Lenses in glasses used to be made with glass. However, newer plastic materials are the norm now and have proven to be more impact resistant (glass lenses are a shatter risk!), lightweight (glass lenses are heavy!), and durable.
Eyeglass lenses come in a variety of materials:
-Polycarbonate lenses are necessary for kids or those with only one good eye. These lenses are shatterproof, impact resistance, block UVA & UVB rays, and are also very light!
-Hi-index lenses are needed for stronger prescriptions. This material makes lenses thinner, slimmer, and more lightweight.
-Mid-index are much lighter than glass and are ideal for those with mild to moderate prescriptions. This material is also less expensive than hi-index lenses.
