Blue Cut Lenses

Blue cut lenses feature a special coating that reflects harmful blue light and restricts it from passing through the lenses of your eyeglasses. Blue light is emitted from computer and mobile screens and long term exposure to this type of light increases the chances of retinal damage. Hence, wearing eyeglasses having blue cut lenses while working on digital devices is a must as it may help in reducing the risk of developing eye related problems.

Our Blue Cut Lenses' Advantages

Our blue cut lenses can effectively prevent blue light radiation.And the lenses are of good quality and are not easily broken.
 


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. Let's take a look at how conventional lenses are designed for far and nearsighted prescriptions:
  • Lenses for farsightedness have a convex curve, meaning they are thicker in the center and thinner at the edges. The stronger the prescription, the more the middle of the lens bulges outwards creating what is often referred to as the "coke bottle effect."
  • Lenses for nearsighted prescriptions have a concave curve, meaning they are thinnest at the center of the lens and thickest at the edge.
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.

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)
