As we age, our eyesight declines, increasing the risk of eye diseases like macular degeneration and cataracts. However, many healthy habits can help maintain eye health, preserve vision, and prevent disease.

Wear sunglasses outdoors. Sunglasses are not just a fashion accessory; they protect your eyes from the sun's ultraviolet (UV) rays. When choosing sunglasses, prioritize safety over style. Look for lenses that block 99-100% of UVA and UVB radiation. Contact lens wearers can choose lenses with built-in UV protection. However, wearing sunglasses over contact lenses offers the best protection.

Rest your eyes regularly. If you spend all day working on a computer or looking at your phone, blink frequently. Every 20 minutes, look at an object 6 meters away for 20 seconds. This reduces eye strain and gives your eyes a break. Spending time outdoors and limiting activities that require continuous close-up vision are also good habits for your eyes, helping to prevent vision loss.

Don't ignore eye abnormalities. If your eyes are itchy or red, soothe them with a cold compress, antihistamines, or eye drops as prescribed by a doctor. Rinse your eyes with saline solution if they feel gritty. If discomfort persists or if you experience eye pain, discharge, swelling, or light sensitivity, consult an ophthalmologist.

Clean contact lenses regularly. Always wash and dry your hands before handling contact lenses. Clean, rinse, and dry your lens case with saline solution every time you remove your lenses. Don't wear contact lenses while sleeping or swimming, and replace your lens case every two to three months. Only use cleaning solutions and eye drops recommended by your eye doctor.

Manage your weight. Being overweight or obese increases the risk of diseases like diabetes and other systemic disorders that can eventually lead to vision loss. A healthy diet and regular exercise help maintain a healthy weight and reduce the risk of eye damage caused by diabetes, high blood pressure, and obesity.

Get regular eye exams. Generally, people aged 18 to 60 should have an eye exam at least every two years, or more frequently if there are any abnormalities. People over 60, regular contact lens wearers, or those with risk factors like diabetes, high blood pressure, or a family history of eye disease should have an annual exam.
