## Description

desertcart.com: J+S Blue Light Blocking Glasses for Women Men | Anti Eyestrain Headache Glare 400UV from Computer/Gaming/TV/Phones (Haka HD lens - Rectangle | Black Frame) : Health & Household

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: Best pair I’ve tried so far - I have had these glasses for a while and they are the only pair I’ve tried so far that have worked well for me. I have tried cheap 3 pack ones that don’t do anything for me and mess with my vision because they have curved lenses or just unclear lenses. These glasses are obviously tinted and it might take getting used to as it makes everything look warmer toned. They’re more expensive than any other glasses I’ve bought but I think they are worth it. I’ve used them for hours at a time with both my computer and iPad and they greatly reduced my eye strain. Not saying it completely eliminates the issue because no matter what your eyes will be tired eventually, but this product does help prolong vision comfort.

## Questions & Answers

**Q: What's the difference between the normal and Plus models?**
A: Hello!The “Plus" model comes with High Definition Lenses. 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

**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.

### ⭐⭐⭐⭐ So . . .These Worked for Me
*by S***N on January 31, 2023*

I bought these out of curiosity. I spend way too much time on the computer, and eventually, it hurts my eyes. I remembered long ago people put shields on their desktop screens to reduce glare and wondered if there were glasses that did the same thing since I have a laptop. It turns out there are! I discovered this company on one of those "best brands" searches (which I'm always skeptical of). It was my birthday, the price was right, my curiosity high, resulting in an impulse buy. Much to my surprise, they actually work. I notice a distinct difference looking at a screen with them on; it's less painful to me. I did have to go through an adjustment period, but now I wear them whenever I'm using a device--computer, iPad, phone. My only complaint is that there's occasionally a reflection that hovers on the lenses, which can be distracting, but I've found it often depends on the lighting. Adjusting my angle or location can make it go away, but I tend to just endure and ignore it. This is the only pair I've purchased, so I can't give a fair comparison to other brands. For an impulse buy, I'm very happy with it.
