Eyekepper Titanium Rimless Tinted Computer Reading Glasses for Men and Women

The Eyekepper BB60 lenses feature a transparent design with a 12-layer yellowish coating, providing 100% UV protection. Using a spectrometer, the blue light blocking performance has been thoroughly tested: it blocks 35% of light within 500nm, 42% within 490nm, 49% within 480nm, 55% within 470nm, 60% within 460nm, 64% within 450nm, 67% within 440nm, 77% within 430nm, 97% within 420nm, and more than 99% within 400nm-410nm. This results in a 20% color distortion due to the filtering of 30% of blue color.

The product dimensions are as follows: the frame material is Memory Titanium, the lens width is about 1 7/8 inches (47mm), the frame width is about 4 3/4 inches (120mm), the lens height is about 1 5/8 inches (42mm), the bridge (DBL) is about 11/16 inch (18mm), and the temple length is about 5 1/8 inches (130mm), without a spring hinge.

According to the Occupational Safety & Health Administration, the preferred viewing distance for VDTs (Visual Display Terminals) ranges between 18 and 24 inches (45.72 and 60.96 centimeters, respectively). The Eyekepper BB60 lenses are designed to filter out 100% of the most damaging low-level blue light and nearly 60% of high-energy visible light from various electronic devices, such as tablets, phones, TVs, and computers.

The Eyekepper brand offers different blue light blocking strengths, including BB40 (40% blue light blocking), BB60 (60% blue light blocking), BB90 (90% blue light blocking), and BB98 (nearly 100% blue light blocking) for wavelengths from 395nm to 500nm.

To thoroughly test the blue light protection, Eyekepper utilizes a spectrum analyzer to measure different wavelengths (e.g., 400nm, 430nm, 460nm, and 550nm) and a blue light meter to test the 450nm wavelength. Additionally, a UV pen-shaped light and a card are used to test the UV light data for wavelengths less than 400nm.

Before shipment, Eyekepper tests the optical properties of their products, including strength, pupil distance, horizontal position, astigmatism, prism, and blue light spectral distribution, using their proprietary optical performance meter.

It's important to note that blue light, which is located right next to UV light on the spectrum, is comprised of high-energy, low-wavelength light. Electronic devices with backlit screens, such as smartphones, iPods, laptops, and computer monitors, emit large quantities of this blue light, which can disrupt our internal circadian rhythms and affect the body's natural melatonin production, making it harder to fall asleep at night.

To ensure the longevity of the violet block glasses, it's crucial to avoid cleaning them with paper towels, clothing, alcohol, household detergents, or soaps.
