Frames are metal. For lenses, some reader sunglasses use shatterproof polycarbonate for impact resistance; listings otherwise simply note the lens type or protection without further material detail.
Many metal-frame readers advertise UV protection and shatter- or scratch-resistant lenses. Some sunglass readers specifically state 100% UVA/UVB protection and use shatterproof polycarbonate construction.
Listings typically use fit descriptions such as Small, Medium, and One Size Fits Most for metal-frame options.
Care instructions vary but commonly recommend spot-cleaning or wiping the lenses. Sunglass readers often advise using a polishing cloth to remove smudges safely.
Some sunglass readers include comfort features like spring hinges and clear nose pads to provide a more secure, comfortable fit at the temples and nose.
Several metal frames are described as prescription-ready. The listings note options to have lenses fitted in-store or by uploading a prescription online through the eyewear service.
