This set includes 266 trial lenses of varying strengths and types, along with a pair of trial frames, to meet diverse vision testing needs.
The lenses are housed in a dust-resistant aluminum alloy enclosure with a locking design to better protect the clarity and lifespan of the lenses.
The lenses feature a non-magnetic metal edge, making them suitable for use in magnetic field-sensitive environments (such as MRI areas) or other specialized applications.
