Traditional lenses have a bulgy, curved shape. Imagine the spherical surface of a ball. An aspheric lens is designed with less curvature than its traditional counterpart. Think: flatter and thinner. In both farsighted and nearsighted prescriptions, aspheric lenses provide a slimmer profile and minimize eye distortion without compromising optical quality. Let’s take a look at how conventional lenses are designed for far and nearsighted prescriptions:

You’ll find that aspheric lenses can be made out of a variety of materials, including plastic. However, they’re often made from a high-index material. Aspheric lenses tend to have more reflections, so an anti-reflective coating is recommended!

For both types of prescriptions, aspheric lenses reduce the curve of the surface, either by minimizing the thickness of the center or the edges of the lens.

With aspheric lenses, individuals with strong prescriptions do not have to worry about the thickness of the lens in the frame. This opens up their options when it comes to selecting a frame shape and size.

The long answer: Individuals with strong farsighted prescriptions should choose aspheric lenses if they are concerned about the bulging appearance of the lens or the magnification of their eye. But aspheric lenses aren’t just in prescription eyeglasses, they are available in reading glasses, too! Aspheric reading glasses provide all the benefits mentioned above and are a particularly good choice for those with high reading powers (we carry up to +3.75).

What are aspheric lenses and why might you want to use them? Using the same revolutionary technology that has changed the way photographers choose their camera lenses, many reading glasses feature thinner and lighter lenses than ever. They’re called aspheric lenses, and increasingly more eyeglass wearers are making the switch. Let’s dive in to learn more about this lens technology and the benefits of this lens type.

When choosing aspheric lenses, make sure that the center of your eye is lined up with the middle of the lens for clear vision.
