I've been reading that many of us suffer from light sensitivity especially under some artificial light sources. Though I need more light as I get older, some indoor places make me feel anxious and I feel the need to wear dark glasses outdoors on bright days.
Well my dental assistant told me that she began having headaches at work a few years ago. She found out about lenses that block the blue light and got some. She doesn't need glasses for vision issues but did need to wear some sort of eye protection at work. So she got some frames she liked and had blue-blocking glass put in them. Her headaches went away. The lenses look clear so you wouldn't know they aren't regular glasses.
I'm going to try some as soon as I need new glasses, maybe sooner. I'll let you know how they work, what they cost etc. I think I saw this option on Zenni.com where I got my last pair.
