Six subjects were fitted with soft contact lenses with 1.5 mm pupil openings. Spatial contrast threshold function CTF were measures on these subjects and comparisons were made between the CTF when wearing the 1.5 mm contact lens and normal contact lens. The spatial CTFs were determined for 8 spatial frequencies between 0.75 and 21 cycles per degree of visual angle using the forced choice staircase procedure. The purpose of this experiment was to determine if changes in CTF from drug induced miosis was comparable to miosis produced by artificial pupil in contact lens.
