Blue-filtering eyeglasses


My eye doctor urged me to wear blue-filtering glasses while I’m in front of a computer screen or an iPad screen. Though I love the Retina display on my new 27-inch iMac, the screen does seem to be — at least subjectively — more intensely blue than the screen on my old iMac. So I’ve started wearing my blue-filtering reading glasses when sitting in front of the iMac.

The concern for ophthalmologists is high-energy visible light. There is evidence that it is a factor in age-related macular degeneration. Too much blue light also may affect the brain in a way that interferes with sleep.

Adding the blue-filtering feature to a pair of new glasses doesn’t add all that much to the cost of the glasses. Notice in the photo above that the computer screen looks slightly more orange when seen through the glasses, because the blue light is reduced.

If you’re in front of computer screens a lot, and especially if you’re older, this is something worth discussing with your eye doctor.

And, of course, keeping the brightness of the screen as low as is comfortable will help preserve the computer screen, use less energy, and reduce the strain on your eyes.
