The honest version
Most Blue Light Glasses Are Clear
You have probably seen the headlines saying blue light glasses do nothing. Those studies are real, and they tested clear lenses, the kind that block very little.
A randomized trial on properly tinted amber lenses found something different: about 30 minutes more sleep, and less insomnia. Those lenses blocked 65 percent of blue light.
Lucerna is tinted, and it is built for the evening rather than your whole workday.

The Questions Worth Asking
Depends what you mean. For eye strain the honest answer is that the evidence is weak, and we are not going to pretend otherwise. For sleep it is better: trials on tinted amber lenses worn in the evening found more sleep and less insomnia. That is what these are built for.
Because blocking blue light means removing blue from what reaches your eye, and removing blue is what makes a lens look warm. A clear lens cannot block much without changing colour. The tint is not a style choice, it is the mechanism.
The yellow pair reads as an ordinary tinted lens and most people wear it out of the house. Red is stronger and most people keep it for home in the evening. That is why there are three.
No. They are non-prescription and do not correct vision. They are built to sit comfortably over long sessions at a screen.
