Disposable contacts are a relatively recent development in contact lens technology, Introduced in the late 80’s, they have now become the most common type of contact lens. They are meant to be worn for a specific period of time, then thrown out and replaced with a fresh pair of lenses. Their life can be extended by regular cleaning, but of course this defeats the object of the exercise!

To make matters worse in the choice selection, a few types of disposable contact lenses are available ,disposable, frequent replacement, reusable, daily wear (remove them each night), and extended wear (ie sleep with them in).

So why do we need to throw them out at all?

Substances like protein , calcium, and lipids, found  in tears , can build up on your lenses. These deposits make your contacts less comfortable , and can also make your eyes more infection prone.

There are two main ways to avoid contact lens care, one is to sleep in your lenses, and then replace your lenses periodically.

The other more obvious choice is to wear daily disposables, also called one-day disposables, contacts that you discard every night, and replace with a new pair in the morning .

This is widely seen as the best option, it combines the qualities of convenience and health. Convenient because there is no lens cleaning involved, and it’s healthy because there is minimal daily lens protein buildup, and a reduced risk of eye problems caused by sleeping with them in.
