In this study, which investigates the relationship between the levels of stereopsis with eye and hand dominance or interpupillary distance, 120 healthy young volunteers were investigated. Eye dominance was determined by modified Miles technique following a complete eye examination. Handedness was assessed with the Edinburgh handedness inventory. Interpupillary distance was measuredwithmillimetric ruler. Stereoacuity wasmeasured in both contour (Titmus test) and randomdot (TNO test) stereograms. The stereopsis scores were evaluated in terms of hand or eye dominance.The correlation between stereopsis score and interpupillary distance was assessed. Main outcomemeasures were stereopsis scores according to hand and eye dominance. As a result, right- and left-handed individuals showed no differences in terms of stereopsis. No differences were found in stereopsis scores between right-and left-eye dominant people. There was a correlation between interpupillary distance and the depth of stereopsis
