Using 3D glasses - warning
❐
✎ Do not use the 3D glasses as a replacement for your own corrective glasses,
sunglasses, or protective goggles. Incorrect use of 3D glasses may cause eye
injuries.
✎ Do not store 3D glasses in extreme conditions. Exposure to excessively high
or low temperatures may deform the lenses. Do not use deformed glasses.
✎ Do not apply pressure to 3D glasses or subject them to any impact.
Subjecting 3D glasses to rough handling may damage them.
✎ The lenses on 3D glasses are vulnerable to scratching. Use only a soft and
clean cloth for cleaning. A dirty cloth may scratch the lens surface.
✎ Do not scratch the lens surface of the 3D glasses with sharp objects or clean
with chemicals. If the lens surface is scratched, 3D images may not display
correctly.
