Pink Blue Blockers

Case ID:

This invention uses pink lenses as an efficient way to block blue light while appealing to younger users and those who have a difficult time wearing the more visually cumbersome orange or red lenses. The use of blue light blocking glasses have recently become more popular for the general public because an increasing number of individuals spend a majority of their day looking at screens. The most effective lenses at blocking blue lightred and orange lensesare difficult to wear and are not aesthetically appealing to younger users.

Currently, most blue light blocking technology in glasses is manifest in four different colors: clear (to the extent clear is a color), yellow, orange, and redthe darker the color, the greater the ability of the lenses to block blue light. Orange and red are worn by users to promote healthy sleep habits. This is especially important because blue light suppresses the generation of melatonin. Therefore, the logic goes, the use of strong blue light suppression glasses allows the user two benefits: (1) Continuing use of devices that may be necessary for work or entertainment; and (2) Generating melatonin at normal levels and allowing for normal sleep patterns. Furthermore, blue light puts a great strain on the eyes of those who constantly look at blue light, which is no small percentage of the population.
