Biofinity - a two-week (according to the regulations of the manufacturer) silicone hydrogel contact lens of the third generation for day and extended-wear.
The advantage of silicone hydrogel contact lens is much greater than that of hydrogel lenses measure oxygen permeability (Dk / t 138). Silicone is embedded in the matrix material of the contact lens and forms a "transparent" for the passage of oxygen bars. The level of oxygen permeability of silicone contact lenses oxygen permeability than water (Dk / t 90). That is, the silicone contact lenses, having greater than that of water (tears) oxygen permeability, does not actually interfere with and contribute to the penetration of oxygen to the cornea. This allows you to negate the problem of hypoxia (oxygen deficiency), which can sometimes occur while wearing hydrogel lenses (in the case of misuse).
The most important difference between the third-generation silicone lenses from previous silicone lenses is their natural wettability and "softness". They are, at first glance, indistinguishable from hydrogels, that is also soft and comfortable. This allows the doctor to offer patients more safely instead of the hydrogel lenses.
Users should also be aware of some specific information about silicone contact lenses:
Better to use daily wear (to shoot at night) and daily cleaning;
If you are using the extended (continuous) mode of wearing, in a week (7 days), according to the directive producer you have to discard the lens and replace it with a new one;
Given that Ukraine has no means of care designed specifically for silicone contact lenses, you must as the best way out to use peroxide to clean;
Incorrectly chosen physician silicone contact lenses can cause damage greater than that incorrectly picked hydrogel lenses.
