One of the most common problems suffered by people who wear contact lenses is that they dry out very easily. Biofinity contact lenses are produced by CooperVision specifically to combat this problem. The objective is that the materials used in production will allow oxygen to pass through the lens and they are also designed to maintain a high water content.
The increased amount of water that is held in the Biofinity contact lenses is made possible by silicone hydrogel. The effect is that these contact lenses will be comfortable for use all day, and people will not have to use rewetting drops as often throughout the day in order to keep their eyes feeling comfortable. There are a number of different lenses on the market that are designed to allow oxygen to pass through the lens. The Biofinity lenses are a little different in that they include hydrogen that bonds with the water molecules and that is what helps them retain moisture better.
On top of the fact that Biofinity contact lenses will keep the eyes moist and let plenty of oxygen be introduced to the eye, they have other advantages. The material that is used remains soft and when they are worn many people will find that they aren’t even aware that they are wearing contact lenses. The edges of the lenses are made rounded for extra comfort and make it less likely to scratch the eye when they are being inserted.
If you want to have contact lenses that offer more comfort, then having ones that introduce more oxygen to the eye and keep the eye moist are going to be preferable to most. The fact that more oxygen is getting to the eye will also keep eyes looking healthier and they will appear much whiter. CooperVision has definitely provided a product that works well and feels great.
