  What is a spherical lens? What are aspheric lenses? What's the difference between the two? Why would you recommend aspheric lenses to me? Let's just talk about the difference between the two.
  
  What are spherical lenses?
  
  Imagine a transparent sphere with a circle in front of us. The surface of the sphere is a surface, which is called a sphere. Spherical lens simply means that one of the surfaces of the sphere is chosen as the lens.
  
  Spherical lens
  
  What are aspheric lenses?
  
  Literally, it is easy to understand: what is "non"? "No" means "no", so what is aspheric lens? In fact, it means that the lens is not spherical.
  
  Aspherical lens
  
  In appearance, the spherical lens is a "big belly", but the non-spherical lens is relatively flat, so from the aesthetic point of view, aspheric lens will look better. Because aspheric lenses are precisely designed and the combination of lens degrees is optimized, they are thinner and more collision resistant than spherical lenses. Therefore, people with higher degrees generally wear aspheric lenses.

  And when you look at the world through the lens, the difference is even more obvious.
  
  Through the comparison chart, we can see at a glance that:
  
  When looking around a spherical lens, there will be distortion. Because of the non-spherical surface design, non-spherical lens can minimize the difference between the edges of the lens. It is more natural to see the object, less deformation and more realistic.
  
  Aspheric lenses are so good, why do people choose spherical lenses?
  
  For friends with mild myopia, wearing spherical and non-spherical lenses is almost the same, there will be no aberration problem, lens thickness is similar. Considering the price factor, spherical lenses can be chosen.
  
  In addition, for a very small number of people who are particularly sensitive to color, such as wearing aspheric lenses and feeling rainbow phenomenon, you can try to replace spherical lenses.
