These are awesome, blue light blocking glasses. It says 70%, but that must be much more then all of the others with clear lenses that I’ve been trying, which are cheaper to buy, as my eyes feel more of a difference in these. The getting used to part is the yellow- tinted lenses. It makes everything look crisp & clear to me.. but obviously, yellow. I’m typing in them right now. Once you adjust to them, the yellow stands for gold!!I have daily strained, chronically dry eyes that are always red & veiny looking ?. No doctors have been able to help me to date. Started during Accutane use 13 years ago… working online does anything but help the situation. I spend hours on video editing, writing reviews, writing blog posts and poetry, and posting on social media. Everything I do is based on my computer & my cell phone. My eyes have taken the hit.. HARD! They seriously could not get any worse.I never saw a percentage put on a blue light blocking set of glasses, but this one must be highest, well, at least of any typical ones, because I feel an ease in the strain over the past 10 days. I don’t wake up AS bad as I normally do. I haven’t needed to pry my lids open to put my drops in for like 4 or 5 days now. No other changes have been made & the weather is colder, so that’s when I get even worse.Right now, how can I not sing this product’s praises??? ?‍♀️ I got to! These might be good driving at night in my car, too. Since my problems started, the lights on cars have really caused me issues to where I barely ever drive at night. I could see how these might be beneficial at toning down the car headlights that are heading in my direction. I’m going to try that. It would make sense.This is packaged incredibly. I mean.. better then any pair of $300 glasses from the eye glass store. The name is a bit weird, but that isn’t any issue. BUT this isn’t just ‘any gift’ lol.. if you struggle with dry eyes and strained, tired eyes & use devices for long periods of time, I highly recommend these for you, or someone you love.The frames are sturdy, not cheap. Not super light weight, not heavy & annoying. Just right. They WILL last, so the price is very fair, and the case is a pro case. It will keep your glasses perfectly preserved through the years. It comes with a pouch and cleaning cloth, too! What a deal, right???I’m happy with these. Give yourself a few days to adjust. I almost got dismayed at first, but I’m happy I stuck with them. I do believe that you’ll see and feel the difference, too. I swear I’ve had fewer headaches, too.. and no, my kids have been more wild then ever, so that’s not it ?.Buy ‘em, try ‘em! You can always return them, if they are not for you. I had to share my positive experience with the world, as I know I’m far from alone.5+ stars!⭐️⭐️⭐️⭐️⭐️** I hope my review is helpful ?. **These glasses come with a microfiber cloth, in a drawstring baggie, in a nice little hard snappy case, in a multi-layered box... and everything is branded "Any Gift" Oh right, that's also in the packaging box, which is also branded and looks nice.As for the glasses they're pretty standard plastic feeling glasses. Black frames, yellow lenses, silverish hardware for the hinges.Definitely a nerd vibe on the look. I kinda dig it. My kid keeps trying to steal them because she thinks they're fab.Microfiber cloth is pretty standard. It's passable and doesn't appear to shed on the lenses.The hard box is decent. It's probably a lot cheaper than it feels. I actually thought it was hard wood for a second before I examined it to write this review. It's one of those boxes that SNAPS shut when you go to close it. I feel like it's sturdy enough to take a hit and save the glasses.The bag is fine. it fits over the box almost perfectly.The box is totally presentable, but seriously how many storage devices do you need for these things? 2 boxes and a bag? It'll get super annoying just retrieving them if you use all 3. But to be fair they really do an AMAZING job selling you on what a cool gift this would be. I was unusually delighted while opening these up.As for the blue light filter effect, it's there? I cannot tell if it's helping. Things do get dimmer and everything takes a yellow tint. Blues become more green and whites become yellow, that sort of thing. My eyes feel a little off adjusting, but honestly I just haven't had any mega long gaming sessions to determine if they ease the eye strain.Fun fact: when I tilt my head sideways the yellow tint clears up entirely. I feel like I learned the science behind that before, maybe something to do with how the filter is polarized or something. It's neat though.Overall they aren't super expensive. They might make a super cool gift for someone, and even if they don't fall in love with them they'll likely have no issue regifting them. Heck some people would love them just for the aesthetics. Yellow-lens nerdiness for the win!
