Make sure your safety glasses are protected with a Bollé semirigid polyester case.
 
The small size is suited to wearers of the '+' range of safety glasses which are their smaller fitting ranges. It would also easily fit most pairs of reading glasses as an alternative to standard felt cases. 
 
The case is lined with anti-scratch material and has no shape inside making it more versatile, yet it keeps your glasses held snugly with room for a microfibre cloth. 
 
An excellent case overall.
