How To Choose the Right Eyeglass Lenses?
The required lens parameters can only be determined by an ophthalmologist. Today, there are specialists not only in clinics but also in modern opticians. The doctor, after conducting an examination, will find out which refractive index is typical for you. The higher it is, the thinner lenses will suit you. There is a pattern: the thinner the lenses, the less distortion the face undergoes.
There are 2 types of lenses depending on the material from which they are made, these are plastic and glass lenses.
- Glass lenses are harder and heavier, but they are less prone to mechanical damage. True, today plastic lenses have a special coating, which makes them more durable. In any case, the choice of which lenses to prefer is yours. Consider the advantages of each material to make the right choice.

For the manufacture of metal frames, hypoallergenic nickel-free alloys are used. Such frames, like plastic ones, can be of various shades and shapes.
The alloys that are used in the manufacture of metal glasses make them light and soft. They are stronger and thinner than plastic ones. Many consider metal-framed glasses to be more fashionable and stylish.
Recently, eyeglasses have become an integral part of the image of a businessperson, so the frames began to be made from alloys of such precious metals as palladium, osmium, and gold.
