What types of eye complaints are there?

The common eye complaints are Blepharitis (inflammation of the eyelid margins), Cataracts (opacities in the lens of the eye), Macular Degeneration (sight threatening disease commonly associated with old age), Conjunctivitis (the most likely cause of red eye), Retinal Detachments (experience of flashing lights), Dry Eye (deficiency in production of the tear film) and Diabetic Retinopathy (can cause inconsistent vision / prescription).

What is Presbyopia?

The loss of the eye's ability to change focus to see near objects. The reasons for this loss of the power of accommodation are not yet fully known but it is conventionally said to be due to the lens becoming less elastic with time.

Presbyopia is associated with aging. It occurs in everyone. The first sign is often the need to hold reading material farther away.

What is Myopia?

Nearsightedness, the ability to see close objects more clearly than distant objects.
Myopia can be caused by a longer-than-normal eyeball or by any condition that prevents light rays from focusing on the retina.

Most forms of myopia can be managed with corrective lenses. Surgery is available to permanently correct some forms of myopia, although long-term effectiveness and safety has not been fully determined.

What is Astigmatism?

A common form of visual impairment in which part of an image is blurred, due to an irregularity in the curvature of the front surface of the eye, the cornea. The curve of the cornea is shaped more like a rugby ball rather than a normal spherical football.

The result is blurred vision at all distances. Only part of what you are looking at is in clear focus at any one time.

Astigmatism may be so slight that it causes no problems. Almost everyone has some degree of astigmatism. Significant astigmatism can cause headaches and eye strain and seriously blur vision
