Duochrome test is to verify spherical endpoint i.e strongest positive or weakest negative lens yielding best visual acuity, so in the actual test do you use BCVA n then test ?

Gud explanation sir tq for the vdeo While doing subjective refraction pt sys -3.00 ,-3.25 6/6 is same so here we are giving -3.00 bcox less minus and more plus Whereas in duochrome. With -3.00,-3.25 R better we are add up with -0.25 :ie: -3.50 pt sys duochrome balanced or G better .in this condition which power we hv to stop -.3.25?? Or(subective . In -3.00 6/6)

Thankyou.. We should perform duo chrome test for sure..after this we need to reduce -0.25 or add -0.25 ..it depends on patient's visual acuity, if patient is sharply 6/6 you can reduce -0.25.. And if patient is monocular partly 6/6 then it's fine no need to reduce . Because binocularly he or she will be perfectly 6/6. Hope this is answer the question.
