The tests are painless and usually take about 30 minutes. Your pupils may be dilated with drops, which can make your vision blurry for a few hours, so bring sunglasses.
Treatment
Treatment depends on the specific eye problem. This article focuses on lifestyle measures that support eye health and prevent problems.
Self-care at home

- Adjust screen brightness and position to reduce glare.
- Blink often and use lubricating eye drops as recommended by your pharmacist or doctor.
- Wear sunglasses with UV protection on sunny days.
- Take regular breaks from close work.
Medical treatments
Your doctor may prescribe medications, eye drops, or refer you to a specialist depending on any condition found. Always discuss your options with your healthcare provider.
Living with this condition
Make small changes like adjusting screen brightness and blinking regularly. Keep a pair of sunglasses handy and set reminders to take screen breaks.
Lifestyle tips
- Get enough sleep to rest your eyes.
- Stay hydrated to help prevent dry eyes.
- Avoid smoking and limit alcohol.
- Use protective eyewear for sports or DIY work.
Diet and exercise
Eat green leafy vegetables, fish, nuts, and citrus fruits. Regular physical activity helps your overall health and can reduce the risk of conditions that affect eyes, like diabetes.
Mental health and emotional wellbeing
Chronic eye problems or vision loss can cause emotional strain. If you feel anxious or low, talk to your doctor or a trusted healthcare professional for support.
Prevention
Many eye problems can be prevented or delayed with healthy habits like protecting your eyes from the sun, not smoking, and having regular eye tests.

- Ignoring warning signs can lead to permanent vision loss.
