Viewfinder eyepiece selection ░42, 43░
The table below provides the choice of correction
eyepieces available in connection with an eyeglass
prescription. Firstly, decide which eye you would nor-
mally use for viewing. Then check your prescription
bearing in mind that in ophthalmic terms O.D stands
for the right eye and O.S stands for the left eye. In the
table, read off the appropriate eyepiece that is along-
side your prescription figures.
If your cylindrical eyeglass prescription is more than
0.5 dioptres, it is recommended that you always wear
your eyeglasses for viewing and focusing.
Please note that the eyepiece, including the correction
glass holder, is constructed from a rubber coated plas-
tic material to minimise the risk of scratching eyeglass
lenses.
