How Eyeglasses Can Help To Correct Vision
If you've recently found yourself straining to read something close up or far away, then it is likely that you are in need of some kind of visual aid in order to see better. These visual aids, anything from glasses to contact lenses to even LASIK surgery, can greatly improve your vision and make using your vision a less stressful experience. As your local Helena vision provider, we are cognizant of how important vision care is as well as how important it is to educate our patients on why they should look out for their vision. In this article, we'll discuss how eyeglasses work to correct vision.
How Do Eyes Work In The First Place?
In order to find out how glasses work, we need to figure out how the eye works first. The eye is made up of many different parts and is each responsible for working properly to generate good vision. The cornea helps the eye focus while the pupil lets light enter the eye. The lens of the eye helps it focus while the retina at the very back of the eye receives the light that the lens has focused and converts it into neural signals. These signals are then sent to the brain for visual recognition. When one or more of these parts of the eye does not work, a faulty visual stimulus is sent to the optics nerves, resulting in poor vision.
How Do Glasses Correct Faulty Vision?
We mentioned how vision starts by light entering the pupil and is, in turn, focused by the cornea and lens before moving onto the retina for neural recognition. Glasses are called corrective lenses because they bend the light ray entering the pupil in such a way that it makes it easier for the cornea and lens to focus the light. The light entering is focused by the lens on the right spot in the retina. This is different for everyone and is the reason why other people's glasses are blurry when you put them on.
Why Can I See Far Away but Not Close Up?
When you can read things that are far away, that means you are far-sighted. If it was the opposite way around, then you would be near-sighted. When you are far-sighted, you'll have trouble reading things up close. If you find yourself getting tired easily after only reading for a few moments, it might be a sign that you are indeed far-sighted. On the other hand, nearsightedness or myopia results from trouble in seeing things that are farther away. In both cases, a pair of glasses can help correct the problems associated with both issues.
