Designed for high prescriptions, 1.74 index lenses are extremely thin and light, delivering tremendous optical quality due to an aspheric design. It’s one of the thinnest and flattest plastic lenses available, which are astonishing up to 40% thinner than 1.50 index lenses. Strong prescription lens wearers are now free from thick and heavy lenses.
