Many of us start the new year by examining how we can live healthier lives. However, we may overlook a key part of our health in this evaluation: our eyesight. Whether or not you have 20/20 vision, it’s a good idea to launch 2020 by ensuring your eye health is in top shape.

Here are five tips on how you can keep your eyes healthy this year.

One, if you wear glasses or have eye-related symptoms, schedule an exam by an ophthalmologist to screen for eye diseases like glaucoma and to ensure your vision is at its best. And make sure if you wear contacts or eyeglasses that your prescription is up-to-date.

On that note, if you do wear contact lenses, make sure you’re taking proper care of them. This includes using the right cleaning solution and a clean storage case if the lenses are reusable or disposing of daily lenses. Also, refrain from showering or sleeping in your contact lenses, as that could cause infections and long-term problems for your eyes.

Next, use sunglasses year-round to protect your eyes from the sun’s ultraviolet, or UV, rays. Yes, this includes the winter months. Excessive exposure to UV rays is associated with harmful eye diseases.

You can also strengthen your eyes from the inside by eating eye-healthy foods that are rich in nutrients like beta carotene, including spinach, sweet potatoes and carrots.

Finally, follow the 20/20/20 rule. We spend a lot of our time staring at computer, smartphone or tablet screens, and that can strain our eyesight. To relieve the stress on your eyes, every 20 minutes, look at an object 20 feet away for at least 20 seconds.

With these tips in hand, you can look ahead to an eye-healthy year.
