The lenses of these sunglasses made by Spekkles are coated with an innovative material onto which is printed the club colours. Passers by are exposed to the full impact of the graphics and message. To the user however, the area covered by the perforated film just appears slightly tinted and offers no substantial obstruction to visibility. Spekkles are produced in the UK, and the lenses and frames conform to the European standard BSEN 1836:1997.
