Seeing and insight with 眼
The kanji 眼 has the concrete meaning of the eye, especially the eyeball or gaze as something fixed directly on what is being seen.
From that physical sense, 眼 extends to sight, a person’s way of seeing, and then further to discernment and insight: not just having eyes, but seeing what matters.
Etymology
This kanji is a phono-semantic compound comprised of 目 (eye) as the semantic component and 艮 (stopping / turning back) as the phonetic component, giving the on-reading ガン. These invoke imagery of an eye fixed on something before it, holding it clearly in view.
Sight and View
肉眼 (Naked eye)
肉眼 means the naked eye, the physical eye unaided by tools such as microscopes, telescopes, or cameras. It contrasts ordinary human sight with enhanced or instrument-assisted observation.
It combines 肉 (flesh) with 眼 (eye) to show the natural human eye of the body.

裸眼 (Unaided vision)
裸眼 means bare eyes or vision without glasses, contact lenses, or other correction. It is commonly used when talking about a person’s natural eyesight as it is, especially in contrast with corrected vision.
It combines 裸 (bare) with 眼 (eye) to show the eye in its uncovered, unaided state.

Vision Tools and Protection
