Wearing contact lenses has recently become quite fashionable. Still would! With their help, you can not only correct vision, but also change, for example, eye color. Advanced youth acquire lenses for the pleasure of suddenly becoming blue-eyed or black-eyed. But still, first of all, this means of correction is necessary for people with vision problems.
Before purchasing lenses, buyers usually have a lot of questions and doubts, which today we will try to consider in detail.
Contact lenses: feedback on the shortcomings
One of the common misconceptions about wearing contact lenses is the fear that they can "roll" behind the eyelid and cannot be pulled out. Such fears are unfounded: even if you start rubbing your eye strongly, “armed” with this optical device, it will only shift, but far beyond the eyelid, and even so that it will be difficult to get it, it will not be able to “hide”. There isn't much room for that.
Herethe excitement that the contact lens might fall out and have to be looked for somewhere on the floor is justified. True, in this case we are talking about the first generation of this correction tool, which is rather hard and not very convenient. It really could leave its place as a result of shaking or some awkward movement. Modern soft contact lenses (especially silicone-hydrolic) are characterized by a high degree of flexibility and proximity to the tissues that form the eyeballs. They usually fit like a glove and don't fall out.
Contact lenses care review
Lenses should never be washed with ordinary water, even very high quality. It is non-sterile and therefore cannot be used for such a procedure. Together with water particles that remain on the surface, substances can enter the eye that cause inflammation, irritation or swelling. In addition, the minerals contained in the water, even after a single wash, can be deposited on the lens and change its optical characteristics.
Keep this vision correction product only in its "native" container! No random containers are suitable for this! In foreign containers on the walls there is a non-removable coating of the substance that filled it earlier. And hitting its particles in the eyes can cause very serious consequences.
How to use contact lenses correctly
The review that lenses are suitable for absolutely all types of human activity is incorrect. So, for example, you can swim in them only usingsealed glasses or a mask, and visiting a bath or sauna in them is completely contraindicated.
But, contrary to popular belief, you can wear lenses in frosty weather - it does not harm them.
How long can you wear contact lenses: review

The period of wearing this optical device is calculated by specialists depending on the characteristics of the source material: its moisture content, shape and gas permeability. And only strict adherence to the terms of use of the lens allows you to avoid problems arising from the plaque that appears on them over time.
With accurate selection and compliance with the rules when wearing contact lenses, they will not harm your he alth and, in particular, your eyesight.
