Which condition is often related to excessive contact lens wear?

Excessive contact lens wear is closely associated with corneal abrasion due to the physical interaction between the lens and the corneal surface. Prolonged wear of contact lenses, particularly if they are not cleaned properly or if the lenses are worn beyond the recommended schedule, can lead to friction and irritation. This can compromise the integrity of the corneal epithelium, potentially resulting in abrasions.

Corneal abrasions can occur when the lenses become unfit for wear, leading to damage on the corneal surface. The risk increases when lenses are worn while sleeping or for extended periods, which can also reduce the oxygen supply to the cornea, further increasing susceptibility to injury.

While other conditions like conjunctivitis, dry eye syndrome, and eye strain can also be related to contact lens wear, they do not specifically arise as a direct result of excessive lens usage in the same immediate mechanical way that corneal abrasions do. Understanding this relationship is crucial when considering the potential complications of improper contact lens care and usage.
