As we all know that vision and eyes are important to us. so we need to save our vision and care for our eyes. 1. eye exam. Regular eye exams are important because there are several eye conditions that can develop in the eye that have no symptoms.These eye conditions include optic nerve atrophy, which can be caused by poor blood flow, eye diseases such as glaucoma or a stroke. Symptoms include reduced field of vision and faded or dimmed vision, according to the National Institutes of Health.2. Wear sunglasses.Some people think sunglasses are for looks, but they're not.I would recommend that they always wear sunglasses because the sun is very damaging where we live.too much sunlight can cause eye cancers, such as intraocular melanoma-the most common eye cancer in adults. Excessive exposure to sun's rays may also cause macular degeneration, one of the major causes of vision loss in the U.S., or cataracts, the most common cause of treatable blindness worldwide.3. Be mindful of what you eat.What you eat can also affect your vision, said Alomia, who suggests sticking to a diet high in antioxidants and omega-3 fatty acids. According to the CDC, eating fruits and veggies like spinach, kale and collard greens can help keep eyes healthy. Sources of omega-3 fatty acids include salmon, tuna and halibut.4. Watch your weight.Being overweight can put you at a higher risk for certain diseases that can affect your sight, like diabetic eye disease or glaucoma, according to CDC.Being overweight can also put you at risk of developing pseudotumor cerebri, which can cause you to lose vision temporarily, or blurred vision, according to NIH.5. Practice good contact lens hygiene. Leaving your contacts in overnight can cause a lack of oxygen, which can ruin the cornea, the eye's outermost layer.People who wear contact lenses should also make sure to wash their hands before taking out or putting in their contact lenses and use only the contact lens solution recommended by their doctor, according to CDC. 6. Give your eyes a break. If your job requires you to spend a lot of time looking at a computer or focusing on one thing, CDC recommends following the 20-20-20 rule. Every 20 minutes, look away about 20 feet in front of you for 20 seconds to help reduce eyestrain.
