What is a common reason for contact lens intolerance?

A common reason for contact lens intolerance is dry eye syndrome or allergic reactions. When the eyes do not produce enough tears or when there is an imbalance in the tear film, discomfort and irritation can result, making it difficult for individuals to wear contact lenses comfortably. This condition can lead to feelings of dryness, grittiness, and general discomfort while wearing lenses, causing individuals to seek alternatives to contact lens wear.

Allergic reactions can also contribute to lens intolerance. Allergens such as pollen, dust, or even substances in contact lens solutions can irritate the eyes and exacerbate discomfort. These reactions can cause redness, itching, and increased sensitivity, which are all common symptoms that negatively impact the ability to wear lenses.

Excessive light exposure, incorrect lens diameter, and lack of proper cleaning solutions may cause some discomfort or issues with lens wear, but they are less frequently identified as primary reasons for intolerance compared to dry eye syndrome and allergic reactions. Thus, the presence of these conditions significantly influences an individual’s comfort level in using contact lenses, making them a primary concern for those who experience intolerance.
