Blue Light Filter - Eye Shield is an ideal blue light filter app for mobile devices or tablets created to filter light in order to protect eyes from blue wavelength emitted by screens. It offers good eye care during the night allowing you to look at your phone worrilessly and protects from blue light that can disrupt normal sleep cycles, cause insomnia and hurt your eyes.

What is the explanation behind this issue? 

Blue light is the cause.

It is part of the visible spectrum (ranging from 380 to 550nm) and deeply disturbs the individual circadian rhythm. The blue light does so by inhibiting the secretion of melatonin, a hormone vital in the regulation of sleep-wake cycles. Besides, retinal neurons are being put in danger. Therefore, a reduction of blue light leads irrefutably to an improvement of sleeping quality.

This problem is often being underrated. The negative effects of blue light are:

• Higher risk of macular degeneration, glaucoma and cataract through blue light exposure

• Damaging or killing of light-sensitive cells in the retina

• Risk of permanent loss of vision

• Digital eye strain caused by excessive blue light

• Phase shifting of the circadian clock and suppression of melatonin 

• Higher risk of development of ocular pathologies

• Heightened frequency of blurry vision and risk of turning into a chronic problem 

The effects are cumulative and occur after various years. The Blue Light Filter - Eye Shield app supports you in avoiding those adverse effects.
