Why not subtract working Distance power in this video? Or performed with WDP?

@optometry-with-samir 5 месяцев назад

If u take +1.50 as a spherical value Than the ans is +1.50/+3.50@180 right?

@optometry-with-samir 11 месяцев назад

Yes... you are right. Stay with us and share with you friends

@santhieswari8537 9 месяцев назад

Sir we can choose the 4th one also am i right

@optometry-with-samir 9 месяцев назад

Q-1: Answer is option A. +5.0 /-3.50 X 90. If we transpose it it will be +1.50/ +3.50 x180. So, option 4th is not right in both conditions. Please watch the again.

@mandeer8915 Год назад

+1.50Ds/+3.50×180

@optometry-with-samir Год назад

Correct Answer is option A. +5.0/-3.50 x 90° But with simple transportation your answer is also correct.....

@safaaalkhfaji7967 Год назад

Same results if you do transposition

Why ans can't be C?

@optometry-with-samir 4 месяца назад

Watch the video again please... Axis is 90° apart from meridian that's why option C is not correct. Watch this video how to calculate Retinoscopic power: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-TMM4yGalEik.htmlsi=LjSMTpQNkthr2SVD

Eyes are healthy he is having repeated tests to see if he as leber or cone dystrophy he had a prescription test and glasses won't help. his b12 and foliate test came back OK he is really struggling right now with this

@optometry-with-samir Год назад

@@katylewis7118 You said 8 months ago vision was perfect. How do you know his vision was perfect? Did you check his vision then(months age before vision starts blurry)? Write his spectacle power

@katylewis7118 Год назад

He went out one day and noticed he couldn't read street signs and this caused him to book a eye test he said everything Is blurry his optician said his eye are healthy and were concerned about what was happening behind his eyes. I don't know his specitcle power hs had a test which numbs his pupils and they said glasses won't help him
