Question

Difference between spherical and cylindrical lens for eye number

Answer 1

Simply put,  cylindrical lenses are made from a flat sheet of polycarbonate, and have a flattened look in the frame. Spherical lenses are a rounded lens for a 3D look . The curved design of spherical lenses (on the Stupefy, Smartefy and Mini models) allows light to travel directly to the eye from any direction; the angles created by a traditional flat lens can cause inconsistent light refraction that strains eyes & skews perception. However Shred’s carved cylindrical lenses (on Amazify and Simplify models) have a slightly tapered form to give you the look you want without compromising your vision.
