The Eyezen lens is a type of blue light lenses designed for everyday use, for people who spend long hours in front of blue light-emitting devices. Essilor Eyezen glasses provide a slight degree of magnification to make sure that wearers keep a healthy distance from the screens while filtering at least 20% of the blue light that is emitted to reduce eye strain. The Eyezen lenses’ prices can range from $100 to $150 depending on the retailer.
