Is Your Smartphone damaging your eyes?

Use of smartphones is on the rise. They are often looked at over 150 times per day and the use continues in the evening long after the sun has set. But how do they damage your eyesight?

Smartphones today use LED screens which emit a powerful form of blue light.

Blue light has a very short wavelength, and so produces a higher amount of energy. Our eyes’ natural filters do not provide sufficient protection against blue light rays and studies suggest that, over time, exposure to the blue end of the light spectrum could cause serious long-term damage to not just our eyes, but also our sleep patterns, increasing our risk of certain types of cancers, and putting us at greater risk of getting diabetes, heart disease and suffering from obesity.

Opticians have been warning of the risks of  blue light for many years stating that it is one the main causes of vision loss and that due to prolonged use there will be a future generation of people with major eyesight issues.

Optometrists are predicting an epidemic of premature macular degeneration (vision loss) from prolonged exposure to digital devices. A Harvard medical study states that “High Energy Visible (HEV) blue light has been identified for years as the most dangerous light for the retina.  After chronic exposure, one can expect to see long range growth in the number of macular degenerations, glaucoma’s, and retinal degenerative diseases”.  And a paper published by the American Macular Degeneration Foundation (AMDF) reports that “the blue rays of the spectrum seem to accelerate age-related macular degeneration (AMD) more than any other rays in the spectrum”.

There’s developing therapeutic proof that blue light presentation may cause perpetual eye harm; add to the pulverization 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 ingests destructive 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 powerless to eye ailment, for example, macular degeneration.

So what is the solution? Blue light Blocking Glasses are one solution. They prevent blue light from entering the eye and thus reduce the exposure to blue light related risks.
