Now that we’ve a brief overview of polycarbonate lenses why don’t we consider a few of its advantages and disadvantages. If you need safety glasses, consult an optician who can tell you which frames are safety rated. Trivex lenses have an increased Abbe value and may produce sharper peripheral vision with less chromatic aberration than polycarbonate lenses.

Common Lens Materials In Glasses

Especially for strong prescriptions like my daughter’s since it eliminates the “coke bottle” look. I purchased traditional glass lenses in mine 5 years ago and they still don’t possess a scratch. Therefore, in case a person works in an environment requiring safety glasses, polycarb is really the only way to go. It sounds like I need to look out for scratches on my lenses, though.

Although the safety features of polycarbonate for eyeglasses are undisputed the usage of polycarbonate in consumer products has been around question.

Glass lenses are optically clear, clearer than polycarbonate lenses. It is also scratch resistant and does not require any additional scratch-resistant coating.
