A couple of weeks back I received this lovely pair of Cat Eye style THL Sleep blue light blocking glasses in my mailbox, as a gift from it’s designers. I’ve been using the pair just about every evening since I received them, and here’s what I think so far.

Long story short, I love them.

In the past couple of years I looked into quite a few of the blue light glasses that popped up in the market, and I generally wasn’t a fan. While the idea is pretty important and I definitely did feel the need for a pair, it seemed like not much time was spent on the design and details of even some of the most pricy pairs out there. Mostly I just wasn’t a fan of the frames. From some harsh nose pads and temple tips to the kind of weight that wouldn’t allow the pair to stay still on the top of the rather smooth curve of my nose bridge. On the other hand the polarised and battery powered ones created issues with polarised screens, and a whole heck of a lot of them come without UV protection which is not a great idea since you may still want to be wearing the glasses while outside and while there’s still sun in the sky.

Then I had a chance to speak with one of the founders of the Swedish THL Sleep, and it turned out they’re designing and producing blue light glasses that actually address pretty much all of the issues I have with the rest of them!

The Cat Eye pair I’ve received are lightweight, super comfortable and quite pretty, and from what I’ve seen on their website, it seems to me like the same can be said for the rest of their designs. Without being polarised, they manage to filter out 99,5% of the blue and over 70% of the green light spectrum. The glasses come with anti-glare coating, and offer full UV protection. And I have to say I’m quite happy with the effects of wearing the glasses. While exposure to blue light has never had any effect on my sleep, I definitely feel that my eyes get far less exhausted after many hours of staring at screens.

The real pity is that with all the digging I did for a suitable pair of blue light glasses, I never actually came across THL Sleep, until I was directly told about them. The one company that’s producing such glasses in great quality, and there’s hardly any information about them out there. So if any of you biohackers et al are looking for a nice practical pair, do check these guys out.
