Eye health: simple habits that protect your vision

Your eyes work nonstop. Small daily choices make a big difference — from how you use screens to what you eat. This page gives clear, usable tips to prevent common problems, spot warning signs, and get the right care when you need it.

What can go wrong? Dry eyes, blurry vision, eye strain, cataracts, glaucoma, and age-related macular degeneration are the usual suspects. Risk factors are concrete: getting older, having diabetes or high blood pressure, smoking, too much unprotected sun, and long hours on screens. Knowing which risks apply to you makes prevention practical, not scary.

Start with easy daily habits. Keep screens at arm’s length and a bit below eye level. Use the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds. Blink more when reading or using devices — that helps tear coverage and prevents dryness. Pick soft, warm lighting rather than harsh overhead glare, and adjust text size so you don’t squint.

Diet matters. Foods rich in lutein and zeaxanthin (spinach, kale, eggs), omega-3 fats (salmon, mackerel, walnuts), and vitamins A, C, and E (carrots, citrus, nuts) support eye tissues. You don’t need supplements unless a doctor recommends them, but regular servings of these foods help maintain healthy vision over the years.

When to see a doctor right away

Some signs mean you should get urgent care: sudden vision loss, flashes of light, a sudden increase in floaters, severe eye pain, double vision, or a red eye with nausea or vomiting. These can signal retinal detachment, acute glaucoma, infection, or other conditions that need immediate attention.

For routine care, most adults should have an eye exam every 1–2 years. If you’re over 60, have diabetes, a family history of glaucoma, or wear contact lenses, checkups should be more frequent. Kids need eye checks too — catching vision problems early makes school and learning easier.

Practical tips for contacts, drops and long-term care

If you wear contacts, follow the replacement schedule and cleaning rules your eye doctor gives you. Never sleep in lenses unless they’re specifically approved for overnight use. For dry eyes, use preservative-free artificial tears; avoid long-term use of redness-reducing drops because they can worsen symptoms over time.

Manage chronic conditions that affect sight. Keep blood sugar and blood pressure under control, quit smoking, and get regular screenings if you’re at risk for glaucoma or macular degeneration. If surgery comes up — for example, cataract removal — ask about outcomes, recovery time, and what to expect afterward.

Quick checklist: take screen breaks, wear UV-blocking sunglasses, use protective eyewear for work or sports, eat eye-friendly foods, and book regular exams.
