Pages 7 (1757 words)
The conjunctiva is the thin membrane covering the white part of the eyeball (the sclera) and the inside of the eyelids, and it is this membrane that scientists are currently studying to further understand the effects of contact lens use on the eyes. In particular, researchers are conducting studies to reveal the specific effects of contact lens use on the density of the cells that make up the conjunctiva…

Extract of sample

Impression cytology has allowed researchers to look more closely at the cells within the conjunctiva and to study the differences between those tissues that were not exposed to contact lenses and those that were. Various studies have been carried out on various specifications, however it is the cell density that interests many scientists and medical professionals. Cell density, and in particular the density of what are called Goblet cells, are of importance to contact lens studies in relation to the conjunctiva.
Cytology of the conjunctiva is best served by the in vivo method which deals with light reflection differently than other methods of study and actually allows the researcher to gain a better view of the tissue in question. Through this methodology, it is possible to have a closer view of the effects that contact lens use is or is not having on the various tissues of the conjunctiva. ...
