In the workplace, it is the responsibility of the employer that all employees have a safe work environment. Safety specs are as important to not just employees but also the employers themselves.
Safety spectacles should be durable as well as comfortable. Added features include lightweight, easily cleaned and non restrictive view. Sometimes it is necessary to wear them in conjunction with other safety equipment such as head or respiratory protectors.
Frames for safety specs are usually made out of polyvinyl chloride (PVC) with ventilation holes to prevent fogging.
Lenses are also made out of a tougher plastic such as polycarbonate or Trivex (PNX). These lenses are light weight, tough t distort easily at high temperatures. They are also good at absorbing UV radiation and do not conduct electricity. Lenses can be made to someone s prescription in single vision, bifocal or even varifocal format.
