Light from smartphones could cause premature blindness

In today’s society we are all constantly using our smartphones. They are very much part of everyday life. We use them for work, pleasure and even as cameras. We look at our phones up to 150 times per day on average. For many of us they have replaced our televisions and it is not uncommon for many to watch full feature length movies from their small screens late into the night.

The sight of seeing whole families at a restaurant table all glued to the phones and ignoring each other is also a common sight, but despite their uses smartphones have a dark side to them.  Smartphones today use energy efficient and bright LED screens. These screens emit a powerful form of light wave called blue light which studies reveal to be the most damaging form of light to the retina. Too much exposure to Blue Light can result in both digital eyestrain and long term damage to a persons eyesight.

 

There’s developing medical confirmation that blue light presentation may cause perpetual eye damage; add to the annihilation of the cells in the focal point of the retina; and assume a part in causing age-related macular degeneration, which can prompt vision misfortune.

Melanin is the substance in the skin, hair, and eyes that retains unsafe UV and blue light beams. It’s the body’s normal sunscreen security. Higher measures of melanin bear the cost of more prominent insurance, yet as we age we lose melanin, so that by age 65 half of the security is gone making us more defenseless to eye sickness, for example, macular degeneration.

The retina is a thin, multi-layered tissue covering the internal eyeball. The retina can be hurt by high-energy visible radiation of blue/violet light that infiltrates the macular shade found in the eye. A low macular shade thickness may speak to a hazard factor for age-related macular degeneration by allowing more prominent blue light damage to the retina.

A Harvard medical examination expresses that “High Energy Visible (HEV) blue light has been distinguished for quite a long time as the most unsafe light for the retina. After incessant presentation, one can hope to see long range development in the quantity of macular degenerations, glaucomas, and retinal degenerative diseases”. What’s more, a paper distributed by the American Macular Degeneration Foundation (AMDF) reports that “the blue beams of the range appear to quicken age-related macular degeneration (AMD) more than some other beams in the range”.

So what are the solutions to this growing problem of over exposure to blue light? One option is the use of non-prescription eyewear with orange coloured lenses like the type once used by NASA astronauts. These blue light blocking glasses work by allowing all other forms of light to enter the eye while blocking out the harmful blue light. They improve vision and picture clarity and ultimately protect the eyes.
