    How to study the wettability of the contact lens?

    Contact lens should support a continuous tear film for optimum visual clarity. It should also resist the sorption of tear components as deposition can lead to decreased visual clarity and discomfort. Wettability of the surface affects both the tear film as well as biocompatibility of the lens.

    What is wettability?

    Wettability is the preference of a liquid to be in contact with a solid surrounded by another fluid (liquid or gas). Depending on the application, wettability can be wanted or not.

    Why is contact angle important?

    In industry, wettability is important for example when manufacturing electronics or when planning how to extract oil from the oil reservoir. In all these applications, knowing the contact angle value gives a strong indication on the performance of the product or a successfulness of the process.
