Digital Screens and Retina Damage?
A new topic for eye doctors and opticians is the explosion of new screens which most people are staring at these days – smart phones, tablets, desktop monitor, LED TV’s . . . . . and people are gazing for hours at a time compared to in the past.
The problem is that these screens operate with blue light as the background color – and although you might think that it’s not really blue I assure you it’s true: if you’ve seen a kid on your street at night with a smart phone you’ll agree that the glare off their face is bluish – not green, not yellow, not reddish but actually blue. Blue light has the ability to smash into the eye with wavelength power perfectly tuned to concentrate on the retina in a avalanche of excess and over time cause retina damage – it’s a big downside of this modern world we live in now. What condition will the retinas of the world [and your retina too] be in down the road in 10 years or so – especially when retinas are supposed to last for 100 years in normal use.
The brain / body needs some blue wavelength light onto the retina receptors to maintain mood and a normal diurnal body rhythm so filtering out all the blueness from the sky or computer LED workscreen would be bad. The trick is to eliminate mostly the harsh blue parts.
At Family Vision, our whole concern about this new information has evolved – and that’s why new lens filters are now available, and beneficial and important – just ask for the Crizal Prevencia lenses for your next new eyeglass prescription at your next visit here.
