Eye health: simple habits that protect your vision
Your eyes work every day. Small, practical habits keep them healthy and reduce the chance of surprise problems. Below are clear steps you can start using now — no fancy gear, just good routines and smart choices.
Everyday habits that actually help
Follow the 20-20-20 rule when you use screens: every 20 minutes look at something 20 feet away for 20 seconds. It cuts eye strain and forces you to blink more, which prevents dryness. Position your screen about an arm’s length away and slightly below eye level so your eyes relax naturally.
Wear sunglasses that block 100% UVA and UVB (look for UV400). UV rays speed up cataract formation and harm the retina over time. When you do yard work or use power tools, wear safety glasses — they prevent injuries that can cause permanent vision loss.
Keep contact lenses clean and replace them as directed. Sleeping in lenses not made for overnight use raises the risk of infection. If your eyes get red, painful, or your vision blurs, remove lenses and see an eye care professional right away.
Eat simple, eye-friendly foods: leafy greens (kale, spinach), eggs, and oily fish like salmon. These provide lutein, zeaxanthin, and omega-3s — nutrients linked to healthier retinas and less dry eye. If you take supplements, tell your doctor so they fit your overall plan.
Medications, symptoms to watch, and when to act
Some medicines can affect your eyes. For example, steroid use can raise eye pressure or contribute to cataracts over time. Antihistamines and some antidepressants may cause dry eyes. Certain antibiotics and other drugs list visual changes as a possible side effect. Read the leaflet, ask your pharmacist, and report any new vision changes.
Know the urgent signs: sudden visual loss, flashes of light, a new shower of floaters, severe pain, or a curtain-like shadow across your vision. These can mean retinal detachment, infection, or acute glaucoma. Get help immediately — faster care often means better outcomes.
Schedule regular eye exams. A comprehensive check finds issues early — glaucoma, macular changes, and diabetic retinopathy can be managed far better when caught early. Ask your eye doctor how often you should come back based on age, health, and risk factors.
