Find out why regular eye tests (sight tests) are important and how a healthy lifestyle can help maintain good vision.
It's easy to neglect your eyes because they often do not hurt when there's a problem.
Having an eye test will not just tell you if you need new glasses or a change of prescription – it's also an important eye health check.
An optician can spot many general health problems and early signs of eye conditions before you're aware of any symptoms, many of which can be treated if found early enough.
The NHS recommends that you should get your eyes tested every 2 years (more often if advised by your ophthalmic practitioner or optometrist).

Getting out in the sun is important for your general health, but you need to protect yourself.
Never look at the sun directly, even when something exciting such as an eclipse is happening. Doing so can cause irreversible damage to your eyesight and even lead to blindness. Several studies also suggest sunlight exposure is a risk factor for cataracts.
Wearing a wide-brimmed hat or sunglasses can help protect your eyes from UV rays. The College of Optometrists recommends buying good-quality dark sunglasses – these needn't be expensive.
Look for glasses carrying the CE mark or the British Standard BS EN ISO 12312-1:2013, which ensures they offer a safe level of ultraviolet protection.
