allow you to show off your personality, without breaking your budget. You can get glasses for the whole family – including toddlers and children.
