Eyekepper Frameless Blue Light Blocking Glasses for Sleeping - Round Rimless Computer Glasses for Men and Women

The Eyekepper BB98 lenses feature a 12-layer coating and offer 100% UV protection. These orange-tinted lenses have undergone testing using a spectrometer to evaluate their blue light blocking performance. The results show that they block 89% of blue light within the 500nm range, 91% within the 490nm range, 93% within the 480nm range, 94% within the 470nm range, 96% within the 460nm range, 98% within the 450nm range, and more than 99% within the 400nm-440nm range.

Due to the significant filtering of 90% of the blue color, users may experience serious color distortion. If this is a concern, Eyekepper recommends considering their BB40, BB60, or BB90 lenses, which may offer a more balanced color experience.

The lenses are designed to block 90% of the blue color, as determined by an online test for color filtering properties.

The product dimensions are as follows: lens width of about 2 inches (51mm), frame width of about 5 1/4 inches (133mm), lens height of about 1 13/16 inches (46mm), bridge (DBL) of about 11/16 inch (18mm), and temple length of about 5 1/8 inches (130mm). These lenses do not feature spring hinges.
