Contact lenses may be a boon to mankind but you might realize after continuous use that maybe they could be made better and that their features and method of use can be enhanced. There are various disadvantages to such lenses too.

The cleaning solutions that are used with the lens are very expensive and are not always affordable to all on a long term basis. These solutions have to be bought at regular intervals as they keep the contacts clean and devoid of dirt or bacteria. These solutions if not used could lead to infection and make the eye excessively scratchy and stingy. But even then, if you use contacts your eyes are always prone to infection if one is not careful.
