The Importance of Corrective Lenses & The Benefits of Visiting Your Ophthalmologist
A momentary blur in your vision is one of life’s more annoying experiences, but you may not realize that it’s actually a sign that you need a pair of corrective lenses. Many people choose to purchase eyeglasses because they’re fairly inexpensive and they’re able to correct their vision immediately. However, many optometrists are also able to prescribe you with contact lenses that correct your vision even further than glasses.
If you’ve never been prescribed contacts before, you may be wondering why you need them. We’re here to explain the importance of corrective lenses, how to choose the best ones and the benefits of visiting your optometrist.
What Is A Corrective Lens
People with vision deficiencies often wear corrective lenses. These are different from sunglasses that only increase the amount of visible light entering your eyes.
A corrective lens is a small, flexible plastic or glass device that blocks harmful rays of light from entering your eyes. The most common types of lenses are an ultraviolet (uv) filter, blue light filter, and green light filter.
Why Do You Need Corrective Lenses
While sunglasses are super fun and a great way to protect your eyes from harmful ultraviolet rays, they do not correct your vision. In fact, sunglasses can actually make the problem worse because they absorb the same amount of light that you need to see.
That’s why most people who wear sunglasses have some degree of vision loss. Plus, sunglasses are not that great at blocking out the sun’s glare and/or other harmful light rays.
One of the most common reasons people visit an optometrist is to get a pair of glasses or contacts that correct their vision correctly.
You may also need to see an optometrist to figure out why you’re experiencing blurred vision. This could be an issue with your eyes, your eyesight or with the way you’re holding your head.
How Do Corrective Lenses Work
When we look at a normal object, light rays from the object enter our eyes and travel through the retinal nerve to the brain. But if you’re nearsighted or if your eyes are otherwise diseased, the light rays aren’t directed correctly. The brain is confused, and you see a blurred image.
Corrective lenses work by directing the light rays through a “slit” or “fence” to the part of the brain that sees clearly. By wearing corrective lenses, you correct your nearsightedness or other vision problems that affect your eyesight. And by using glasses, you’re able to see more clearly than you would without corrective lenses.
The Benefits Of Corrective Lenses
- Better Eyesight - We’re sure you’ve heard this one before, but it’s true. Wearing glasses or contacts can actually improve your eyesight. It may seem weird that wearing a piece of plastic could help your vision, but it does.
- Better Vision - Our eyes are constantly absorbing information from the world around us. If you’re nearsighted, the part of your retina that normally absorbs the most light is blurred. That’s why you see a blurry image when you wear sunglasses.
- Better Eyes - Wearing glasses or contacts can also affect the health of your eyes. Continuous exposure to harmful light rays can result in dry eyes, macular degeneration (a condition that causes blurry spots in the center of your vision), cataracts, and glaucoma.
