Some eye diseases and conditions are caused by genetics and can't be avoided no matter what you do to take care of your eyes. However, not all eye problems or diseases are caused by genetics, and there are many things that you can do to protect your eyes and your vision, even as you age. While only your optometrist can give you personalized advice for taking care of your eyes in particular, note some tips that everyone can consider for protecting their vision.

Be tested for diabetes

Diabetes affects the blood vessels that are in the retinas, and this condition is a leading cause of blindness for many adults. It's imperative that you be tested for diabetes as often as recommended if you have a history of this illness in the family or if your doctor says you're at risk of the condition for any reason. It's also good to be mindful of what you eat and your everyday activity levels, so you can avoid obesity and the increased risk of diabetes that often goes along with added body weight. If you need assistance in managing your weight, ask your doctor for help.

Wear sunglasses

Harsh sunlight can make you squint, wearing out the muscles in the eyes. Overexposure to UV rays can also increase your risk of cataracts. Always wear sunglasses when it's bright outside, and this includes during the wintertime, when sunlight can reflect off snow and cause a harsh, painful glare.

Take a break from the screen

Focusing on a computer screen all day, or on your small phone or tablet, can also wear out the muscles of the eyes. This can also cause dry eyes, and the eyes need moisture to be healthy. It's good to look away from the computer screen for several minutes while working; focus on something across the room or just close your eyes to give them a break, and this can protect them from overuse and eventual damage.

Update your prescription

If you wear glasses or contact lenses, it's important that you get your prescription updated regularly. An old, outdated prescription can make your eyes work too hard to focus, leading to dry eyes, muscle strain, headaches, and blurred vision. However, you might not even realize this is happening with your vision, as this change may occur gradually. Your optometrist can tell you how often you need to get your eyes examined for a new prescription, so be sure to do this as recommended to protect your eyes and your vision.
