ROR is a unique type of lens cleaner and goes a step beyond routine cleaning. ROR means ""residual oil remover"" and was specifically designed to remove the microscopic film of oil that is caused by environmental pollution. The majority of lens cleaners are simply silicone, alcohol or glycerine based products. Instead of removing the embedded pollution from the pores and surface of a lens, they tended to coat it, thereby defeating the original intention. ROR has redefined the science of lens care by utilizing a formula of natural ingredients that removes the microscopic oil residues from the surface and pores of glass and plastic. When you clean a lens with ROR you will see a noticeable difference in brightness and clarity of your lens. For the first time you will experience pollution free, unimpeded vision. Because ROR removes the microscopic oil residues dust has nothing to adhere to and the surface of the lens remains cleaner for longer.
