Amber-lensed glasses from BlockBlueLight that filter blue light from screens. The SunDown lens is claimed to block 99% of blue light between 380 and 500nm and 43% of green light between 500 and 570nm, so it tints the view amber rather than clear. That makes it a night-time pair for evening screen use, not an all-day clear lens. Buyers rate it highly, and the main trade-offs are the strong amber tint and the fact that it is not made for people who wear prescription glasses.

Buyers rate these highly and many say they help with evening screen time and sleep. The most common complaint is the noticeable amber tint and the look of the frames.
These blue light blocking glasses use the SunDown Amber Lens. The lens blocks 99% of blue light from 380-500nm and 43% of green light from 500-570nm from electronic devices, without distorting vision.
The frame has a wrap-around fit that reduces artificial light leaking in from the sides. The arms are flexible and adjustable. The glasses come in packaging with detailed information about blue light.
A separate FitOver version is available for people who wear reading or prescription glasses.
