Eyekepper Computer Reading Glasses - Small Round Blocking Readers +1.75

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 BB40 violet block glasses offer a range of features and benefits to address the issues associated with exposure to electronic device screens.

Filters 100% of the most damaging low-level blue and nearly 40% high energy visible light from tablets, phones, TV, computers, and more. This patented, multi-layer coating is designed specifically to reduce glare, reflect blue light away from the user, and relieve long-term eye strain caused by excessive electronic device use. Whether you're looking for computer glasses for the office or to enjoy a late-night Netflix binge, Eyekepper glasses will provide the premium protection you need.

The blue light emitted from electronic devices can disrupt our internal clock, making us feel like it's midday when it's actually close to nighttime. This can prevent our body from naturally producing the melanin that helps us fall asleep at night. The Eyekepper BB40 lenses are designed to address this issue, providing maximum protection against the harmful effects of blue light.

The package includes a hard zip EVA case and a cleaning soft cloth. To maintain the integrity of the lenses, it's important to avoid cleaning them with paper towels, clothing, or alcohol, and to steer clear of using household detergents or soaps, as these can slowly disintegrate the lens coatings.

The Eyekepper BB40 lenses are made of plastic and have the following dimensions: Lens width of about 1 1/2 inches (38mm), Frame width of about 4 15/16 inches (125mm), Lens height of about 1 1/8 inches (29mm), Frame height of about 1 5/16 inches (33mm), Bridge (DBL) of about 15/16 inches (24mm), and Temple length of about 5 5/16 inches (135mm), with spring hinges.

The lenses offer 100% UV protection and are transparent, with no color distortion. However, if you need to block more blue light and have a more pronounced blue color filtering effect, you may want to consider the Eyekepper BB60, BB90, or BB98 lenses, which offer increased blue light blocking capabilities.

The blue light blocking performance of the Eyekepper BB40 lenses, as tested via a spectrometer, is as follows: block 29% within 500nm, block 32% within 490nm, block 33% within 480nm, block 35% within 470nm, block 36% within 460nm, block 37% within 450nm, block 39% within 440nm, block 51% within 430nm, block 93% within 420nm, and block more than 99% within 400nm-410nm.
