Review: High quality glasses! - Delivered on time, seller contacted me via email and explained a few more things about the item before it arrived. It does come with a carry case to protect it. Haven't used it much yet but will update this as I use them. Upon initial inspection, they seem to be high quality, very light weight material. I have a big head and cheaper glasses will break if they don't fit, however these were able to stretch far enough to fit me and not break or even feel like they're going to break. They are not NEARLY as yellow as the picture makes them look, so plus there because I won't look like a weirdo wearing them. They almost look like just regular glasses,I'm eager to try them out as an avid gamer and see if they help with eye strain, eye drops just don't cut it at a certain point. First impressions were very good so far so I'm hopeful they perform as well as they look and feel. Also the case they came with is extremely nice, also came with a microfiber cloth for cleaning. The case almost feels like a hard plastic but I didn't play with the case as much as I did the glasses, so will update in the future! Update: since I've gotten a chance to use them now, I can say these help a lot. They aren't going to 100 percent stop eye strain, but they are definitely helpful. The yellow tint isn't enough to ruin quality at all, they're comfortable and light weight, and most of all I went to bed without bloodshot eyes lol. I'd definitely recommend for anyone who is focusing on a screen for long periods of time, gamer or otherwise. Again though, you still can get eye strain, so take breaks when you start to feel it, you just won't have to take as many with these. I went from a 20 minute break every 2 hours, to only one 30 minute break throughout the whole session! Review: Save Your Eyes and Buy - I game for 6 hours roughly every other day. These glasses have helped me stop getting headaches from long periods of staring at a screen. I also use them at night as well near bedtime. By eliminating the amount of blue light at night, I found myself being able to fall asleep quicker after turning off my computer screen. ## Features - [Experience Relief with Blue Light Glasses]: non-prescription glasses that filter out high-energy blue light from electronic devices, including computers, TVs, smartphones, and even fluorescent lights.

The High Definition Lenses offers:   - significantly reduced reflection/glare especially under low light conditions   - a higher level of protection - blocks more harmful blue light   - a darker yellow tint (higher color distortion)The Plus models (High Definition Lenses) are more suitable for heavy usage, intensive gaming sessions, and for viewing screens in low ambient light conditions. The standard models (Low Color Distortion Lenses) are great for general office work in good ambient light conditions.We'll include a detailed comparison in the product info later on.Regards,J+S Vision **Q: Is the high definition lens - glossy black frame a different shape/size than the low color distortion lens - matte black frame?** A: Hi! The SIZE selector selects the frame shape and size that you like. The COLOR selector allows you to pick the lens option and color of the frame. For example, the following 3 "Classic Rectangle Frames" variations combos would all come in the same shape and size: Variation 1) SIZE: Classic Rectangle Frame + COLOR: High Definition Lens - Glossy Black Frame Variation 2) SIZE: Classic Rectangle Frame + COLOR: Low Color Distortion Lens - Matte Black Frame Variation 3) SIZE: Classic Rectangle Frame + COLOR: Low Color Distortion Lens - Glossy Tortoise Frame Hope this helps. Please let us know if you have any other questions. Cheers @JandSVision **Q: "the bls would be what you want" could you send a link for bls? (how to choose bls, where are they?)** A: Hi! Sorry I'm not too sure what your question is. Did you want help selecting a suitable Blue Light Shield lens? If so, you may find the lens comparison table in the product images section. Here's a direct link to the table for your reference (https://images-na.ssl-images-amazon.com/images/I/610v4N7UWtL._SX522_.jpg). Hope this helps. Please let us know if you have any other questions. Cheers @JandSVision **Q: does the High definition make your vision sharper?** A: It won't fix or correct your myopia, but at least for me I feel my vision is still sharper after hours behind a monitor because the filter prevents your eyes from getting tired. ## Customer Reviews ### ⭐⭐⭐⭐⭐ High quality glasses! *by H***Y on February 18, 2018* Delivered on time, seller contacted me via email and explained a few more things about the item before it arrived.

By eliminating the amount of blue light at night, I found myself being able to fall asleep quicker after turning off my computer screen. ### ⭐⭐⭐⭐ Worth the price, cute, light, and does what it says it does. *by D***S on July 27, 2017* These are pretty cool. I am actually wearing it now. It has helped with my eye strain. I stare at a computer all day at work so I wanted to try a pair of inexpensive computer glasses. These are really light and pretty cute too, makes you look extra hipster and nerdy. Hahaha. My fiance has the Gunnar glasses and he said these are pretty good compared to the Gunnars, they get rid of the blue light in the screen and it's really noticeable. There's a a slight yellow tint to them, which I think helps the blue light in the screen. One thing I don't like is that it has a very very strong glare and it's very reflective. Wish it had anti reflective screen on it. Overall, it's worth it for the price. I'm sure they won't last a lifetime but hey, they were cheap. And it's nice that it came with a hard case and a wipe! It's the little details.. 😁 ## Frequently Bought Together - J+S Blue Light Blocking Glasses for Women Men | Anti Eyestrain Headache Glare 400UV from Computer/Gaming/TV/Phones - J+S Blue Light Reading Glasses for Women Men | 3 in 1 Readers Block Harmful Blue-Light 100% UVA UVB | 1.0+ to 3.0+ Diopter - Stylish Blue Light Blocking Glasses for Women or Men - Ease Computer and Digital Eye Strain, Dry Eyes, Headaches and Blurry Vision - Instantly Blocks Glare from Computers and Phone Screens w/Case --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/43286637-heavy-duty-lens](https://www.desertcart.pl/products/43286637-heavy-duty-lens) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-10*
