Further queries: samirsutradhar0@gmail.com
Why ans can't be C?
Watch the video again please...
Axis is 90° apart from meridian that's why option C is not correct.

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
@@optometry-with-samir He didn't have an eye examination but says he didn't struggle to see or read he passed his all his digger tests first time he was a apprentice groud worker and was able to read directional signs whilst having driving lesson. 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

You should consult with a retina specialist. Even if retinal issues are there vision therapy can improve his functional vision.
DHA past papers py videos banai sir . Everyone watches those videos. The book is pretty expensive, i think 69$ but it will help a lot to poeple and to this channel. *Prometric Optometry book*
