Sleep: Sleep is very important in order to let our eyes get adequate amount of rest. Getting enough sleep also helps reduce dark under eye circles that many tend to struggle with. It is recommended for individuals to sleep a minimum of six hours, with the optimal sleeping period being a full 8 hours.
Eating Healthy: Consuming the right types of food, that deliver proper nutrients to your body, is essential for maintaining healthy eyesight. Healthy options for eyesight improvement include lots of vegetables, fruits, carrots and calcium. The best minerals for your eyes include vitamins A, B, C and E, as well as magnesium and zinc.
Don't read in moving vehicles: Reading in moving vehicles is stressful on the eyes and can even hurt them. If you do need to read, try to blink often to reduce strain and look away from book/screen more often and focus on distant objects.
Keeping a good reading posture: Awkward reading postures can lead to eye strain. Even at desk, make sure your computer monitor is situated such that you are slightly looking down to view the screen. Many people enjoy lying down in bed to read before going to sleep. Try to sit up with back support as opposed to lying down. If you wear reading glasses, make sure you are reading thru the proper calibrated lens area.
