U are great bhai

[@risingaayush7995]

Great explanation sir

[@dineshmandal2335]

Very good explanation! Thanks Sir

[@sanjayaam]

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.

[@wechillars9130]

You are awesome sir ......!!!!!!!

Itna acha explanation only in a breath 🤐

[@infobasic99]

Ye vedios dekhne k baad physics ab achi lgne lgi h

[@ManishKumar-jl2vl]

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]

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

[@adghg]

Super 👍 sir

[@asifsaif7019]

Your explanation is good

Thanks sir

[@dineshupadhyay384]

You are best

[@knowthefacts5872]

Really good explanation

[@Deveshnigam777]

Sir in last What causes this problem [myopia] eyeballs big and lens thick kyo ho jata h [Hypermetropia] eyeballs are small and lens are thin why these problem sir please reply 🙏🙄

[@sandhyabanka7520]

Good question!!

[@mikelarusso7597]

Due to. Movement of ciliary muscles

[@mikelarusso7597]

R UK Indian?

[@mikelarusso7597]

Can I talk in hindi?

[@mikelarusso7597]

Open NCERT see the concept of dark room and light room u will understand
