Hi-index lenses offer people who wear eyeglasses with lens choices that are thin, light and attractive.
For people who have strong prescriptions for nearsightedness, farsightedness or astigmatism, hi-index lenses are a great way to avoid lenses that are thick, heavy and distort the natural appearance of your eyes.
The lenses in a pair of eyeglasses correct vision by bending or refracting light as it passes through each lens. With conventional plastic and glass lenses, the more light that needs bent, the thicker the lenses must be.
Hi-index lenses are different. Here’s how they work and the benefits they offer:
Increased Light Bending Abilities
Hi-index lenses are made of a special material that is able to bend or refract light much more efficiently than conventional lenses. This means less lens material needs to be used to bend the appropriate amount of light that corrects vision.
Due to the increased ability to bend light, hi-index lenses are much thinner than conventional plastic and glass lenses. Therefore, the profiles of eyeglasses are not dominated by thick lenses when hi-index lenses are used.
Because less material is used with hi-index lenses, they do not weigh as much as conventional lenses. This makes them light weight and comfortable to wear.
The fashions of today’s most popular frames have either very thin rims or no rims at all (rimless frames). The thickness of the lens becomes very important with these styles of eyeglass frames. When lenses are too thick, the balance between the frames and lenses becomes disproportionate, resulting in a pair of eyeglasses that are not as cosmetically appealing as they could be with hi-index lenses.
Ask Your Eye Doctor About Hi-Index Lenses
Discuss hi-index lenses with your eye doctor to see if they are an option for you and your vision correction needs. They may provide you with the function, comfort and appearance you desire in a pair of eyeglasses.
