1:6.6x life-size eye model for hands-on study. This 4D, three-chamber model reveals internal eye structures with detachable components for detailed exploration. - 1:6.6x enlargement shows the outer, middle, and inner eye walls, plus refractive layers, lens, and vitreous. Parts separate into three sections for focused study. - All major parts are removable: cornea, iris, lens, and vitreous body detach to demonstrate function and spatial relationships. - 4D learning design helps visualize how components fit and interact during vision, improving conceptual understanding. - Durable construction suitable for daily classroom use and repeated handling. - Clear educational value: enhances comprehension of eye anatomy, supports hands-on lessons, and serves as a strong centerpiece for science fairs. Use scenarios - Classroom demonstrations in biology or anatomy to teach eye structure and how vision works. - Science fair projects showing how each component contributes to sight and how changes affect function. - Patient education or self-study in clinics or learning labs to explain eye parts and their roles without a patient explanations guide.
