Naked eyes are not engineered to withstand staring at computer screens for hours on end, no matter how engrossed you are in your favourite game.
Eye strain from LED-emitted blue light is not the only concern; blue light toxicity and sleeplessness can also result from overuse of digital screens. But what’s a gamer to do?
Blue light and your eyes
Artificial light from digital screens is very high in the blue end of the spectrum. This blue light is close to ultra-violet (UV) light but has a slightly longer wavelength. The short-waves of UV light cause damage to the outer structures of the eye. You can see this as pterygium and cataract. Visible blue light has slightly longer waves, which penetrate more deeply into the eye and can be toxic to the delicate tissues of your retina and macula. Blue light also affects our biorhythms and makes us feel alert. Prolonged exposure to blue light, especially at night, can lead to sleep difficulties.
Eye strain and computers
Digital eye strain results from a combination of factors. Staring at screens greatly reduces our blink rate, leading to dry eye. Focussing for long periods also strains the muscles of the eyes, just like any other overworked muscle. Glare is also a significant contributor eye strain. Headaches are another common symptom of digital eye strain.
