Ophthalmology & Optometry/Essilor and blue light


QUESTION: Hi Mr. Sobotor, I'm looking for eyeglasses that block blue light so that light at night won't affect my sleep. I read that the Essilor sells  that blocks blue light allows "beneficial blue light". Does that beneficial blue light affect sleep?

ANSWER: Hashem,

You pose a very timely question. There has been a great deal of information printed about blue light and its potential harmful effect on the human eye. There are many companies now making products that address blue light so your options are increasing.

The "beneficial blue light" is blue light of lower energy. It represents the majority of the blue colors in the visible spectrum. You want exposure to that for, among other things, good balanced color vision and to help regulate you sleep cycle. So wearing lenses designed to filter that type of blue light will allow in what is needed but not the harmful light or light that can disrupt your sleep cycle.

Another thing to note is that computer use, video game play, and other similar electronic devices should be stopped a few hours before going to sleep. These devices emit light that can cause disturbances in your sleep cycle. I actually sell a "gamers" lens that filters that light out and use it even if there is no prescription needed.

QUESTION: I try not to use my laptop 4-5 hours before sleep. However,I intend to use these glasses if I have to go somewhere at evening/night that has lots of artificial light, especially LED light, like the TV room. Am I better off with a lens that blocks the beneficial blue light or one that blocks it if I only use the glasses in the few hours before bed time?


If I understand your question, "Should I wear the blue blocking lenses all day or just at night when I am going to be in a lot of artificial light?" my suggestion would be to wear them all day. Many people report more comfortable vision and a reduction in stress around the eyes that was not noticed prior to wearing the lenses.
