A comparison of the effect of 3M Fresnel prisms and Trusetal prism foils on visual function

Aim:  To determine any differences in visual acuity (VA) and contrast sensitivity (CS) between 3M Fresnel prisms and Trusetal prisms foils. Methods:  Sixteen participants (mean age 20 years) with normal VA and CS participated. The effect of 5 Δ, 10 Δ, 20 Δ and 30 Δ prism strengths on monocular VA an...
