Review: There is a limit to the size glasses these will fit over. - I bought these glasses because I was bothered by the side flashes coming around my Philips 202 visor lenses, the ones I use for most of my smaller COE 104 glass projects. I paid full desertcart price for them and this is not a paid review. These glasses are roughly similar to my WaleWear "Lampworker Combo" glasses with the WaleWear flip up lenses in the down position. However the WaleWear design is for the main glasses to be just a little darker than 202 didymium with attached flip up W3 lenses but the VetroSafe is a main lens which is W3 and no flip up. This leaves open the possibility of adding a W5 flip up to the Vetrosafe glasses later, if I can ever find one for sale. (I will leave it to the reader to make their own comparisons of advertised spectral specifications from the Wale Apparatus site.) On the Vetrosafe website the maximum size glasses these safety glasses reportedly will fit over is 135mm x 45 mm. Which irritates me a bit since my favorite computer glasses are 138 mm wide! That having been said these are comfortable and fit over my spare glasses, which are 132 mm wide. Still, reviews are subjective so size is where the four instead of five star rating comes from. Referring to the Guide to Safety Ratings for Lampworking Glasses on their website and to the desertcart information listed on their product page the seller reports they are in compliance with ANSI Z87.1-2020 W3.0 standards. As their website explains, that means a transmission rate of 15% of visible light, The website also reports 95% IR filtering (R4) and 99.9999% UV filtering (U6). They do indeed block the yellow sodium flash as well if not better than my Phillips 202 visor, but I'm not sure how to quantify that, especially since light tends to reflect around the edges of the visor, but not the edges of these glasses. I really can't tell about blue since my blue glass rods appear to be easily identifiable when looking through these glasses. The torch flame appears about the same, maybe a bit less intense blue but I can't tell one way or another, since the hot beads tend to make the color of the flame dim by comparison. I also appreciate the storage case included with the glasses, which means I can store my spare computer glasses with them in my glass shop.
Review: Great, lightweight glasses. 2nd pair I've purchased. - This is the second time I purchased these. I bought a pair back in 2023. I like them so much because they fit securely over my Rx glasses and are very lightweight compared to many glasses I've used in past years. My first pair (2023) lost the pin to the right ear piece somewhere along the way. Easily fixed by my husband with a small piece paper clip. They're still going strong but I decided to treat myself to a new pair and keep the 2023 pair for friends and customers who like to watch the live show. These are great glasses at a fair price. Do not hesitate to purchase them, I don't think you would be disappointed.

## Features

- UPGRADED FRAME MATERIAL: Frame material upgraded to Grilamid TR-90 for improved resilience against cracks, heat and solvent exposure.
- DIDYMIUM-ALTERNATIVE POLYCARBONATE LENS: Traditional didymium glass lenses are heavy and do not have sufficient protection against infrared and blue-light without extra welding shade lenses, adding weight and bulk. VetroSafe's VSF-3.0 Shade 3 lens provides equivalent functionality to didymium lenses with improved impact resistance, and lower weight thanks to its optical-grade polycarbonate base.
- FOR SOFT AND HARD GLASS FLAMEWORKING: Shade 3.0 lens is suitable for soft glass lampworking and the majority of borosilicate (boro) flameworking. Shade 3.0 lens blocks 100% of UV light and 95% of near-IR infrared light.
- ANSI Z87.1 STANDARD: Be prepared for the unexpected with high-impact lenses and frame - full-coverage frame protects the eyes from impact, foreign objects and radiation sources including lateral protection.
- OPTICAL-GRADE COATINGS: Lenses include ophthalmic-grade anti-scratch coating plus optical-grade backside anti-reflection coating to improve clarity, and super hydrophobic top-coating that resists smudging and makes the lenses easy to clean.
- BALANCED COLOR VISION: Proprietary lens design and blue-flash mirror coating are designed to provide optimally balanced color vision and improved brightness.
