Blocker Bulbs

Lens blockers are used by vision practices to prepare a patient’s prescription before inserting the eyeglass lenses into a frame. The device requires a bulb to examine the lens up close and ensure that they’re being centered accurately. Lite Source Inc. offers replacement blocker bulbs for your machine.
