Good vision is easy to take for granted until something changes. As an ophthalmologist, here are five simple habits I recommend to almost every patient, regardless of age.
1. Follow the 20-20-20 rule
If you spend hours on screens, every 20 minutes look at something 20 feet away for 20 seconds. This small break reduces digital eye strain, dryness, and the headaches that come with prolonged near-focus work.
2. Don’t skip the sunglasses
UV exposure adds up over a lifetime and contributes to cataracts and other damage. Choose sunglasses that block both UVA and UVB rays, not just dark-tinted lenses, which can actually cause pupils to dilate and let in more UV light.
3. Eat for your eyes
Leafy greens, fish rich in omega-3s, and colorful fruits and vegetables supply lutein, zeaxanthin, and antioxidants that support the retina and may slow age-related changes.
4. Get regular eye exams, even without symptoms
Many eye conditions, including glaucoma, develop silently before vision loss is noticeable. A routine dilated exam can catch problems years before you’d feel anything wrong.
5. Respect your contact lenses
Never sleep in daily lenses, avoid wearing them in water, and replace them on schedule. Improper contact lens hygiene is one of the most common causes of preventable corneal infections I see in clinic.
None of these habits require special equipment or a lot of time, but together they go a long way toward protecting your sight for the long run.
