Screens, LED lights, and devices all emit blue light — and your brain responds to it the same way it responds to daylight. When you're exposed to this light in the evening, your body holds off on releasing melatonin, the hormone that helps you fall asleep. The result is that you feel wired when you should be winding down.
These glasses filter out 100% of blue light in the wavelengths most responsible for this effect (380–500nm), plus 43% of green light (500–570nm). That's a meaningful difference from cheaper alternatives that only block part of the spectrum — and not enough to actually help your sleep.
The fitover design is straightforward: they sit over your existing glasses so you don't need a second pair. A practical, affordable starting point for anyone building an evening routine around better sleep.

The reason lens colour matters is simple: amber blocks blue light, clear doesn't. But not all amber lenses are the same. Many products on the market haven't been tested to verify which wavelengths they actually block — so you can't be sure they're doing enough.
The SunDown amber lens in these glasses has been independently tested to confirm it blocks the full range of sleep-disrupting light. The lighter tint also means colours still look reasonably natural, making them easier to wear while watching TV or reading in the evening.

Put them on about 1–2 hours before bed, especially if you're using screens or sitting under bright lights. Wear them consistently each evening — your sleep will improve most when it becomes part of a regular routine rather than something you do occasionally.
