Eye problems affect thousands of people all over the world. From mild visual impairment to complete loss of ability to see things, eye troubles may occur suddenly or worsen bit by bit, causing pain or staying painless.

Your eyes are complicated organs, which need numerous parts to work in harmony in order to give you clear vision.

When you look at something, light runs through the outer transparent layer, called cornea, then passes the opening in the middle of your eye (pupil) and is delivered into the lens. The lens focuses light onto the sensitive cells (retina), which transform images into signals and send them to the optic nerve. This bunch of fibers delivers signals to the part of the brain that can interpret information and enable you to see.

We all know that holding the smartphone very close to the eyes and staring at computer for a long time may damage our eyes and lead to poor vision.

Aging and genetics also play a role in developing various eye disorders.
