We spend a great deal of time staring at screens. If it’s not that of a computer, it’s a tablet or smartphones. In the past, there was no wondering if it was bad for our eyes. Now, there’s a lot more talk about blue light. Even in the media…
Studies have proved that a prolonged exposure to this type of light can cause serious – even irreversible – damage to our eyes. And, sadly, computer screens are not the only source of blue light. Blue light is present in several artificial lighting sources such as digital screens like televisions, tablets and smartphones. It can even be found in natural sources such as sunlight.
Even though short-term exposure without eyeglasses will cause visual discomfort or fatigue, long-term exposure can accelerate and aggravate conditions such as age-related macular degeneration and cataracts. Aside from ocular health, blue light has a detrimental effect on sleep and can cause problems such as insomnia.
Limit the time spent in front of screens – Avoid using your tablet or any other screen before going to sleep and, more importantly, do not spend more than two consecutive hours in front of a digital screen.
Adopt healthy habits – When you work in front of a computer screen (or any other type of digital screen), maintain a safe distance (around 60 cm) and decrease its brightness to minimize glare. In addition, blink more often. Practice the 20/20/20 rule: take a break each 20 minutes and look at 20 feet in front of you for 20 seconds. This helps reduce eye dryness and fatigue.
Crizal Prevencia treatment – There is a type of lens (not contact lenses) that blocks out that evil blue light. Lenses benefitting from the Crizal Prevencia treatment prevent the premature ageing of your eyes by selectively filtering out that harmful light frequency.
- They reduce exposure to blue-violet light, thus considerably lengthening the life of retinal cells.
- They provide a better UV ray protection than an unprotected eye. This protection against UV rays is more complete than that offered by untreated lenses.
Transitions Lenses – Transition lenses help shield the eyes from the blue light under any condition. Indoors, Transition lenses protect eyes from the blue light emitted from artificial sources such as digital devices and LED lights. Outdoors, they provide an additional protection from sunlight by protecting the eyes from glares, intense blue light and UV rays.
