The discomfort some people have after looking at screens is most likely\u00a0digital eye strain. Most of us blink less when looking at screens,\u00a0causing eye strain and dry eyes, says Rahul Khurana, MD, a spokesperson for the American Academy of Ophthalmology. The good news is eye strain does not cause lasting damage and is easily preventable.\u00a0
The best way to\u00a0protect your eyes against eye strain\u00a0is to take regular breaks using the “20-20-20” rule: every 20 minutes, shift your eyes to look at an object at least 20 feet away for at least 20 seconds. You can also use\u00a0artificial tears\u00a0to refresh your eyes when they feel dry.\u00a0
Skip the glasses that claim to protect your eyes against blue light, because of a lack of evidence that they are effective. The Academy does not recommend any special blue light-blocking eyewear for computer use.<\/p>\n\n\n\n
Blue light does affect the body\u2019s circadian rhythm, our natural wake and sleep cycle. During the day, blue light wakes us up and stimulates us. But too much blue light exposure late at night from your phone, tablet or computer can make it harder to get to sleep.
That is why Dr. Khurana recommends that you try to limit your screen time in the two to three hours before you go to bed. You can also try\u00a0nighttime settings\u00a0on your devices to minimize blue light exposure in the evenings.<\/p>\n\n\n\n
Although people often associate blue light with computers and phones, the largest source of blue light is sunlight. Other sources include fluorescent light, compact fluorescent light bulbs and LED light. Blue light exposure from screens is much less than the amount of exposure from the sun. It’s also no more damaging than blue light from the sun, Dr. Khurana says.
Too much exposure to\u00a0ultraviolet light from the sun\u00a0increases the risks of eye diseases, including cataracts, growths on the eye and cancer. We know less about blue light. Its effects are still being researched.
Some studies suggest that\u00a0not enough exposure to sunlight in children could affect the growth and development of their vision. Not getting enough sun could also increase the risk of myopia (nearsightedness) in teens and young adults, a\u00a0recent study\u00a0suggests.
The bottom line, Dr. Khurana says, is that taking preventive measures against blue light even though there is no evidence of damage could be more harmful than the blue light itself. \u201cIt\u2019s premature to take preventative action against blue light\u2014there could be unintended consequences,\u201d he says.<\/p>\n\n\n\n
