Final Answer:
Eye ointments commonly cause allergic reactions on the skin of the eyelid due to their composition and ingredients, leading to irritation and swelling in sensitive individuals. Therefore the correct option is 2.
Step-by-step explanation:
Eye ointments, due to their composition and ingredients, can commonly cause allergic reactions on the skin of the eyelid. These reactions may include irritation, redness, itching, or swelling. The ointment's components, such as preservatives or active ingredients, can trigger hypersensitivity reactions in some individuals.
Eye ointments often contain compounds like preservatives, antibiotics, or corticosteroids that could lead to allergic responses when they come into contact with the delicate skin around the eyelids. The skin in this area is sensitive, making it more prone to allergic reactions compared to other parts of the body. The formulation of ointments can sometimes include substances that some people might be allergic to, causing skin reactions upon application.
Understanding the constituents of ophthalmic preparations is crucial, especially concerning the potential for allergic reactions. Eye ointments, while effective in treating certain eye conditions, can provoke allergic responses due to their components, highlighting the importance of consulting healthcare professionals if allergic reactions occur during or after their use. Therefore the correct option is 2.
