TrueDark by Dave Asprey | Daylights Yellow Lenses Block 75% of Blue Light for Heavy Daytime Screen Use

The best on the market. Comfy and flexible enough for an adult head as opposed to the cheap Chinese ones. My old pair lasted a decade.

I wasn't sure they would work as I suffer from headaches and dizziness when working at a screen all day and I also struggle to focus, these have solved all 3 ussues however for the first week I did get some random headaches but they stopped after the first week. I would recommend these glasses however they are not to be used outside. A game changer and i am grateful for ones that actually work.

Excelente, siento más descansada al vista al usarlos y no me lastima los ojos al estar frente a la computadora, son muy cómodos y la atención fue excelente

I was surprised by how remarkably well these glasses worked. The effect was immediate and I noticed a significant reduction of eye fatigue while working on my computer. The frame is also of good quality, which I appreciate. I am a shift worker by trade and I am excited to see how these will work in combination with the twilight glasses (of which I also purchased a pair) in helping to blunt the effect of bright florescent lighting/computers/headlights at night on my circadian rhythm. I can definitely say that I notice a bit of a, for lack of a better term, "head change" while wearing them. I would describe it as a similar to being outdoors as the sun goes down and the environment transitions to the dark of night. Kind of a slight drowsiness. Just my subjective experience, and it goes away as soon as I remove them under florescent lighting. I'm certainly going to log more time with them before I consider whether or not to drive with them on.. I have had my eyes on these for several months (pun intended), but was hesitant due to the price. The reduction in eye fatigue while working on a computer screen was worth the price alone. I'm wearing them even as I write this review.

Been using these glasses for a few months now. I was hesitant to buy as they are expensive. However, I have bought several other blue light blocking glasses now, including other expensive / well known brands. The other brands are fine to watching a move before going to bed, or casual wear, but they are not great if you want to spend of lot time/all day on the computer to protect your eyes. I have to say, the quality is very good. The frames are truly superb. If looked after, the frames would last a life time. And I can wear these all day using a computer without any negative impact. They are not dark enough to be a problem with changing colors or impacting brightness. They are crisp and clear (no distortion of vision which you can get with other blue light glass). I can leave the computer and walk around the house/office and leave them on. With other blue light glasses I would be inclined to take them off. I do believe that my eyes are less tired and I feel less drained at the end of the day, so they seem to work as advertised. Overall, I feel these are worthy investment and I have no regrets buying them. I'd prefer it they were a little less expensive, but would buy again.
