What are the most common vision problems? Some people take their health for granted and don't notice the effects it could have on them in the future, but others don't even stop to think about their vision. Vision is one of the most important parts of your body. Without being able to see you would not see the most wonderful things in the world. Teens care so much about their TV shows and their cell phones, but without your eyesight you wouldn't be able to watch television or text or use all those social networks. There are many ways to test your vision. Eye problems increase with age, reminding us to go and make an appointment with the eye doctor. Being able to see is a long process that runs through the anatomy of an eye. The eye can only capture information already processed by the brain, but it can also receive it through reflected light. Once the reflected light enters the eye, the internal surface, called the retina, is already in focus. Light receptors transform light into electrical signals and transmit the signals to the brain along the optic nerve. Once the brain has received the information from the optic nerve, it will transform into an image. The cornea is a part of the eye that looks like a bulge at the front of the eye. The cornea collects all the light and then goes to the pupil. The pupil is a hole in the center of the iris, depending on how much light there is the pupil can become larger or smaller. The less light, the larger the pupil will become and the more light there is, the pupil will become smaller. Once the light has already passed the pupil, it passes through the lens, which is located behind the iris. After the lens, light passes through the lens. vitreous humor and finally the light comes to concentrate on the retina....... middle of paper...... milies conditions. In most conditions you can tell when you get them because your eyes are uncomfortable or you see blurry, but with these conditions it's hard to tell if you have it because it doesn't even hurt. So what you need to watch out for are flashes of light and dimming of your device. There are many ways this condition can be tested for. They usually give you an eye dilator once the results are received to see if the retina is detached. It is best to get checked first to avoid vision loss due to retinal detachment. There are many ways to treat a laser retinal detachment or frostbite, what this treatment does is that it can only repair a retinal tear if it is checked early enough. Pneumatic retinopexy is another treatment that involves injecting a gas bubble into the eye that presses on the retina.
