High Index Plastic Lenses

If your prescription requires correction for high amounts of nearsightedness or farsightedness, standard glass or platic lenses often need to be quite thick and heavy – often referred to as “coke bottle” lenses.. 

Fortunately, there are high index plastic lenses that are lighter and thinner than standard lenses.  You can have more natural looking glasses.

Chemists have created a variety of new “high-index” plastic lens materials that bend light more efficiently.  This means less material can be used in high-index lenses to correct the same amount of refractive error, which makes high-index plastic lenses both thinner and lighter than conventional glass or plastic lenses.
