Without eyesight we are deprived of the ability to perform many activities. Reading and driving is impossible while functioning in general becomes much more difficult. To maintain the health of your eyes you need to understand a bit about how they function. Eye care lab dot com provides information on eyes, eye diseases, and treatments for eye disease.
Eyes are an amazing structure
The eye can be compared to a working camera complete with shutter, lenses and focusing mechanisms. The pupil controls the amount of light that is let into the retina. The pupil has the ability to open and close like a shutter. The light that is let in sends and upside down image to the retina, which is reinterpreted by the brain as right side up. In essence the retina can be compared to film upon which an image is registered.
Anatomically the structure of the eye is very complex. Some of the components of the eye hold fluids such as tears and blood, which help nourish and lubricate the eye tissues. The muscles of the eye help the iris and pupil to move and focus. The eyelids and the epithelium of the cornea help protect the eye from injury. There are also sensors in the eye that send information to the brain to indicate sensations like pain.
Eye problems
The best cure for blindness is prevention. Part of a healthy eye care regime is to make regular visits to the eye doctor to have your eyes checked for common problems. Regular eye exams can help determine if your vision needs correcting or reveal the cause of any vision problems. With early detection many eye diseases, including age related vision problems can be treated and prevented.
It is quite common for people to suffer from refractive errors of the eyes. These are simply known as farsightedness or nearsightedness. Farsighted people can’t see up close and nearsighted individuals can’t see far away.
The arson that a shortsighted person can’t see objects far away is because the lens in the eye focuses only on the sharpest image in front of the retina instead of it. This vision problem is easily corrected by placing a concave lens in front the eye. Conversely if a person is long sighted they can’t see objects up close. This is because the lens of the eyes can only focus on the sharpest image behind the retina instead on it. This is corrected by placing a convex lens in front of the eye.
Farsightedness or nearsightedness is common but there are also much more complex refractive disorders such as astigmatism. The eyes can also be afflicted by disorders such as conjunctivitis (pink eye), blepharitis, allergies diabetic retinopathy and other conditions. Cataracts and glaucoma are prevalent all over the world.
