Blue light blocking glasses are made with  lenses that block or filterout harmful blue rays that emit from computer screens on phones, laptops, computer screens and tablet screens. The lenses keep your eyes protected from glare and potentially reduce eye health problems the retina sustains during prolong exposure to blue light. 

Spheric lenses have a single curve in their design, while aspheric lenses offer varying deflection  This unique design make lenses thinner and create an over all flat surface making them esthetically pleasing because they prevent magnifcation of your eyes. 

This lens comes with an anti-electromagnetic radiation surface coating. This invisible barrier filters out 100% electromagnetic radiation waves and does not produce static electricity.

In addition this lens offers a Hydrophilic Polymer coating  which effectively reduces the buildup of water droplets (condensation) on the lenses caused by sudden high or low temperatures. This in turn offers even more protection for the eyes.
