The experience of eye strain when reading in dim light has given rise to the common misconception that such an activity causes permanent eye damage. [3] When concentrating on a visually intense task, such as continuously focusing on a book or computer monitor, the ciliary muscles and the extraocular muscles are strained. This causes discomfort ...
This, unaware to them, causes the eye strain to build up over a period of time, when if they had obtained seven to eight hours of uninterrupted sleep, their eye muscles would have recovered during the sleep and the strain would not have built up. [citation needed] Computer workers are often advised to take breaks and look at distant objects. [4]
“Luckily, eye strain is temporary,” said Raj Maturi, an ophthalmologist at Midwest Eye Institute in Indianapolis who serves as spokesperson for the American Academy of Ophthalmology. “The best way to avoid these symptoms is by taking breaks from our screens or near work activities and using lubricating eye drops, if needed.”
Reading glasses should also be used every time you read your phone, books, magazine, or newspaper to prevent eye strain, says Dr. Cho. “This strain can cause headaches and blurred vision ...
This is the major reason that eyes dry out and become fatigued when reading. When the eyes dry out or become fatigued due to reading on a computer screen, it can be an indication of computer vision syndrome. Computer vision syndrome can be prevented by taking regular breaks, focusing on objects far from the screen, having a well-lit workplace ...
A whopping four in 10 millennials spends at least nine hours on a digital device each day.
Blue light, a type of high-energy light, is part of the visible light spectrum. High-energy visible light (HEV light) is short-wave light in the violet/blue band from 400 to 450 nm in the visible spectrum, which has a number of purported negative biological effects, namely on circadian rhythm and retinal health (blue-light hazard), which can lead to age-related macular degeneration.
Systematic reviews have highlighted the association between blue light exposure and digital eye strain. [11] [23] Digital screens emit significant amounts of blue light with shorter wavelength and higher energy compared to other visible light, which can cause symptoms such as eye fatigue, eye dryness, blurred vision, irritation, and headaches.
