Eye defects

Astigmatism
This defect is when the light rays do not all come to a single focal point on the retina, instead some focus on the retina and some focus in front of or behind it. This is usually caused by a non-uniform curvature of the cornea. A typical symptom of astigmatism is if you are looking at a pattern of lines placed at various angles and the lines running in one direction appear sharp whilst those in other directions appear blurred. Astigmatism can usually be corrected by using a special spherical cylindrical lens; this is placed in the out-of-focus axis.

Colour-blindness
A genetic defect found usually in males. A colour blind mother will always produce colour blind sons. Colour blind people are unable to differentiate between red and green. It can easily be detected through a special chart with various colour dots.

Farsightedness
Also known as Hyperopia, this is a defect of vision in which there is difficulty with near vision but far objects can be seen easily. The image is focused behind the retina rather than upon it. This occurs when the eyeball is too short or the refractive power of the lens is too weak. Hyperopia can be corrected by wearing glasses/contacts that contain convex lenses.

Presbyopia
A defect in which accommodative power is gradually lost with increasing age as the lens‘ converging power decreases.

Nearsightedness
Also known as Myopia, this is a defect of vision in which far objects appear blurred but near objects are seen clearly. The image is focused in front of the retina rather than on it usually because the eyeball is too long or the refractive power of the eye’s lens too strong. Myopia can be corrected by wearing glasses/contacts with concave lenses these help to focus the image on the retina.
