Contact Lenses for Dry Eyes

If this layer dries out, the lens starts feeling like sand. Is this the inevitable price you have to pay for the convenience of contact lenses, or is there a better alternative?

There are several causes for eye dryness. First of all, some people simply produce less tears than others, or their chemical composition of their tears is not adequate. The amount of tears produced usually decreases with age.

Finally, some contact lenses can also contribute to dry eye syndrome. Most soft contact lenses are made from polymers and water - sometimes up to 70% water. While it's this moist, the lens feels comfortable in your eye; but the water evaporates from the lens as the day progresses. So the lens absorbs water from your tears, leaving you with dry-feeling eyes. Generally speaking, the more water the lens contains, the more prone it is to lose its moisture.
