What is the difference between progressive lenses and progressive glasses

[@rajeshtripura725]

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

[@optometry-with-samir]

Here we are discussing about the mechanisms of Optical Cross.. Watch Details about "Retinoscopic Power calculation" here: kzbin.info/www/bejne/in6wZax9ltF4n80si=M0PEBUgPlPBpGEeb

WD subtract karna padega na ? Kaun sa procedure hai jisme WD subtract nhi karna pade😊

[@optometry-with-samir]

Here, we are not discussing about Retinoscopic power calculation. Here we explaining how to convert spectacle power into optical cross and optical cross into spectacle power. Watch how to calculate Retinoscopic power in this video: kzbin.info/www/bejne/in6wZax9ltF4n80si=PSOjZns9yiVsRBBr

[@santhieswari8537]

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

[@optometry-with-samir]

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.

[@prasannashetty2526]

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

[@optometry-with-samir]

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

Can you explain What serve bilateral ganglion cell depletion is please

[@optometry-with-samir]

Ganglion cell depletion in the retina can be caused by a variety of factors, both genetic and acquired. Some potential causes of ganglion cell depletion include: Glaucoma, Optic nerve diseases, Retinal Degeneration, trauma, aging, vascular disorder etc...

My son is 19 an his vision went blurry 8 months ago before this vision was perfect his vision is 6/240 in his better eye. 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]

@@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]

@@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

[@optometry-with-samir]

@@katylewis7118 You should consult with a retina specialist. Even if retinal issues are there vision therapy can improve his functional vision.

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: kzbin.info/www/bejne/in6wZax9ltF4n80si=LjSMTpQNkthr2SVD
