I have had 20/20 vision my entire life and never even slightly struggled with seeing anything. When I arrived to Penn State as a freshman and began to go to class again after a long summer, I noticed that I was having trouble seeing the board in my large lecture classes. I then began to pick up on little things like not being able to clearly recognize the face of a person who is across the room from me in these classes. It seemed to have gone from perfect eyesight to a condition in which I absolutely needed glasses with no transition period. I began to question why this was happening. I was not sure if I had deficiencies with my vision before but have never noticed or it was a new thing happening to my sight. I knew that if it was the latter conclusion, I wanted to know what causes this!
As many people say – do not look up symptoms online because it will cause you to self-diagnose yourself with a rare and deadly disease when you are most likely fine! When I began to research the causes of lost eyesight, the results gave me a little bit of anxiety! There are many different conditions that link are mentioned here that link up with vision change, for example: presbyopia, glaucoma, and diabetic retinopathy, Naturally, these big words began to scare me so I called up my parents to inform them that I was soon going to die, and they reminded me that I am fine, and I have also been genetically doomed with a worsening vision.
It is likely that if one or both of your parents have poor eyesight, you will also experience this at some point in your life. Personally, I began to have trouble seeing things that are far away and have no trouble seeing things that are close by, which is called nearsightedness. Although genetics is a large factor into the reasoning behind changing vision, it can also be do to your surroundings and daily activities or habits. One example I found when researching is that a lot of reading can cause ones eyesight to worsen. The worsening of my eyesight triggered a thought that it would be interesting to conduct a trial on whether genetics or environment has a more prominent affect on the human eye.
