did you mean protist?
if you did, then protists means every animal in the eukaryotic branch of the phylogenetic tree (yes, that means you and me) however, protists are usually described and studied in the scientific community as the unicellular eukaryotic organisms.
So, to rephrase, what you are study is probably the unicellular eukaryotic animals that do not include plants, macroscopic animals, and fungi.
Do u mean protists? prosists can be any of various one-celled organisms, classified in the kingdom Protista, that are either free-living or aggregated into simple colonies and that have diverse reproductive and nutritional modes, including the protozoans, eukaryotic algae, and slime molds: some classification schemes also include the fungi and the more primitive bacteria and blue-green algae or may distribute the organisms between the kingdoms Plantae and Animalia according to dominant characteristics.

You should follow up with your ophthalmologist/optometrist to have your intraocular pressure checked regularly. If you notice a burning/stinging sensation in your eyes after you put it in at night this is normal, but if it prosists into continuous redness and irritation this may be a sign of an allergic reaction you have to this particular drop. Lumigan also has the same ingredent as the new eyelash growth drop "Latesse", so you may notice a change in your eyelash length and thickness in a couple weeks/months.
