Trivex lenses are a newer material than polycarbonate, are more lightweight and have better vision correction in some people. They have natural UV protection but are not as scratch resistant.
High index lenses are for those who need strong prescriptions. They are lighter and thinner than polycarbonate. They work best with an anti-reflective coating.Learn more about Glasses & Contacts
