Which condition is NOT directly related to vision impairment?

Amblyopia
Aphakia
Blepharitis
Esotropia

The correct answer is: Blepharitis

Blepharitis refers to inflammation of the eyelids, which can lead to discomfort and can affect the overall health of the eyes. While it can cause symptoms like redness and irritation, it does not directly cause vision impairment. Other conditions, such as amblyopia, aphakia, and esotropia, are directly associated with vision issues. Amblyopia is a condition where vision does not develop properly in one eye, aphakia refers to the absence of the lens of the eye often leading to significant vision loss, and esotropia involves a misalignment of the eyes that can result in double vision or reduced visual clarity. Therefore, blepharitis is the correct choice as it is primarily an eyelid condition rather than a direct cause of vision impairment.
