Safety over-glasses and fit-over sunglasses are an extremely cost effective way for spectacle wearers to obtain protective eyewear without the need for more expensive specialist prescription glasses. These safety fit-overs from Global Vision are made to high quality specifications in order to meet the requirements of the European CE EN-166-F and American ANSI Z87.1 standards. They must pass six different tests for optical quality plus three different tests for impact resistance including a test that shoots a 1/4 inch steel ball at over 100 mph and leaves no more than a dimple on the lens. All our prices include free UK P&P, international orders are just £3.97 extra.
