> Can anyone shed some light on whether blue-blocking coatings are actually useful/good for you?

A HN comment set me looking for some blue-blockers for night driving: https://news.ycombinator.com/item?id=14170975

My locally-owned sunglass shop stocks yellow blue blocker safety goggles that fit over my glasses. They turn obnoxious blue headlights green. I give them a 'blue headlight obnoxiousness reduction factor' of 85%.

The orange safety goggles ("uvex") I ordered from Amazon first were better (95%), but they block out too much green to be safe for night driving.

For computers, Flux (http://justgetflux.com) offers more control of blue light, and it does make a difference. Also, increase your blinking, periodically focus on distant objects (use a timer if needed) and don’t look at a bright screen in a dark room without ambient light.
