WebHere is a list of some important differences between high index plastic lenses and high index glass lenses: High index plastic is much lighter than high index glass, even … WebHigh index lenses are made of a material that is capable of bending light to a stronger degree than indexes with a lower rating. Because of this, they require less physical material to produce a prescription. Therefore, high index lenses will typically be much thinner and lighter than standard glass or plastic lenses.
WebAs a person who wears high-index lenses, I can assure you there is definitely a noticeable difference between 1.57 Poly and 1.67 high-index. The amount of light that is allowed to refract through the lens is higher, and there is far less distortion because the edges of your lenses are thinner.
