Both soft and hard contact lenses are designed carefully so that they can sit on the eyeball without feeling bulky and uncomfortable. Soft lenses are made of plastics or silicones known as "hydrogels," and they need to remain moist at all times in order to keep their shape.
Hard lenses are a little less reliant on moisture, but they also can start to become uncomfortable if they dry out. Unfortunately, individuals with dry eyes often find that their eyes aren't able to naturally create enough moisture on a regular basis to keep contacts adequately hydrated.
As lenses get too dry, they can cause irritation and blurry vision, which is why many people turn to rewetting drops to restore the necessary moisture.
Choosing and Using Rewetting Drops for Your Lenses
Different types of rewetting drops are designed for different types of contact lenses. You should always make sure that you choose a product formulated for either soft or hard contacts and never substitute one for the other.
Among rewetting drops, most products use a saline solution as their base but these products usually also contain other ingredients that may help extend lubrication and reduce friction between the contact lens and the eye.
Some rewetting solutions also feature ingredients that can remove proteins from the lenses. Rewetting solutions are made to be sterile, which is why you should never substitute water or saliva for one of these products (doing so can increase your risk of developing serious eye infections). On the other hand, rewetting solutions are not designed to disinfect contact lenses, so they shouldn't be used in the place of a multipurpose solution for cleaning or storage.
