Specialty. Neurology, ophthalmology. Diplopia is the simultaneous perception of two images of a single object that may be displaced horizontally or vertically in relation to each other. [1] Also called double vision, it is a loss of visual focus under regular conditions, and is often voluntary.
Refractive correction can be worn under the goggles ; Good starting point when investigating the nature of diplopia i.e. to find manifest, intermittent, crossed or uncrossed diplopia; It is less dissociative than a cover test; Can be used to determine if a patient will demonstrate binocular single vision with corrective prism or head posture

In surveying, tape correction (s) refer (s) to correcting measurements for the effect of slope angle, expansion or contraction due to temperature, and the tape's sag, which varies with the applied tension. Not correcting for these effects gives rise to systematic errors, i.e. effects which act in a predictable manner and therefore can be ...
