About Spectra479
Spectra479 is a small, family-run eyewear brand built around a single idea: controlling your light exposure in the evening changes how well you sleep. The company's product range centers on amber and orange lens glasses meant to be worn in the hour or two before bed, alongside clip-on lenses, fit-over frames for people who already wear prescription glasses, a higher-end handmade-in-Japan line, and a kids' line of blue-light-blocking glasses.
What sets Spectra479 apart in a crowded category is that it actually states a wavelength range for its blocking claims, something most blue light glasses listings on Amazon skip entirely. The brand says its amber lenses are tested to block 99.9% or more of light between 280 and 510 nanometers, the band most associated with suppressing melatonin production at night. Its fit-over design, built to slide over an existing pair of prescription or reading glasses, is a practical answer for the many buyers who don't want to pay for a second prescription pair just for evening screen use.

Fit-Over Amber Blue Light Blocking Sleep Glasses For Prescription Glasses
In our testing, this is the pair we point glasses wearers to for evening screen use: the amber lens fits directly over a prescription or reading frame, so there's no need for a second prescription pair just for nighttime. Spectra479 states the lens is tested to block 99.9% or more of light between 280 and 510 nanometers, the range most tied to melatonin suppression, and the wraparound shape limits light leaking in around the edges of the glasses underneath. One pair covers phone, tablet, laptop, and TV use once the sun goes down.
