Suggestions for writing an assignment:
Read the assignment carefully. Scan through the whole material of the course, answers may be linked
within the blocks units. Draw a rough outline of your answers in your own words. Support your answer
from your clinical experience. Make a logical order. Then write your answer neatly and submit. Give
illustrations and tables wherever necessary. You must retain a Xerox copy of all these assignments. Do
not copy from printed course material. Answer each assignment on separate sheet. On the first page of
the assignment response sheet, write the course code, course title, assignment code, name of programme
study centre (PSC) and the date of submission. Your enrolment number, name and full address should be
mentioned on the first page. The first page of your response sheet should look like the format given.

PART ‘A’
1. A patient has Exophoria @ 6m, and the practitioner wishes to prescribe 1 Prism Base In for each
eye. If the patient’s prescription is RE -4.00DS, LE -4.00 DS, how much decentration (and in
what direction) will be required to supply the prism? Give the details of calculation.
2. On the basis of the relative spectacle magnification formula for axial Ametropia, show that a
minimum of Aniseikonia will occur in Anisometropia due to axial Ametropia when spectacle
lenses rather than contact lenses are worn.

power @ front surface of a lens?
4. Write about the most recommended glass design with visual demand for the individuals like
