For those looking for a trendier look, 1.67 high-index lenses may just be the solution. These ultra-thin lenses are even more customized for relatively thin eyewear frames with prescriptions that have an SPH +10.25~+13.00, CYL 0~-2.00
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.
This lens has an anti-electromagnetic radiation surface coating. This invisible barrier filters out 100% electromagnetic radiation waves and does not produce static electricity. This in turn offers even more protection for the eyes.
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.
