Living an overall healthy life is good for your eyes. You can start taking steps toward living a healthy life by:

Maintaining a healthy weight. Being overweight or obese increases your risk of developing diabetes and other systemic conditions, which can lead to vision loss, such as diabetic eye disease or glaucoma.

Eating healthy foods. You’ve heard carrots are good for your eyes, but eating a diet rich in fruits and vegetables, particularly dark leafy greens such as spinach, kale, or collard greens, is important for keeping your eyes healthy too. Research has also shown there are eye health benefits from eating fish high in omega-3 fatty acids, such as salmon, tuna, and halibut.

Not smoking. Smoking is as bad for your eyes as it is for the rest of your body. Research has linked smoking to an increased risk of developing age-related macular degeneration, cataracts, and optic nerve damage, all of which can lead to blindness.

Managing chronic conditions. Many conditions, such as diabetes, hypertension, and multiple sclerosis, can greatly impact vision, resulting in inflammation of the optic nerve, diabetic retinopathy, glaucoma, and even blindness. Managing these conditions with the help of your health care provider can often prevent these eye problems from occurring.
