When I was little I never really had problems with my eyes, I could always see everything near and far and never had an issue. As I got older my eyes progressively got worse, to the point where I wasn’t even noticing it. I never thought I needed glasses or that I had a vision problem, I just figured that I was far from the board or the markers were old and they were writing really light. I just figured from where I was everybody couldn’t see those things. It wasn’t til I took a vision test my 8th grade year that I realized that my vision was really bad for things that were at a distance. I ended up getting glasses today and pretty much wear them just in class, but I never thought that I would need glasses. None of my siblings, parents and even my extended family really ever had glasses. This led me to the question of whether or not problems with your vision are hereditary or not?
Most doctors claim that some vision problems are hereditary whereas others say they are more environment. A study conducted in London shows that eyesight problems are mostly hereditary. They conducted a study of 500 pairs of twins, the results showed that 85% of cases of nearsightedness and farsightedness in kids is due to the inherited traits from their parents.
I also ran across an article that had differing opinions on the topic. This article makes the claim that vision problems are due to environment. He makes claims about the substantial amount of people that need to wear glasses or contacts today as opposed to those before World War I.
I think that needing to wear glasses is more of an inherited trait that can be strengthened by environment. I think that yes over time if you stare at your phone all day or at a screen all day that it will eventually do damage to your eyes. But I think previously when we didn’t have phones and computers that people inherited the traits of being nearsighted or farsighted. It is a pretty interesting topic to read about. I would love to hear about other people’s opinions on the topic.
