The first lenses were made of glass, of course, they were hard, and they were not comfortable to wear. In the 40s plastic lenses appeared, but they were large and often injured eyes. In 1960, a soft polymer material appeared. He made the lenses more comfortable and comfortable, but it was impossible to wear them for a long time: they missed oxygen and caused increased dryness of the eyes.

Modern lenses are made of silicone-hydrogel materials. This invention made the lenses really popular. Oxygen penetrates to the cornea of ​​the eye almost unhindered, respectively, there are no unpleasant sensations.

Pros Lens

  • You can wear them for a long time: up to 12 hours, while you can actively move without removing the lenses. They are available and training in the gym and pool, dancing and jumping. Accidentally falling on the floor, the hydrogel lenses will not break, which cannot be said when glasses are dropped.

  • They do not reduce the radius of action, and the lens correction is 100%, while the glasses are selected one diopter less. Lenses help improve self-esteem for those who are embarrassed to wear glasses.

But, despite all the positive aspects of hydrogel lenses, people with poor eyesight are not in a hurry to move to the polls to use them.


Consequently, they also have disadvantages:

  • in optical stores contact lenses are quite expensive. They require special care, so a solution is required for their disinfection;

  • use one pair of lenses for a long time will not work. They must be updated every 3 months, as a last resort, every six months;

  • to put on and take off lenses requires dexterity and experience, which is not their positive side;

  • you need to get used to the lenses first, so those who want to change glasses for lenses should not be in a hurry;

  • also with careless use of the lens, corneal injury is possible, and this is fraught with eye inflammation;

  • it happens that a lens that accidentally falls out of the eye disappears without a trace;

  • In case of certain visual defects, diseases, allergies, it is not possible to wear lenses.

So, having considered all the pros and cons of lenses and glasses, it is still impossible to make a choice. Since each case involves its own version. But even people who prefer lenses sometimes change them for glasses. And they are right.

It is very convenient to alternate different ways: when there is no time, eyes are inflamed, and wearing lenses is impossible, or you want to give your image a certain style, you can and even need to wear glasses. But if youth, relaxedness, sport, energy are the mood of today, then lenses are what you need.

Therefore, when choosing means of correction, each person should carefully and carefully approach the solution of this issue, and choose for himself what suits him in this situation.
