They are used for acute/self-limiting conditions but ‘ocular discomfort’ is more suitably used for chronic states, like: dry eye syndrome, blepharitis, meibomian gland dysfunction, allergic conjunctivitis, ocular surface toxicity and irritation, lacrimal drainage problems, and cicatricial and eyelid disorders. Idiopathic photophobia and functional problems like hyperopia, phorias, and the condition ‘Computer Fatigue Syndrome’ also cause ocular discomfort; the term 'Asthenopia' is the related technical word.
