What is a common sign of dry eye in contact lens wearers?

Blurred vision is often a common sign of dry eye in contact lens wearers because when the tear film is unstable or insufficient, it can lead to variations in the refractive quality of the lens as well as the cornea. This instability may cause light to scatter, resulting in a lack of clarity in a person's vision. When the eyes do not maintain an adequate moisture level, the dryness can also cause the contact lenses to not sit properly on the eye, further contributing to blurred or fluctuating vision.

In contrast, increased tearing typically occurs as a response to dry eye, and while this may seem paradoxical, it is the body's way of trying to compensate for the dryness. Redness of the conjunctiva can be an indication of irritation or inflammation but is not exclusively associated with dry eye specifically in contact lens wearers. Eye fatigue is also common among contact lens users but is more often related to prolonged lens wear or strain rather than dryness alone. Understanding the symptoms associated with dry eye can lead to better management of comfort and lens use for individuals affected.
