😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭 where this video was ... i was in this confusion from 3 -4 months that how our lens change shape how the image is formed behind or in front of retina..... thankyou sooo much sir ...your teaching style is awesome 💯💯

@mogli8963 5 лет назад

Make lecture related to *Neet* exam!!

@sanjayaam 2 года назад

Superb explanation of the concept. I was searching all over the web and nothing explains it like you have done. The important point is that when the eye lens is in unaccommodated position (looking at a far away object) the focal point is such that light from far off objects is focussing in front of the retina thus causing blur. *But* when looking at near objects the eye accomodates and moves the focal point around so that the image focusses on the retina. What this theoretically means is that people with myopia only need glasses when looking at something distant as when looking at something close like reading a book do not need glasses. This point is significant as today there is no such guidance for myopic people. They are asked to wear glasses all the time even when doing up close activities like reading. And in doing so they end up focusing the image behind the retina thus causing what is called hyperopic defocus which results in elongating their eyeball (esp for young people whose eyes are in growing stage) which results in further increas in the myopia power.

@pratimavinayak8205 Год назад

My question is why don't a myopic eye sees the objects smaller as the concave lens used forms a smaller image

@pratimavinayak8205 Год назад

And will there be any change is image size formed by the myopic eye alone and when the concave lens is placed infront of it while viewing nearby objects

@pratimavinayak8205 Год назад

Anyone pls tell. I m very perplexed

@Supriya-hn1ts Год назад

Pls tell your question in proper way I don't understand u said myopic eye doesn't sees smaller while using concave lens it's wrong myopic eye sees smaller due to using of concave lens but in our eyes convex lense present it so we doesn't see more smaller while a person have myopia and use the concave lense

@ManishKumar-jl2vl 4 года назад

Is it possible that ciliary muscle cant stretch or contract properly and thus causes these two defects or is it due to defects in the eye lens. Plz enlighten me

@amritaganguly2531 Год назад

Yes , it's possible. It's occur at old age . This is called presbyopia . It can be corrected by *bifocal lens*.

@vishvjeetsingh2168 5 лет назад

Hlo sir I have one doubt, in high conversing power of eye lens, is the near point shift less than 25 cm

@poojapandey2717 5 лет назад

No, it remains same b'cauz when the eye lens become highly conversive then the eye defect called myopia arises in which we can't see the distant object. In this eye defect we can see the near objects clearly.
