Answer 2

Although a direct cause is not known precisely, it is basically a problem of old age. The eye loses its ability to focus on near objects, just as the body loses its ability to produce hair pigment or to retain its elasticity in the skin is diminished or lost.

Answer 3

Well there are many kinds of myopia and why they occur you can look most of them up online but here is one main cause:

Elevation of blood-glucose levels can cause swelling in the eye lens

Answer 4

In the myopic eye, the focusing power of the cornea (the major refracting structure of the eye) and the lens is too great with respect to the length of the eyeball. Light rays are bent too much

Answer 5

the focusing power of the cornea (the major refracting structure of the eye) and the lens is too great with respect to the length of the eyeball. Light rays are bent too much, and they converge in front of the retina

Answer 6

said to be caused by an elongation of the eyeball. This means that the oblong (as opposed to normal spherical) shape of the myopic eye causes the cornea and lens to focus at a point in front of the retina

Answer 7

Use of Sulphonamides.
