What is the significance of the EFJAC mnemonic?

The EFJAC mnemonic is significant because it outlines the structure of the lens layers in the eye. Each letter in the mnemonic corresponds to a particular layer or component within the lens, helping students and practitioners easily recall the specific anatomical features and arrangements of the lens. This understanding is crucial for fields like optometry and ophthalmology, where knowledge of the eye's anatomy directly impacts diagnosis and treatment. Recognizing the layers of the lens is foundational when discussing conditions that affect vision and the overall health of the eye, as each layer plays a distinct role in light refraction and clarity of vision.
