Functional Eye Model, Non-Liquid
Product Code : LSK-BL-10152
Functional Eye Model, Non-Liquid (SKU LSK-BL-10152) is an open-design working model of the eye in which a flexible lens of adjustable focal length plays the part of the crystalline lens and a sliding screen acts as the retina. It can be used to show how the eye focuses, how myopia and hyperopia arise and how corrective lenses fix them. Science Lab Supplies quotes the model, with its corrective lens kit, from Ambala, India.
Specifications
All working features of the functional eye are tabulated below. In short, the crystalline lens is a flexible lens whose focal length changes under mechanical stress, the retina screen slides along the optical axis, a lens holder in front takes corrective lenses, and only a one-time liquid fill is needed at first set-up.

Applications and Experiments for the Functional Eye Model
The model turns accommodation and vision defects into a live demonstration: changing the stress on the flexible lens alters its focal length, moving the retina screen creates short or long sight, and a corrective lens in the holder brings the image back into focus. It fits secondary physics, biology and college optics teaching.
- Class 10 science (The Human Eye and the Colourful World): power of accommodation, myopia, hypermetropia and their correction.
- Showing why a diverging lens such as the Concave Optics Experiment Lens corrects short sight and a converging Convex Lens 50mm corrects long sight.
- Class 11 biology (Neural Control and Coordination): how the ciliary muscles change the shape of the lens.
- College physics and life-science courses: linking lens power to the eye, alongside the six lenses of the Glass Lens Demonstration set.
Standard Scope of Supply
The supply consists of the functional eye model, with its flexible lens, sliding retina screen and front lens holder, plus a kit of corrective lenses for the myopia and hyperopia demonstrations. Optical bench items and anatomical eye models are separate products that can be added to the same quotation.
Packing, MOQ and Lead Time
The functional eye can be quoted as one demonstration unit or as several for physics and biology rooms. Science Lab Supplies writes the packing method, delivery time and price into each quotation for the quantity asked, and extra lenses or eye models can appear on the same quotation.
Science Lab Supplies has an Importer-Exporter Code and is able to ship to buyers in Nepal, Bangladesh, Zambia, Rwanda, South Africa and Qatar. Science Lab Supplies is registered for GST (GSTIN 06ADEPJ0574F2ZU). Teachers and buyers can raise questions on the contact page, shortlist items in the enquiry cart, or consult the lab tender page for public procurement.
Frequently Asked Questions
Does the model really need no liquid?
Focusing works without repeated liquid injection, because the flexible lens is adjusted mechanically. However, a one-time injection of liquid is required when the apparatus is set up for the first time.
How are myopia and hyperopia shown?
The screen representing the retina slides along the optical axis. Moving it changes where the image falls relative to the retina, reproducing short sight or long sight, and a lens from the kit placed in the holder corrects it.
How does it differ from the Human Eye kit Model (Functional)?
Both use a flexible lens to show far and short sight. The Human Eye kit Model needs a power supply and battery and has a removable upper eyeball wall, whereas this open model adjusts its lens mechanically.
Who supplies the Functional Eye Model, Non-Liquid?
This working eye model is provided by Science Lab Supplies, operating from Ambala, India. Its team quotes schools, colleges, distributors and tender contractors and can add physics optics items to the same order.
