There is a genetic link to the condition, so it makes sense to have your eye health checked regularly if you have a blood relative who has developed AMD.

Researchers agree that smoking definitely increases your chances of developing AMD. Research is continuing into other factors, including:

• high blood pressure and cardiovascular disease – there may be a link between these conditions of the circulatory system and AMD;
• exposure to the sun – ultraviolet rays may cause damage to the pigmented layer of cells in the eye.

Researchers are also looking at the possibility that vitamins C and E, zinc and other nutrients such as lutein and zeaxanthin (which are found in green leafy vegetables), may help to prevent AMD.
