When buying contact lenses, water content is one of the parameters that must be considered. According to the specific numerical range, the water content can be divided into three gears: high, medium, and low, so which one should be better?
According to most people's thinking, lenses with high water content are softer and easier to be accepted by the eyes, so they will think that high water content contact lenses are better. But in fact, there is no absolute difference between good and bad for the moisture content of contact lenses. The high water content blindly pursued by the wearer may not be suitable for them, and it is not comfortable to wear.
If your eyes are prone to dryness, you should choose contact lenses with low water content to reduce water evaporation. The outer surface of our eyeballs is covered by a thin lipid layer formed by tears, which maintains the water balance in the eye. After the contact lens is put into the eye, the tear layer is not stable enough and the tear evaporates faster. If a lens with high water content is used, after the water evaporates, the lens will absorb the tear to make up for the missing water, which makes the dryness symptoms worse and worse.
If your eye nothing wrong, then choosing a contact lens with high water content, also pay attention to keeping the eye moist. At the same time, because high-water-containing lenses are easier to absorb and deposit, the formed deposits are more difficult to clean, and it is necessary to clean the lenses to avoid affecting the quality of the lenses. In addition, you can also buy a special eye moisturizer for contact lenses to help maintain moisture in the eye.
Inadequate contact lenses may cause a series of ocular complications, so you must make a reasonable choice based on your own situation. We recommend that you do an eye examination before buying contact lenses and make sure you are suitable for wearing them before fitting them, so as not to cause unnecessary damage to your eyes.
