In this experiment, the students should review their knowledge
of the light path in the human eye and the accommodation of the eye
to near and far objects. From the observation of the inadequate
accommodation for divergent incident light using the model eye and
therefore the necessity of its correction with the help of a convex
lens, they should reach conclusion concerning the appearance of
old-age accommodation problems. The experiment gives an
understanding of why older people very often require glasses for
close reading. This allows a differentiation between this type of
defects and the short- and long-sightedness due to inherently
flawed eye structure.
The experiment is demanding in terms of the abilities and skills
required of the students, particularly in the necessity to
extrapolate from the planar model to the real eye.
- Multifunctional light box - All-in-one: Can be used for geometric optics on the table, colour mixing and on an optical bench
- Extension with others sets at anytime, no additional light sources needed, recognition value for students
What is loss of accommodation in old age? Investigate with the
model eye how the problems of accommodation associated with old age
can be corrected.
