Frequently Asked Questions
Are the SecureFit 400 glasses suitable for use over prescription eyewear?
The SecureFit 400 is designed as a standalone safety frame and is not intended to be worn over prescription glasses. Shooters who require vision correction should consult with an optician about having prescription lenses fitted to compatible safety frames, or consider using contact lenses alongside the SecureFit 400 for optimal comfort and protection.
Do these glasses provide UV protection in addition to impact resistance?
Yes. The polycarbonate lenses in the SecureFit 400 inherently block 99.9% of UV-A and UV-B radiation, offering solid protection during outdoor range sessions or work environments with UV exposure — even in the clear lens version.
Will the SecureFit 400 fit comfortably with hearing protection earmuffs?
The 3M Pressure Diffusion Temple Technology is specifically engineered to reduce pressure on the ear canal area, making these glasses more compatible with earmuffs than standard safety eyewear. Slim temple arms minimize interference with ear cup seals, helping maintain both a secure glasses fit and an effective acoustic seal from your hearing protection.
