Do you know how your eyes works or function? It begins when light rays are reflected off an object and enter the eyes through the cornea, the transparent outer covering of the eye.
The cornea bends or refracts the rays that pass through a round hole called the pupil. The iris, or colored portion of the eye that surrounds the pupil, opens and closes (making the pupil bigger or smaller) to regulate the amount of light passing through. The light rays then pass through the lens, which actually changes shape so it can further bend the rays and focus them on the retina at the back of the eye. The retina is a thin layer of tissue at the back of the eye that contains millions of tiny light-sensing nerve cells called rods and cones, which are named for their distinct shapes. Cones are concentrated in the center of the retina, in an area called the macula. In bright light conditions, cones provide clear, sharp central vision and detect colors and fine details. Rods are located outside the macula and extend all the way to the outer edge of the retina. They provide peripheral or side vision. Rods also allow the eyes to detect motion and help us see in dim light and at night. These cells in the retina convert the light into electrical impulses. The optic nerve sends these impulses to the brain where an image is produced.

Complex right? That's why you must taking care your eyes carefully or else you will have some bad eyes problem.
Eyesight problem can be categories on 2 symptoms, Long sighted problem ( known as hyperopia - affect a person ability to see close object ) and Short sighted problem ( known as Myopia - affect a person ability to see far object ).
Here is some tips on how to improve eyesight
Most people who want to improve eyesight tend to solve them by wearing Glasses. But beware, wearing Glasses is just to improve your vision only but it will not help to solve your eyes problem. It is the only for short term solution.
Actually there is a long term solution to solve your eyesight problem that is by LASIK surgery. It can give you a long term solution for eyesight problem but also there are some negative stigma on the LASIK surgery.
There are some risk involved for example some problems may occur when the doctor cuts the flap, which can permanently affect vision.
Involved high cost.
LASIK can rarely cause a loss of "best" vision. Your best vision is the highest degree of vision that you achieved while wearing your contacts or eyeglasses
That's why the best solution for the eyesight problem is by natural ways. There are many methods that you can use to improve your eyesight, one of them is by using Dr. Bates program. Dr Bates felt glasses were harmful and never necessary. Dr. Bates self-published a book as well as a magazine (and earlier collaborated with Bernarr MacFadden on a correspondence course) detailing his approach to helping people relax such "strain", and thus, he claimed, improve their sight. His techniques centered on visualization and movement. He placed particular emphasis on imagining black letters and marks, and the movement of such. He also felt that exposing the eyes to sunlight would help alleviate the "strain" thus improving the eyesight.
