Laviana, Joseph E. and Rohles, Frederick H. (1988): Air Travel and Contact Lenses: A Laboratory Study. In: Proceedings of the Human Factors Society 32nd Annual Meeting 1988. pp. 450-454.

“The cabin of an inflight aircraft contains approximately 10% relative humidity (rh). To investigate the impact of this environment on eye comfort, an inflight humidity profile was simulated in a controlled laboratory setting. The experiment was replicated 3 times using a group of 4 subjects (2 males; 2 females) per test. Participants served in both control and experimental roles by wearing a hydrophilic contact lens on one eye and no lens on the other. Subjects provided evaluations of "eye comfort" for both eyes (contact and naked) at specified intervals during the 10-hour test. The results indicated that at 10% rh, there was no significant difference in eye comfort for either wearers or non-wearers of soft contact lenses. However, comfort decreased with the length of exposure (flight time), and for duration of six hours or longer a significant annoyance was reported.”

Laviana, Joseph E., Rohles, Frederick H. and Hoffberg, Linda I. (1987): Dry Environments: The Influence of Low Humidity on Comfort and Health. In: Proceedings of the Human Factors Society 31st Annual Meeting 1987. pp. 1101-1104.

“Individuals are routinely subjected to dry environments. These conditions may result from geographic areas, the heating of indoor spaces, or specialized settings (e.g. commercial aircraft cabins). This paper examines the affect of low humidity from two perspectives: comfort and health. Results indicate that the dry-bulb temperature is only 7.8 times more important than relative humidity (rh) in determining the subjective thermal response, and that rh has a greater role in determining how men feel than how women feel. Additionally, it was shown that a perceivable level of annoyance is experienced by both wearers and nonwearers of soft contact lenses at or below 30% rh, and this effect becomes most pronounced after four hours. Other findings indicated that the perception of varying odor intensity levels (e.g., cigarette smoke) is higher in dry environments; several studies are also reported showing the health related benefits of humidification.”
