Frequently Asked Questions

Q: Are OTG glasses heavier than regular safety glasses?

A: OTG glasses may be slightly heavier due to the larger frame, but are designed for balance. Proper size adjustment of temples generally prevents significant pressure.

Q: What does UV400 mean?

A: UV400 means the lens blocks ultraviolet wavelengths below 400 nanometers, covering both UVA and UVB, providing excellent UV protection for extended outdoor work.

Q: How long does the anti-fog effect last on YF0106?

A: Anti-fog coating life depends on usage and cleaning. Avoid rubbing the inner lens surface and use water or dedicated lens cleaners to extend performance. Replace when fog resistance significantly decreases.

Q: Can prescription lenses be fitted directly?

A: This is a protective spectacle with non-replaceable lenses. It is designed to be worn over prescription glasses. For prescription safety glasses, choose dedicated models with corrective lenses.
