Short Story about Contact Lens

Contact lenses have largely replaced spectacles because of the many advantages they offer. One can avoid the inconvenience caused by the spectacles by using these contact lenses. They just have to be placed inside the eyes and one can move ahead with their daily work. The traditional spectacles are heavy to carry and also one needs to be cautious while wearing the spectacles. Over a period of time, because of the advent of technology, there are many improvements which have been made in the manufacturing of contact lenses.


In earlier days, when the first contact lenses came out people used to find it difficult to carry them. But, the ones that are now-a-days found in the market are very comfortable to use. There are basically two types of contact lenses that are available in the market, they are soft lens and permeable lens which is rigid. The choice of these lenses completely depends on the individual's tastes and priorities.

Permeable Lens
Permeable lens is also commonly called as hard lens and the option varies between the two depends upon the need of the person and the type of the vision problem they are encountering. 

Soft Contact Lens
Plastic polymer is one of the key substances used in the manufacture of soft contact lens. It allows oxygen to flow through it and you will be feeling very comfortable with this lens in your eyes. There are some disposable lenses which can be used for one day and disposed off. Most people select these types of lenses as they do not have to clean it every day. These lenses do not make you feel uncomfortable and the chance of debris getting collected into your eyes is also very low. 


It is hence always advisable that one chooses the lens that would exactly suit them. Once the type of lens that would exactly suit you is determined, there are lots of websites over the internet where you can place and order and get them delivered very easily at your door step. So, if you are thinking about buying contact lens, do not forget to consult an ophthalmologist and then buy the lens.
