Eyeglasses and Their Role in Eye Health

eyeglasses and their role in healthThere’s a common belief that once a person starts using glasses for near or farsightedness, their eyes will get lazy by adjusting to the glasses and that over time this will lead to more-rapidly worsening vision. In many cases, this is actually the opposite from the truth, as glasses can reduce eye strain and help slow down some times of vision loss, promoting healthy eyes.

There are isolated cases where eyeglasses can have a small negative impact on long-term vision strength. However, it’s impossible to identify which patients will experience this change. For the most part, people who have eyes that are going to get worse will experience this deterioration with or without eyeglasses, so it’s not the wearing of glasses that does the harm, but just the nature of the eyes. In this situation, struggling through nearsightedness or farsightedness won’t be any better than using glasses, and will probably just cause headaches and frustration over not being able to see properly. Plus, anything that puts too much strain on the eyes will tend to have a detrimental effect.

For those whose eyes would normally be fine if they worked on a farm instead of in a job what requires close up work using a computer – which is very common – glasses can even be helpful. For one thing, with the right corrective eyewear the activities that tend to cause eye strain and thus lead to Myopia or Hyperopia strain the eyes less. Generally, someone who is nearsighted will be given glasses to improve his or her long distance vision. However, some doctors prescribe weak reading glasses for people with minor cases of myopia to help prevent near-work induced myopia. In essence, this makes the eyes work like the object being read is farther away than its physical distance, helping reduce the nearwork-related strain.

Of course, beyond corrective glasses, and the obvious choice for corrective surgery, there are a few other things people can easily do to maintain healthy vision. The best is to pay attention to the basics: diet, not smoking, lead a healthy lifestyle, and paying regular visits to the eye doctor. Several healthy behaviors, including paying attention to how long you look at a computer screen and taking the time to rest your eyes and refocus them every 20 minutes, and doing eye exercises to keep their focusing ability strong, are very helpful no matter what your vision. Even if you need eyeglasses, paying attention to these basic factors can help control weakening eyes, as can the right glasses when applied to appropriate personal circumstances.
