Exposure to the blue light emitted from screens--phones, and computers—can cause eye strain, fatigue and dry eyes. Blue-light blocking glasses have filters in their lenses that block or absorb blue light to keep screen time comfortable.

Before the lens undergoes further grinding, the lens must be blocked, or mounted, to begin the process. Blocking involves mounting lenses onto a convex or concave surface (inverse of the tool being used) with pitch or wax. A lens can be blocked individually (Figure 3a), but more often, many lenses with the same radii are mounted on one surface
