Four frame colours, three lens tints, one price.\u003c\/p\u003e\n\n\u003ch2\u003ePick your lens by the time of day\u003c\/h2\u003e\n\u003cp\u003eTint is the whole decision. A warmer, darker lens cuts more of the blue and blue-green range, which makes it better for the evening and worse for anything where colour accuracy matters. All three lenses are available in every frame.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eYellow — daytime screen work.\u003c\/strong\u003e The lightest filter of the three. Takes the edge off glare and long monitor sessions while keeping colours close enough to normal for everyday work.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOrange — evenings.\u003c\/strong\u003e A stronger filter for the two to three hours before you want to be asleep, when blue-rich light from a TV, laptop or phone is most likely to push your body clock later.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRed — late nights and shift work.\u003c\/strong\u003e The heaviest filter, for night shifts, reading in bed and 3am wake-ups. Colours shift noticeably, which is the point: red is for winding down, not for accurate work.\u003c\/p\u003e\n\n\u003ch2\u003eFrames\u003c\/h2\u003e\n\u003cp\u003eGrey, black, tortoise and clear, all in the same lightweight design and all available with any of the three lens tints.

Short-wavelength light in the evening is a well-established signal that delays melatonin release, and filtering it is a low-risk thing to try.\u003c\/p\u003e\n\u003cp\u003eThey are less convincing as a fix for digital eye strain. Most eye-care bodies now attribute screen fatigue to prolonged focusing, glare and reduced blinking rather than to blue light itself — so breaks, screen brightness and blink habits will do more for tired eyes than any lens will.\u003c\/p\u003e\n\n\u003ch2\u003eCommon questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eDo these fit over prescription glasses?\u003c\/strong\u003e No — they are standalone non-prescription frames, not fitovers.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I drive in them?\u003c\/strong\u003e Yellow lenses are fine in daylight.
