Blue Light Glasses NZ to Protect Your Vision and Help You Sleep
Most of us are spending a lot more time in front of screens than we probably should be, and the eyes tend to feel it first. If you're a professional, a student, or someone who watches a lot of TV in the evening, blue light glasses are worth looking into. They filter a significant portion of the high-energy visible (HEV) light that comes off screens, tablets and phones, the stuff that contributes to eye strain, headaches and disrupted sleep.
Why Blue Light Affects Your Sleep
Here's the issue with screen time in the evening. Blue light interferes with melatonin production, which is the hormone that tells your body it's time to wind down. Less melatonin means it takes longer to fall asleep, and when you do, the quality isn't as good. It's a small thing that adds up over time, and it's why a lot of people who start wearing blue light glasses in the evening notice a difference within the first week or two.
Our blog goes deeper on the science if you're interested. How circadian rhythms and light exposure affect your sleep is worth a read.
Who Should Wear Blue Light Glasses
The short answer is anyone spending three or more hours a day on a screen. That covers most office workers, students, gamers, and people who wind down with a phone or tablet before bed. A number of professional athletes have also added blue light glasses to their recovery routines for the same reason. Better sleep means better recovery, and it's one of the easier habits to build. No magnification is needed, so anyone can wear them straight out of the box.

What to Look For in Blue Light Glasses NZ
Not all blue light glasses are equal. Look for lenses that filter HEV light in the 400-450nm range, where the most disruptive wavelengths sit. A clear or very lightly tinted lens is fine for daytime screen use. Comfort matters too, especially if you're wearing them for hours at a time. The iPOP range uses flexible steel hinges for a comfortable fit across a range of face shapes, and every pair comes with a free microfibre soft case.
