Since these glasses are clear, how do they keep your eyes safe from UV light?
The 400nm UV protective lens coating is the highest industry standard in clear PPE eyewear lenses. Shield your eyes from not only 90-100% of harmful UVA and UVB radiation rays, but also UV light emitted by artificial light sources. Safeguard this coating by cleaning the lenses with a microfiber cloth, and store in the NoCry protective case (sold separately). Avoid using rough cloths or household glass cleaner.
How to reduce the chances of scratching your prescription glasses?
Ensure no part of your eyewear lenses are in direct contact with the OTG glasses. There should be a gap between the lenses of your own glasses and the lenses of the OTG glasses. If you have thin frames, fully extend the adjustable arms of the over-spec glasses. The tops of the frames of the OTG’s should be directly on top of and over the frames of your glasses - both pairs should feel secure and snug.
Are they comfortable enough to wear all day?
According to hundreds of customer reviews, these safety glasses are so comfortable you'll forget you're even wearing them. The unobstructive lightweight construction and the soft rubber nose piece mean they sit lightly on your face. They won't feel bulky or awkward even after hours and hours of work.
NoCry Over Safety Glasses (OTG) protect both your eyes and eyewear for almost $100 less than prescription safety goggles would. No need to have expensive lenses put into your safety glasses or work without clear sight. ANSI Z87, CSA Z94.3 and OSHA approved and certified (certifications embossed on the sides).
The strong and durable polycarbonate wraparound construction offers a high level of direct eye protection, whilst the side covers protect peripherals. Clear UV 400nm scratch-resistant lenses block 90-100% of harmful UV radiation allowing for outdoor use. No optical distortion.
Comfortably and easily fit over most reading glasses (up to 5.7in wide, up to 1.37in high on the sides and 1.77in high in the center). Soft tips eliminate pressure behind the ears and the extendable arms adjust for small and larger head sizes - fitting men, women and youth. Can also be worn as normal large sized safety glasses.
Designed for woodworking, construction, chemistry or science lab and dental work, or shooting (always double-check the safety requirements of your local shooting range) - anything you’d need PPE eyewear for.
To avoid scratches, make certain that no part of your own prescription lenses are in direct contact with the protective lenses of the OTG safety glasses. When wearing the over specs, always leave a sufficient gap between both pairs of glasses.
