Digital Eye Strain (Computer Vision Syndrome)

Eye strain from digital device use

Digital Eye Strain (DES) or Computer Vision Syndrome (CVS) is a common condition seen in people working with digital devices. Symptoms are those related to eye muscle strain and fatigue (like eye ache and tired eyes, headache behind the eyes, blurred vision, and difficulty focusing) and those related to drying of eyes (like eye irritation, excessive tearing, and redness of the eyes). Several factors are responsible for digital eye strain. These factors can be corrected or their effects can be minimized by measures like using the 20-20-20 rule, using lubricating eye drops, blink training, increasing intake of omega 3 fatty acids, avoiding the use of contact lenses, correcting errors of refraction, reducing nicotine use, optimizing monitor distance and placement, increasing screen resolution, using good screen contrast, using certain types of fonts, avoiding small font size, using an anti-glare coating on devices, and certain other measures.

Effects of Blue Light on Health (Sleep, Eyes, Depression, and Dementia)

Blue light is a part of the visible light spectrum. Sources of blue light include the sun, screens of digital devices, and bulbs. Blue light inhibits melatonin secretion and consequently disrupts sleep. In current times, widespread and excessive use of digital devices has contributed to sleep problems, and consequently, other harmful health effects. Blue light can also cause retinal damage in the eye (known as Age-related Macular Degeneration or AMD). Blue light effects can be reduced by taking a diet rich in anti-oxidants, using blue light filtering glasses, reducing illumination on digital devices, using dark themes, using night-mode or night-mode apps, and minimizing the use of digital devices to the bare minimum. Blue light is also responsible for daytime sleepiness in the elderly. Finally, blue light is not always bad. Blue light increases alertness, improves memory and mood, and can help in synchronizing sleep in night-shift workers, people working in the aviation industry, and patients with sleep disorders. In this article, we explain all this with the help of the available scientific literature.
