How To Choose Lenses For Glasses

Buying new glasses is not only about checking your eyesight and finding the right frame. Lenses are almost the key element in glasses, the choice of which will be discussed in this article.

Why are lenses so crucial? They are responsible for the quality of your eyesight and your comfort, it is through them that you will look at the world every day after buying glasses.

First, let's answer what are the lenses for glasses can be:

  • Polymer lenses are a lightweight and safe solution and will suit most wearers. Modern polymer lenses are in no way inferior in optical properties to glass lenses. This is achieved thanks to special coatings, which we will talk about later.
  • Glass lenses are practically not used today because they are heavier and more traumatic. The only reason why such lenses can still be found is that they tolerate high temperatures well (important for professional chefs and welders), and can also have the highest coefficient of thinning (important for very high diopters, over ± 12 diopters).

What Are Progressive Lenses

The most contemporary method of vision correction. The most advanced optical technologies are reflected in these ways.

In the upper part of the lens, there is a zone for distance vision. In the lower part, there is an area for near vision. The upper and lower zones are connected by a "progression corridor" that provides good vision at medium distances.

With such glasses, you get excellent vision at various distances without having to have multiple pairs of glasses. 

Unlike bifocal glasses, in progressive lenses there is no sharp "jump" of the image when looking from a distant object to a close one, everything happens smoothly. Moreover, thanks to this solution, progressive glasses look aesthetically pleasing.

What Are Transition Lenses

They are photochromic lenses that darken when exposed to UV rays. They are manufactured by using patented technology. When the UV light decreases, the lenses brighten again. By automatically adjusting to light intensity outdoors, Transitions lenses dim light and increase contrast, so the wearer can see more clearly and with less eye strain.


Such lenses increased eye protection from bright light outdoors, indoors, and even inside the vehicle. Contains a specially formulated dye to react to both ultraviolet light and visible light.

What Are Bifocal Glasses

Bifocal lenses were invented by Benjamin Franklin, who once got tired of carrying several pairs of glasses with him. In 1784, he took glasses for distance and near, cut them in half, and inserted them into the frame. Above, he placed the "farsighted" halves, below - the "nearsighted". This is how the first bifocals appeared. One part of them made it possible to see well into the distance, the second made it possible to read and work at close distances.

BCL was created to correct presbyopia. "Presbyopia" is a vision problem that affects all people between the ages of 40 and 45. During this time, your eyes lose the ability to focus clearly on small print at close range, such as when reading newspapers or books.
