Modern day electronics, from your stove, to smoke alarms, to your TV, all have indicator lights or small displays. However, they’re also small sources of junk light that disrupt the sleep/wake signals sent to your brain; impacting your sleep, your mood, and your growth hormones. The old-school way to handle blocking out these sources of junk light was to use something like black electrical tape that covered displays that you need to see, looked ugly and left a sticky mess when removed. TrueDark Junk Light Dots are reusable adhesive stickers designed to block the harmful light frequencies that impact your biology, while keeping display visible. They come in conveniently shaped round dots in 2 sizes that cover most light emitting buttons (such as the one on your TV or wireless router), as well as small squares and rectangles for things like the digital display on your stove and microwave.
