Description

What is blue light?


   Sunlight contains red, orange, yellow, green and blue light rays and many shades of each of these colors, depending on the energy and wavelength of the individual rays (also called electromagnetic radiation). Combined, this spectrum of colored light rays creates what we call "white light" or sunlight.
   Generally, scientists say the visible light spectrum comprises electromagnetic radiation with wavelengths ranging from 380 nanometers (nm) on the blue end of the spectrum to about 700 nm on the red end. (By the way, a nanometer is one billionth of a meter - that's 0.000000001 meter!)

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?

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

1.  Less bulging of the lens, giving you a sleeker profile
2.  More frame options for individuals with strong eyeglass      prescriptions or reading powers
3.  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)
4.  Lightweight (less material is used to make the lens)
5.  Better peripheral vision
6.  Higher image quality (more consistent magnification throughout the lens)
