The lower conjunctival fornix of 241 contact lens wearers and nonwearers were sampled then cultured to determine the presence or lack of bateria. Several other factors were also investigated: the duration of contact lens wear, the hours/day of wear, the type or types of solutions used, lens hygiene, the age, and the sex of the subjects. A Chi Squared Test was used as the criteria of difference. The incidence of bacteria for contact lens wearers did not differ from nonwearers. Incidence was not influenced by any of the other factors either.
