Affordable UK-made blue blockers for the evening, with amber (evening) and red (night) lens options that block blue plus green — the wavelengths that actually suppress melatonin. Prescription available. Not the most stylish frames, but the filtering is honest and the price is fair.
Anyone wanting an evening/night wind-down block without paying premium blue-blocker prices.
Daytime wear — amber and red lenses in daylight distort colour and cut useful light.
