Eyekepper Quality Spring Hinges Half-Rim Reading Glasses

EYEKEPPER, a brand of professional and affordable blue light blocking glasses, aims to help reduce eye strain from digital screen use. The frame material is metal, with a lens width of approximately 2 1/16 inches (53mm), frame width of approximately 5 7/16 inches (138mm), lens height of approximately 1 1/4 inches (31mm), frame height of approximately 1 5/16 inches (33mm), bridge (DBL) of approximately 11/16 inches (17mm), and temple length of approximately 5 1/2 inches (140mm), featuring spring hinges.

The Eyekepper BB40 lenses are transparent with a coating that provides 100% UV protection. These lenses do not block the blue color spectrum, which is important for color filtering properties. For those who need to block more blue light, Eyekepper offers the BB60, BB90, and BB98 lens options.

Eyekepper's blue light blocking performance has been tested using a spectrometer. The results show that the lenses block 29% of blue light within the 500nm wavelength, 32% within 490nm, 33% within 480nm, 35% within 470nm, 36% within 460nm, 37% within 450nm, 39% within 440nm, 51% within 430nm, 93% within 420nm, and more than 99% within the 400nm-410nm range. The lenses demonstrate almost no color distortion.

According to the Occupational Safety & Health Administration, the preferred viewing distance for digital screens ranges between 18 and 24 inches (45.72 and 60.96 centimeters, respectively). Eyekepper's blue light blocking glasses effectively filter 100% of the most damaging low-level blue light and nearly 90% of high-energy visible light from tablets, phones, TVs, computers, and other digital devices.

The Eyekepper advantage lies in the professional-grade blue light blocking capabilities of their lenses. The American HEV-Adsorb substrate absorption technology is used in the lens design, allowing for superior absorption of high-energy blue light. Additionally, the anti-blu-ray lenses utilize special U.S. substrate processing technology to protect the eyes from ultraviolet radiation and block UV420, not just UV400.

Eyekepper's BB40 lenses provide 40% blue light blocking for wavelengths between 395nm and 500nm, with the test wavelength at 450nm. The data shows the visible light, remaining blue light, and remaining UV light, demonstrating Eyekepper's commitment to providing comprehensive eye protection.

The premium features of Eyekepper lenses, including the amber tint and 12-layer coating, make screen time more comfortable and help eliminate symptoms of digital eye strain. The lenses are also suitable for outdoor reading, as the tinted lenses provide protection from the sun's UV rays.

Whether you're looking for reading glasses for the office or home, Eyekepper's blue light blocking glasses offer the premium protection you need to maintain healthy eyes in the digital age.
