AR-coated high-index lenses transmit up to 99.5 percent of light to the eye for optimum vision. Translation: high-index is the smart option for stronger prescriptions. Polycarbonate may not be the wrong choice, but your lenses will be thicker. Lens materials affect thickness and weight. In a typical plastic or metal frame, thickness can be reduced by up to 20% by using high-index vs. polycarbonate lenses. High Index vs. Polycarbonate Lenses. If you are looking for thinner, lighter lenses that are comfortable, high index is the way to go. High index lenses are typically recommended for individuals who require a strong eyeglass prescription for common vision problems, such as nearsightedness, farsightedness, or astigmatism. In the past

Although high-index lenses are more expensive than plastic lenses, they can reduce the thickness and weight of an Refractive index refers to the rate at which light bends as it passes through the plastic of the lens. The higher the refractive index, the thinner the glass. High-index plastic lenses have a refractive index between 1.6 and 1.74; the index of ordinary plastic and polycarbonate lenses is 1.5 and 1.59, respectively. Regular Lenses vs. High-Index Lenses . Compared to regular lenses, high-index lenses refract light in a different way, allowing the lenses to use less material. Units called diopters are used to measure the lens power necessary to correct refractive errors.
