The ability of the binocular system to suppress blur from the defocuse
d eye is an important mechanism underlying the success of monovision c
orrection. With a group of 60 new monovision wearers, we found that bl
ur suppression ability varied substantially between subjects and that
crossed dominance influenced blur suppression ability. Symptoms of gho
sting amongst the monovision wearers appeared to be influenced by the
strength of rivalry dominance. An understanding of the suppression pro
cesses underlying monovision may assist in patient selection and manag
ement.
