Regular eye tests are important to detect and diagnose eye problems early. Eye tests can be arranged through an optometrist, by referral to an ophthalmologist or you can speak to your GP. Referrals to an ophthalmologist can be made by a GP or an optometrist.
Glasses are typically used for vision correction, such as with reading glasses and glasses used for nearsightedness. Safety glasses provide eye protection against flying debris for construction workers or lab technicians; these glasses may have protection for the sides of the eyes.
Sunglasses or sun glasses are a form of protective eyewear designed primarily to prevent bright sunlight and high-energy visible light from damaging or discomforting the eyes. They can sometimes also function as a visual aid, as variously termed spectacles or glasses exist, featuring lenses.
