Abstract
Growing number of contact lens discomfort (CLD) and CL dropout incidence rate afflict the development of CL industry. This article analyzes literatures of past 5 years’ on studies of CLD. It reviews the epidemiology and mechanism of CLD, analyzes different characteristics of CLD resulting from CL material, contact lens care system, and wearers. It sketches the relationship between CLD and ocular surface microenvironment, pointing out that CLD is an incompatible status between CL and the ocular surface microenvironment. Literature analysis also reveals that while high-quality optical effect of rigid lens came at the price of unwelcome initial discomfort, soft lens wearing continuously changes the balance of ocular surface microenvironment, leading to time-dependent discomfort. Different components or formulas of contact lens care systems could be transited by CL into ocular surface and induce CLD. Personal features of wearers such as age, gender, race, and psychological state also could be considered as potential CLD risks.
