The contribution of technology in the creation of lenses for your lenses.
Currently, what satisfies human beings when choosing glasses are the various models that have been created to keep your eyes comfortable, although what determines the degree of satisfaction entirely will be the types of glasses you choose.
The purchase of this product is not difficult at all, although today it has become a bit strict since the technological advance and variety in both designs and crystals has made people a little more interested when making a choice to have complete satisfaction.
Eyeglass lens materials made by modern technology
- glass crystals: At the beginning of the creation of this product, the crystals were created from bottle glass, they were also made manually and their execution took a certain time, although there was no advanced element to make the task easier.
Nowadays these crystals are created from the same glass but with technological advancement and modification, the work is not done manually, the machines that were modified do all the work and even so, they do the job clean and satisfactory to obtain positive results from an user.
Even with these advances and modifications, glass crystals are no longer commonly used.
The first lenses were created from an extremely fine plastic, they were practically created with what is now known as resin.
The advance of these lenses was not very popular, due to their material they did not have any problem because there were even people who adapted better to plastic lenses than to glass ones, but the disadvantage that there was in this advance was the loss economical since due to the low cost of the resin, users would not pay more than fair.
The crystals made from this material have been extremely satisfactory, from the 1980s until today their use is still discussed.
However, those that exist today are not of the same quality nor are they even made of only polycarbonate, technological innovation has introduced new materials for the creation of these crystals since, in addition to being used for children's lenses, they are more used for bulletproof helmets due to impact resistance, although it does not change much because it is an extremely similar essence to pure polycarbonate.
High index plastic crystals.
Since they were created they have been the best crystals that the market has brought out, from their times to the present they have improved the shape and sizes but their quality remains completely exceptional.
But even so, despite being the latest innovation on the market, it also has its disadvantages and that is that they have caused people to have different reactions since the high level of the materials used do not adapt to any type of pH, that is why This is why it is recommended that they be used under medical observation.
It is a relative measure of how efficiently the material refracts light, which depends on how fast the light travels through the material.
refractive index of a material for crystals is the index of the speed of light in a vacuum, divided by the speed of light through the material of the crystal, which means that they are specially created to protect the eyes from some unsuitable environment and still generate the capacity that the user needs to fully depend on them.
The refractive index of current lens lens materials encompasses a specific variety of high-index plastic, indicating that it will be thinner than glass made with a lower index value.
