i'm doing a lab on how protein build up will affect contact lenses, what should i use as the protein material?

Question

What material/What should I do to to the contact lense to produce protein build up on it (please don't answer "put it on the eye for a while.")

Answer 1

Substances like protein, calcium, and lipids — found naturally in your tears — can build up on your lenses. These deposits make your contacts less comfortable than when they were new, and can also make your eyes more prone to infection.

Protein deposits are a common form of soft contact lens deposits. They result from the interaction of your contact lens with proteins found in your natural tears. Two different types of proteins form on your soft contact lens:

Native Protein

A transparent, natural protein that is always present in your tears. It has no significant impact on your vision, your health or your lens comfort, and is easily removed.

Denatured Protein

This opaque deposit binds strongly to the lens surface and leads to decreased lens comfort and cloudy vision.

Answer 2

Use something like bovine serum albumin. Its in most labs, it is generally safe (watch out for BSE), cheap, soluble and given you aren't looking at a specific set of proteins found in the eye about as good a choice as any other.

Answer 3

The expert in this field is Brian Tighe at Aston Biomaterials Research Unit, Birminham uk. I suggest to contact him for advice.
