Glass trifocal lenses provide three distinct vision zones—distance, intermediate, and near—delivered with the exceptional clarity and scratch resistance that only real glass can offer. Designed for wearers who need clear focus at multiple distances, trifocal glass lenses feature two visible lines that separate each segment for precise, easy-to-locate viewing areas. They are ideal for anyone who frequently switches between computer work, reading, and distance tasks and prefers the sharp, long-lasting performance of glass.
