Which of the following is a common complication in contact lens wearers leading to discomfort?

Dry eye syndrome is the correct answer as it is a prevalent issue faced by contact lens wearers and can lead to significant discomfort. Contact lenses can alter the natural tear film and disrupt the eye’s moisture balance, resulting in symptoms of dryness, irritation, burning, or a gritty sensation. This sensation can be exacerbated by environmental factors, such as air conditioning, pollen, or prolonged screen time, which can further diminish tear production and lead to discomfort.

The other choices, while they can be associated with various visual or sensory issues, are not as directly linked to contact lens wear. Color distortion can occur in some specific scenarios but is less common and usually related to specific lens types or conditions. Glare sensitivity is often experienced in varying lighting conditions but is not a primary complication of wearing contact lenses. Light sensitivity, or photophobia, may arise from many causes including inflammation or underlying conditions but is not specifically associated with contact lens discomfort like dry eye syndrome is.
