Types of contact lenses

The main criterion by which contact lenses are differentiated are the terms of their use. Thus, modern lenses are divided into:

  • Daily: put them on in the morning and discard them in the evening.
  • The lenses for a month: these lenses are stored in a special container with a solution. They are put in the morning and and placed in a solution at night.
  • The lenses at for three months: they have the same method of use as lenses for a month, but their shelf life lasts for three months only.
  • The lenses of  so-called slow action: this type of lenses, according to advertising, can be worn for a week. But ophthalmologists are strongly against such lenses, as they increase the risk of inflammation in the eyes.
  • Lenses for six months: they are almost not used any longer.
