Many things can affect the health of your eyes – from poor overall health, to diabetes, to simple old age – but nothing will affect your vision quite like direct exposure to the sun.
Failing to protect your eyes properly during long periods in bright sunlight has even been shown by some studies to contribute towards macular degeneration or cataracts, due to damage caused by ultraviolet (UV) rays. Sunbathing and using sunbeds can be especially detrimental, but being outside playing sports or walking for long periods – or even activities that combine both, such as golf – can be just as risky.
