Product Description

What is an Aspheric Lens?

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.

Benefits of Aspheric Lenses

• Less bulging of the lens, giving you a sleeker profile
• More frame options for individuals with strong eyeglass prescriptions or reading powers
• A more natural appearance of the eye (reduces the eye magnification that occurs with farsightedness and the smaller appearance of the eye that occurs with nearsightedness)
• Lightweight (less material is used to make the lens)
• Better peripheral vision
• Higher image quality (more consistent magnification throughout the lens)
