JIS single-lens overglasses safety glasses without strap SN-770A 1 piece

This is a compact over-glasses type that can be used with glasses. The frame width can be adjusted in three stages, the temple angle in five stages, and the flexible frame provides a soft fit. It has excellent impact resistance, abrasion resistance, and heat resistance. Anti-fog treated lenses ensure a safe and clear view. These over-glasses are designed to be worn over prescription glasses, and can also be worn by people who do not wear glasses. The cushion bar cushions the impact on the face when flying objects collide with the glass and prevents dust from entering through the top of the glass.
