Depending on the type of lens you are wearing, there are many different options for cleaning and disinfecting your lenses. Like all synthetic materials, contact lenses are subject to a buildup of micro-organisms and deposits. If not removed, these deposits and absorbed materials can build up on the lens surface which over time may result in the reduction of comfort and vision as well as an increased risk of contamination.

Among other things, water contains organisms, which can lead to serious infections of the eye through microbial contamination.

As such home made saline, purified water from home tap should not be used to rinse contact lens.
