How to Handle Contact Lens Discomfort? Just what is Contact Lens Discomfort? It might seem like theres no need to formally describe what contact lens discomfort is — after all, the phrase says it all, doesnt it? But a definition is useful, because sometimes people mistakenly think contact lens discomfort is the same thing as contact lens-related dryness or contact lens dry eye, which are related but different. To clarify matters, a nonprofit organization of eye care professionals and eye researchers called the Tear Film and Ocular Surface Society (TFOS) created a formal definition of contact lens discomfort that identifies these characteristics of the condition: Periodic or persistent awareness or discomfort sensations on the eye while wearing contacts. Vision disturbances may or may not be present. The sensations can be traced to reduced compatibility between the contact lens and the eye environment. May lead to decreased wearing time or discontinuation of contact lens wear. Contact lens discomfort occurs only during lens wear and can stem from either contact lens-specific or environmental causes. Lens-specific causes of contact lens discomfort include the wettability of the lens material, the lens design, lens fit, wearing modality (daily wear vs. extended wear) and lens care solutions. Environmental causes include patient factors (age, use of medications), tear film stability and ambient humidity. A key characteristic of contact lens discomfort is that the unwanted sensations or discomfort go away when you remove the lenses. On the other hand, contact lens-related dryness and contact lens dry eye refer to lens awareness or eye discomfort experienced by contact lens wearers with pre-existing dry eye that may or may not be worsened by lens wear.
