Title Eye complaints in the office environment: Precorneal tear film integrity influenced by eye blinking efficiency
Bibliographic information Jan. 2005, Vol.62, No.1, p.4-12. Illus. 152 ref.
Abstract Based on a literature review, it is concluded that eye complaints due to precorneal tear film (PTF) alteration may be caused by thermal factors (low relative humidity, high room temperature), demanding task content (attention decreases blinking and widens the exposed ocular surface area) and individual characteristics (blinking anomalies, gland dysfunctions, use of contact lenses). These factors and conditions are able to progressively increase water evaporation and faster thinning of the PTF, which causes dryness and dry spot formation on the cornea, possibly followed by corneal and conjunctiva epithelial alterations and eye complaints. Another possible cause of eye complaints is the presence of certain irritating chemical compounds.
