How can I protect my vision, and when do I need an eye examination?

Quick answer

Managing chronic conditions, avoiding smoking, protecting against sun and injury, and safe contact-lens care support vision. Eye-examination timing depends on age, symptoms, diabetes and family history; a single annual rule does not fit everyone.

Everyday protection

Use UV-blocking sunglasses and safety eyewear for hazardous tasks. Wash hands before handling contacts and follow cleaning and replacement instructions. Balanced nutrition helps; eye supplements are not required for everyone.

Screens and preventive examinations

Take distance-viewing breaks, blink regularly and adjust lighting for comfort. A glasses prescription check does not replace an eye-health examination when indicated. Conditions such as glaucoma or diabetic retinal disease may initially have no obvious symptoms.

Sudden visual change must not wait

Sudden vision loss, a curtain across vision, or new flashes and many floaters needs urgent assessment. So does severe pain with redness or altered vision. Do not wait for a routine appointment or rely on lubricating drops.
