Accommodation in the eye (focussing) for IGCSE Biology

[@Conquerer777Tanzi]

This is the type of biology teacher everybody in the world needs!

[@honorcolling4687]

youre the only person who has made me understand why the contracting slackens the suspensory ligaments thankyou so much youre so clever

[@TomDare]

Really pleased it helped. Thanks for commenting!

[@melaniebrown8444]

your explanation of the contraction/relaxation of the muscle/ligament was so clear; I had read about this several times and couldn't work it out. Thank you.

[@softwarrior1512]

Found this today,but thank you,you helped me understand how the lens works with the objects which are far and close

[@abodeyabyad4566]

Thank you soooooo much for doing these videos , much better than my teacher and my text book , they make everything simple and clear , unlike the textbook and my teachers.

[@toomashanso187]

how weird, i was just lying in the shade of a tree in the serengeti watching wildebeest, good luck to everyone doing their igcse tomorrow!

[@pijushbhowal6214]

Тоомас Хансо classy English ha

[@annymus4502]

Wait, really!? Or is it sarcasm?

[@stevesmith3517]

there reallly was no need for that comment but ok

[@katusiimekkervin]

BEST INFORMATION. I HAVE LIKED IT

[@katelevett9850]

As a mature student, I had to get a C for biology when it wasn't one of my options at school. My work commitments meant that I had no choice but to self study and your videos have just been amazingly useful. Fingers crossed I did enough on paper 1 on Tuesday.

[@HK4718]

how did you get on?

[@king_apex3291]

Thank you; you have explained it better than anyone has ever

[@otiebrown9999]

All normal eyes, continously monitor micro-blur on the surface of the retina. It is a superior feedback control system, with a time-constant of about 1/3 second.

[@josephwub]

I've never had so much fun learning

[@rajikannan4857]

dude my text book is nothing compared to this video of yours.TYSM!!!!

[@ipv2000]

[@otiebrown9999]

Great insights!

[@adernain]

Does the accommodation decrease when someone has Myopia? So lets say someone has 4 Diopter Myopia, will that Accommodation become 10 instead of 14?

[@MuhammadHussain-ry9vh]

thank you very much for these videos! pease can you try to do the whole biology igcse course, my boards are next year and you teach better my teacher and book... thanks

[@dduda2894]

Can you do f211 via please,tom

[@TomDare]

Shazia Nawaz Trying to get videos out as and when time allows. Also, you are the last year that will take F211, other than retakers, so we'll probably focus on the new syllabus from next year. There should be some F212,3 &4 videos that can help on the playlists. Hope that helps.

I was actually watching wilder beast xD

[@sebbe91]

Great

[@GUCCI-hz8ow]

Hello Tom I'm biology teacher too. I have a question. The ciliary muscles of a normal eye are in their most relaxed state as then the thickness of the lens increases, thus increasing focal length. So how you say the ciliary muscles are contracted when we look at near distance? 🤔 I think when we look at far distance then the ciliary muscles contracted

[@watermelonman4439]

BRO I WAS LITR WATCHING WILDEEBEEST

[@νικμαστεροφσιτυσιτυ]

light is commin like a mopet 2:03
