Assuming good health, vision should be at its peak. Some people who work with VDUs can find their mid to short distance vision suffering slightly in their 20s and 30s, prompting the need for glasses or a change in their prescription.

Protect your eyes from UV light, cigarette smoke and keep up to date with your eye examinations to keep them in the best shape.

In your 40s, presbyopia can become noticeable. This is when the lens in your eye begins to harden, making it harder to focus on close objects. Reading glasses or multifocal glasses will be necessary for most people by this age.

In your 50s, the risk of glaucoma increases – especially for those with diabetes. Glaucoma is caused by a build-up of pressure in the eye, leading to loss of peripheral vision, or tunnel vision. It’s especially important to feed and nourish yourself properly to combat late onset diabetes and to look after your eyes.

The development of cataracts is something everyone who lives long enough will face. The clouding of the lens is caused by tiny proteins clumping together, eventually causing dull, misted vision. It’s a common eye condition of people over 60.

Evidence shows that UV exposure can accelerate cataract formation, so proper UV protection is important throughout life. Surgery is simple and effective, but prevention is better. Preliminary research shows that diet and nutrition play a role in their formation.
