Fresnel trial sets are indispensable as a tool for the proper evaluation of ocular motility disturbances.
These acrylic prisms allow for a more accurate 
evaluation of large-angle deviations.
Because a rigid Fresnel prism reduces vision less and 
creates less distortion and aberration than the press-on 
prism of a corresponding power, the practitioner can

The patient who is not able to tolerate a prism from the 
trial set due to its side effects would not be a good 
candidate for a Fresnel press-on prism.
