Most people don’t notice their vision changing until problems show up. The good news: small daily habits cut your risk of irritation, infections, and long-term damage. Below are clear, practical steps you can start right now.
Start with screen time. Use the 20-20-20 rule: every 20 minutes look at something 20 feet away for 20 seconds. That reduces strain and keeps your blink rate normal. Blink more often when using screens and consider blue-light filters if you work long hours at a computer.
Wear sunglasses that block 100% of UVA and UVB rays when you're outdoors. UV exposure adds up over years and raises the risk of cataracts and other eye changes. For sports and yard work, pick wraparound lenses to stop debris or wind from irritating the eyes.
Nutrition matters. Eat foods with lutein, zeaxanthin, omega-3s, and vitamin C — think leafy greens, eggs, oily fish, and citrus. These nutrients support retina and macular health. If your diet is limited, a daily eye-support supplement can help, but check with your doctor first.
Sleep and hydration affect eye comfort. Not enough sleep increases redness and dry eye. Drink water throughout the day — dehydration makes eyes feel gritty and tired. If you fly a lot or work in dry environments, use a humidifier or preservative-free artificial tears.
If you wear contacts, follow replacement and cleaning rules exactly. Don’t sleep in lenses unless they’re approved for overnight wear. Replace the case every three months and use fresh solution; tap water and homemade mixes invite infections.
Schedule a comprehensive eye exam at least every 1–2 years, or more often if you have diabetes, high blood pressure, or a family history of eye disease. Exams catch problems early — often before you notice symptoms.
Seek urgent care for sudden vision loss, flashes of light, a sudden increase in floaters, severe eye pain, or bright halos around lights. These can signal retinal detachment, acute glaucoma, or other conditions that need immediate treatment.
Minor issues like a stye or mild irritation often respond to warm compresses for 10 minutes, 2–3 times a day, and keeping the area clean. Use over-the-counter artificial tears for dryness, but stop if symptoms worsen. Also be aware that common medicines (some antihistamines, decongestants, and certain blood pressure drugs) can dry your eyes — mention this to your doctor.
Protecting your eyes doesn’t require dramatic changes. Small, consistent habits — regular breaks, proper sun protection, good nutrition, safe contact use, and routine exams — go a long way toward keeping your vision sharp for years to come.
