Types Of Lenses For Glasses: Picking Wisely

There is a typical misconception among humans that the main thing in glasses is the frame. Of course, a lot depends on it - your satisfaction and image, for illustration. But the quality of your eyesight is determined by spectacle lenses. It depends only on the lenses whether you see this world as beautiful as it is.

The world of optics does not standstill. It is constantly evolving, today the market can offer such comfort and superior products that 20 years ago it was difficult to even imagine. In order not to get confused by the variety of items and know exactly what is needed, you need to be aware of what spectacle lenses exist and how they differ from each other.


Different Types Of Lenses For Glasses: What To Choose

Nowadays assistants for vision are sorted according to:

  • material (mineral/inorganic and polymer/organic);
  • the number of optical zones;
  • the possibility of correcting visual defects (stigmatic, astigmatic);
  • refractive index (standard, thin, super thin, ultra-thin);
  • the shape of refractive surfaces (spherical, aspherical, lenticular);
  • influence on the intensity and properties of the light flux (light, colored, with spectral coatings, photochromic, polarizing).

An ordinary person, not a specialist, to choose glasses for himself, it is enough to know only some of the parameters of this list.

Their design provides for different optical power in various parts of the lens, which allows a person to see comfortably and clearly both at close range, in the distance, and at medium distances. Such lenses open up a completely different quality of life for souls with age-related (after 40 years) changes.
