I did an eye test today and want to learn everything about the tests. It's really fascinating!

[@optometry-with-samir]

You did Duochrome test?

[@diogeneslantern18]

@@optometry-with-samir this was one facet of it, yes.

[@R3cce]

Quite interesting. Without my glasses, the red letters are definitely more bold/clearer. This means that i have myopia.

[@optometry-with-samir]

Yeah....
You need to check your vision and Refraction.

[@willa435]

what if the best vision of px is 20/50 can i use this duchrome test

[@optometry-with-samir]

Then Duochrome Test won't be reliable.

Kya duchrome test astigmatism wale patients par bhi karna chahiye ya nahi

[@optometry-with-samir]

▪️For pure astigmatism (without any spherical power), this test is not required.
▪️If any patients is having astigmatism with spherical power then you can do this test. But first you have to correct astigmatism then go it...

[@SmilyMmn]

Sir, can we do both for myopes and hyperopes for this test?
Is this reliable with more than -0.75 or +0.75?

[@optometry-with-samir]

Yeah,
We can do this test both in Myopia and Hyperopia.

[@SmilyMmn]

@@optometry-with-samir what about the 2nd part of the question sir?

[@rajeshtripura725]

[@optmful]

Well explained. but at 2:45 run time, you mistakingly said we add +2.5 instead of saying +0.25. please correct it. This may mislead freshers. Thanks

[@optometry-with-samir]

In the text, it is mentioned 0.25D.
It's not possible to change the voice now. There even an example, hope everyone will understand.

[@kanchanmandal1065]

thank you sir
Sir what about if patient have cylinder power can we do if patient have both power sph and cyl clear me sir.....

[@optometry-with-samir]

If the patient has spherocylinder power then first we have to correct cylinder power then we can do Duochrome Test to identify spherical end point.

[@kanchanmandal1065]

Thank you so much sir for clearing me...

[@elaineleong1407]

why my optometrist didn't give me duochrome test?

[@optometry-with-samir]

It's not mandatory for all. We do this to the patient when we find someones accommodation is fluctuating.
There are several methods for selecting final prescription. Duochrome is one of them. Don't worry
