Wearing contact lenses has recently become very fashionable. Still would! With their help, you can not only correct vision, but also change, for example, eye color. Advanced youth acquires lenses for the pleasure of becoming suddenly blue-eyed or black-eyed. But still, first of all, this means of correction is necessary for people with vision problems.
Before purchasing lenses from buyers, as a rule, many questions and doubts arise, which today we will try to consider in detail.
Contact lenses: a review of the shortcomings
One of the common opinions about problems when wearing contact lenses is the fear that they may "roll" over the eyelid and it will be impossible to pull them out. Such fears are not justified in any way: even if you start rubbing the eye “armed” with this optical device, it will only shift, but far beyond the eyelid, and even so that it will be difficult to reach, it will not be able to “hide”. There isn’t much space for that.
But the excitement that the contact lens may fall out and will have to be searched for somewhere on the floor has a reason. True, in this case we are talking about the first generation of this means of correction, rather solid and not very convenient. It really could have left its place as a result of shaking or some kind of awkward movement. Modern soft contact lenses (especially silicone-hydrolene) are characterized by a high degree of flexibility and proximity with the tissues that form the eyeballs. They, as a rule, sit like a glove, and do not fall out.
Contact Lens: A Review of Care
The 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 the particles of water that remain on the surface, substances that cause inflammation, irritation or swelling can get into the eye. In addition, the minerals contained in water, even after a single wash, can settle on the lens and change its optical characteristics.
This vision correction product is stored only in the “native” container! No random containers are suitable for this! In the foreign packaging on the walls contains an unremovable plaque of the substance that filled it earlier. And getting its particles in the eyes can cause very serious consequences.
How to use contact lenses
The opinion that the lenses are suitable for absolutely all types of human activities is incorrect. So, for example, you can swim in them only using sealed glasses or a mask, and visiting them in a bathhouse or sauna is completely contraindicated.
But, contrary to popular belief, you can wear lenses in frosty weather - this does not harm them.
How long can I wear contact lenses: tip
Some people think that nothing bad will happen if you use such a convenient device for longer than the prescribed period. After all, there is savings! But the fact is that the lens is an object that is very tightly attached to the surface of the eye, so any, even imperceptible change in state can be a threat to the shell of such an important organ.
The wearing time of 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 avoids problems arising from the plaque that appears over time.
With the exact selection and observance of the rules when wearing contact lenses, they will not harm your health and, in particular, your eyesight.
