I wear glasses, and I noticed after I started wearing them that what I could see before without glasses wasn’t as clear as it used to be.
I was convinced that my glasses were making my eyesight worse. I’m not alone either; 64% of Nigerian of undergraduates believed that glasses were harmful for eyesight. In Pakistan, it was 69%. Even some doctors believe that glasses aren’t doing your eyes any good.
However there isn’t any scientific proof that glasses make your eyesight worse.
I Can Swear I Could See Better Before I Got Glasses
What I noticed in my eyesight after I started wearing my glasses was only because my glasses were working to correct my vision. They were allowing my eye muscles to relax and function properly. Without my glasses, I was straining my eyes to focus without the help of this vision correction.
It’s like staying in the dark for a few minutes; your eyes start to adjust. If you turn the light on then turn it off, it will take awhile before you can see in the dark again.
Your vision might have gotten worse after you started wearing glasses; not because of the vision correction but because of aging.
As people get older, their eye lenses stiffen and it becomes harder to focus. Around the age 40 or 50, people start to notice it is harder to read the newspaper or a restaurant menu.
Two Causes For Glasses
Short-sightedness or myopia is when you aren’t able to see far things clearly. It is when the image of what you see is created in front of the retina, instead of on the retina itself.
Farsightedness or hyperopia is the opposite, i.e the inability to see near things clearly. The image is formed behind the retina.
It is surprising how little studies have been done on the long-term effects of wearing glasses for a long time. Most of those that have been done are on children.
If you’re an adult, your eyesight isn’t getting worse because of your glasses and if you choose not to wear them, that also won’t affect your eyesight, unless you are wearing glasses too strong. If your glasses are too strong, your eyesight will definitely get worse, especially if you are near-sighted.
For children, it’s a different story. Children who don’t wear their prescription glasses won’t be able to develop normal vision. If not corrected by the age of 12, it could be permanent and they will develop a lazy eye.
It used to be thought that having children wear glasses that left them a bit near-sighted would slow the progression of near-sightedness. A study in Malaysia found that wearing those glasses actually made the problem worse.
Glasses don’t make your eyesight worse, unless you’re wearing the wrong ones.
You Can Slow The Progression Of Near-sightedness
Recent studies have shown a link between the amount of sunlight children are exposed to and the progression of near-sightedness. The more sunlight, the children the slower the progression was.
Teens also need sunlight. In a research, scientists studied over 3,000 people; 371 with near-sightedness and 2,797 without and found that the more UVB radiations they were exposed to during their teen years, the less likely they were to get near-sightedness.
In the longest-ever study on the progression of near-sightedness, it was found that children who wore their glasses while reading had a slower near-sightedness progression that those who didn’t wear them.
After three years, both groups wore the glasses continuously. Twenty years later, there was no difference between the groups.
Conclusion: Wearing your glasses is not making your eyesight any worse, but not wearing them could.
