When are bandage lenses typically indicated?

Bandage lenses are specifically indicated in cases of entropion, where the eyelid turns inward, potentially causing irritation and damage to the cornea due to friction. The bandage lens acts as a protective barrier, helping to shield the cornea from further injury or irritation, while also providing comfort to the patient. By creating a smooth surface over the eyelid and allowing for more natural tear film distribution, these lenses can significantly alleviate symptoms associated with the condition, allowing for improved healing and comfort.

In contrast, options that suggest using bandage lenses for correcting refractive errors or during routine eye exams do not align with the primary function of bandage lenses, which is to protect and promote healing rather than to enhance vision. Similarly, while bandage lenses can sometimes be used in conjunction with treatment for various conditions, their primary role is not treating conjunctivitis directly, as other therapeutic modalities are typically employed for that purpose.
