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)
What is UV 400?
Simply put, UV 400 means that the lenses will block Ultraviolet (UV) waves shorter than or equal to 400 nano-meters (nm). All UV waves come in different lengths as shown in the chart below.
UVA: 320-400 (nm)
UVB: 290-320 (nm)
UVC: 200-290 (nm)
Since all of these UV rays are shorter than or equal to 400 nm, they are blocked by the lenses - keeping your eyes safely protected.
This also explains why you can still see color. The color red has a wavelength of 680 nm. Since it is greater than 400 nm, it is not blocked by the UV 400 lenses.
