What is the process of eyelid eversion primarily used for?

The process of eyelid eversion is primarily utilized to examine the area underneath the eyelid. This procedure allows healthcare professionals to inspect the conjunctival surface, which can reveal conditions such as foreign bodies, infections, or signs of inflammation that may not be visible when the eyelid is in its normal position. By eversion, the inner eyelid is brought into view, enabling a thorough evaluation of any abnormalities or health issues that may be present in that concealed space.

While inspecting the eyeball's surface, evaluating the eyelid's health, and measuring intraocular pressure are important components of an eye examination, they do not capture the primary purpose of eyelid eversion, which is specifically focused on the area beneath the eyelid.
