Pupillary Distance (PD) is the distance between the centers of your pupils in millimeters. Most optometry prescriptions include this number (e.g. 62mm). You can also measure it with a millimeter ruler in a mirror or enter standard adult values (62-64mm).

Single Vision lenses have a single continuous focal power across the entire lens, perfect for distance correction or reading only. Progressive lenses feature no-line multifocal vision, allowing clear vision for distance, intermediate screen work, and close-up reading in one pair.

Every Zeelool frame and prescription pair comes with our 365-Day Quality Guarantee. If you notice any manufacturer defects, lens peeling, or hinge issues within 365 days of receipt, our optical support team will replace your pair free of charge.
