5-Part Functional Eye
Six times life-size unbreakable vinyl plastic replica of the eye is packed
with useful teaching features. On the exterior of the eyeball is the
cornea, through which the iris and pupil are visible. The large
lacrimal (rear) gland, attachments, for all six muscles that move the
eyeball, the optic nerve, and surrounding blood vessels. The eyeball
divides in half to study the interior. The iris / cornea can
be removed as can the functioning Lucite lens, which magnifies and forms
inverted images. The transparent vitreous body exposes the choroid
coat and retina. Rods, cones and other retinal microstructures are
detailed in a highly magnified diagramatic cross section. 42
hand-coded features are identified in the corresponding key. Mounted
on a hand rubbed hardwood base, the model measure 6 x 6 x 6 inches. 5 Part Functional Eye -
Student Version
This is a simplified version of the above. It is still six times
life-size and packed with useful features, such as the Lucite lens that
magnifies and inverts. Five detachable parts: the upper hemisphere,
the iris/cornea unit, the Lucite Lens, the transparent vitreous body, and
the retina. The eyeball disassembles and reassembles with ease so
students can effectively learn through hands-on activity. A two page
study guide highlights 19 principal features.
Functional eye with Lenses
This easy-to-use anatomical model of the eye is an excellent tool for
studying function. the flexible lens allows you to focus an image on
the retina and the changeable shape allows you to demonstrate
nearsightedness, farsightedness and normal vision. Also demonstrate
the image inversion that occurs in the human eye. The model consists
of: two halves of the sclera (one with retina), lens holder, two convex
lenses, correction lens, (convex and concave). Comes with a
carrying case, candlestick holder, two candles and detailed
instruction manual. 49 x 5.5 x 18 cm
Large Multi-Function Eye
with this model the function of the human eye and the upside down display
of a picture on the retina can be taught very effectively. By moving
the retina, the shape of the eye may be changed. The lens and
ciliary body are made of silicone to allow the change of form and
thickness of the lens. Pictures can be projected on the retina,
which allows you to demonstrate: accommodation of the lens, near point of
vision, myopia (nearsightedness) hypermetropia, presbyopia and how to
correct these problems with glasses. Comes on wooden base with
detailed instruction manual. 45 x 20 cm Budget Multi-Function Eye
Same features as above, but smaller in size. 32 x 18 cm
