Many serious eye diseases do not have any dramatic symptoms. Some people with serious eye diseases do not even realise that there is anything wrong until their eyes have suffered irreversible damage. Annual checkups are best done from age 20, although waiting until you have symptoms is hardly ideal. For example, glaucoma in its early stages is a silent thief of sight. It could take 10 years to cause a noticeable problem, by which time the changes are irreversible. Depending on your risk factors for eye diseases and your current symptoms or illnesses, your eye doctor may recommend that you have exams more often.
Cataracts are a cloudiness that form in the lens of the eye. The lens is normally clear. Poor vision occurs because the cloudiness interferes with light entering the eye. Symptoms are associated with blurring or fuzziness of vision. Thus making it difficult reading small print or seeing street signs. There may be an increased sensitivity to light and glare, especially in bright sunlight or when driving at night.

Retina damage from diabetes is caused through excessive amounts of glucose in the blood. This high blood glucose, also called blood sugar, can damage many parts of the body, such as the heart, blood vessels, eyes, and kidneys. The early stages of diabetic retinopathy usually have no symptoms. The disease often progresses unnoticed until it affects vision. Bleeding from abnormal retinal blood vessels can cause the appearance of “floating” spots. These spots sometimes clear on their own. But without prompt treatment, bleeding often recurs, increasing the risk of permanent vision loss.

Glaucoma is the name given to a group of eye diseases which the optic nerve at the back of the eye is slowly destroyed. In most people this damage is due to an increased pressure inside the eye - a result of blockage of the circulation of aqueous, or it's drainage. One of the most common forms of glaucoma has no symptoms until the eye is lost at a later stage. Damage progresses very slowly and destroys vision gradually, starting with the side vision. One eye covers for the other, and the person remains unaware of any problem until the majority of the nerve fibers have been destroyed, and a large part of vision has been destroyed.

Macular Degeneration (MD) is the leading cause of blindness in Australia, affecting central vision. MD is primarily age related and most frequently affects people over the age of 50. MD can be detected in its very early stage before any visual symptoms occur, by medical examination of the retina. As MD progresses, the center of a person's visual field may become smudged, distorted or lost. This defect causes problems with reading, driving, watching TV and recognizing faces. Early detection of any form of MD is crucial, because any vision lost cannot be regained.
