Something that most people ask is what causes bad eyesight. In our modern society, more people are exposed to issues that can cause bad eyesight than in previous ages. Not surprisingly, longer life spans and more exposure to those issues causes more people to acquire this problem. Of course, as medicine has progressed further compared to previous ages, there are a number of things that a person can do in order to eliminate or at least alleviate the problem. This does not mean that a person should not worry about the causes of bad eyesight, but should be wary of them instead.
Glaucoma is one cause of failing eyesight. It is usually caused by increased pressure within the eye itself, which eventually causes the vision to become impaired. There are two forms of glaucoma, open-angled and closed-angle glaucoma. Open-angled happens slowly and with little pain, whereas closed-angled happens quickly and with acute pain. Also, closed-angle glaucoma has a number of other symptoms that make it a n ocular emergency. In both cases, the disease makes it harder to see over the course of the disease, eventually leading to blindness. Although there are a number of different theories on precisely how they work, there are a number of different ways of dealing with them, from transplants to experimental materials.
Eye strain is another issue. Reading used to be the main culprit, but that has been replaced by computer usage. In essence, by using one’s eyesight without allowing it to rest or not shifting ranges (such as looking away every so often at something further away), the eyes can lose the ability to focus on objects further away. This deterioration in eyesight in prevalent among scholars, scientists, and other professions where there is a lot of reading and writing. The solution is to usually simply rest the eyes every so often or to change one’s surroundings, forcing the eyes to focus on objects further away.
Merely aging will also cause some issues. The usual culprit is that the lens become thicker and less flexible over time, but any part of the eye can break down over time. Besides glasses, there is no real cure for this effect, as any surgery done to correct a problem merely slows it down. Suffice to say that research continues in this area, and there have been some interesting breakthroughs, but it remains mostly in the theoretical realm.
Although there is not a question as to what causes bad eyesight, there are thankfully ways to deal with it. Eye surgery is one possibility; although not advised for any but the most serious cases due to the possibility of infection making the problem worse, it can deal with a host of problems. In most cases, the person can be in and out within a day if not a few hours. Prescription glasses will always be available, and can be fun or sophisticated depending on the person’s preferred style. We know what causes bad eyesight, and there are solutions to the problem.
