Are Computer Glasses Necessary??

May 10, 2017

As many of us now spend several hours of our day on computers, many ask if computer glasses are necessary?  After our mid 40's many of us may need special glasses to focus on the computers to offer some magnification, just as we may need reading glasses.  However eyeglasses that claim to filter out blue light from computers, smartphones and tablets are becoming increasingly popular. Ads for these glasses claim overexposure to blue light can cause a number of problems. The problems supposedly linked to blue light range from dry eyes to digital eye strain, sleep cycle disruption and even macular degeneration, which causes people to lose some or all of their central vision. However there is no evidence that the kind or amount of light coming from computer screens is damaging to the eyes.  The American Academy of Ophthalmology does not recommend any special eyewear for computer use at this time.
