Felix Gray Roebling Blue Light Blocking Computer Glasses w magnification

Blue light blocking glasses for computer use, rarely used. A dark green in tortoise shell pattern. Case & cleaning cloth included. I just didn’t get in the habit of using them and hope they can find a good home. From Felix gray website: How we filter Blue Light differently We embed our technology into the lenses, so our glasses filter 50% of all Blue Light and almost 90% of the highest range without distorting color. Anti-glare & UV protection We apply premium AR and UV protection for each lens. Virtually clear lens No blue-reflective coating and a tint so subtle that it’s unnoticeable while worn. Magnification- these do have slight magnification This may reduce stress on the eye’s ciliary muscle if you’re fixated on your screen all day. ROEBLING style The measurements for most pairs of glasses are located on the inside of the temple arm. There you’ll find listed in order the lens width, bridge width, and temple arm length (49-18-140 for this pair) measured in millimeters. If you already have a pair of glasses that fit you well, we recommend comparing to those measurements.
