GCSE Biology - How the Eye Works (Part 2) - Accommodation #32

This video covers:
- How the eye focusses light onto the retina, which is known as accommodation
- How the ciliary muscles and suspensory ligaments work

Easy way to remember if you are struggling to understand:
- NEARBY: Suspensory ligaments SLACKENS - Cilary muscles CONTRACT (remember it as SS and CC)
However, when you think about it for far objects, you can just think of the opposite. (Suspensory ligaments taut, cilary muslces relax)
Hope thats helps!!🎉🎉

i was waiting for the "anyway... that's it for today. Hope you enjoyed and i'll see you in the next one"

I want to thank you sincerely for ALL THE HARDWORK for the great drawing, effects, especially how amazingly all is understandable in chronological way which makes it more easier to understand.God bless you with all great things in life and AFTER LIFE ✨❤️

Ophthalmologist here. If the eye is long- or short-sighted, it’s not always the lens’s fault. Short sighted people often have longer eyeballs, so the focus falls short of the retina. Long sighted people often have small eyes, so their focus overshoots the eyeball. It can also be the fault of the cornea, which can be too flat or too curved

sir u have just made the life of my online-schooled med student ass easier. thank you so much 😭

[Delluxe]

Please keep on going you truly are the savior and the hero of our depressed students thanks again :)

[abiramims]

i just really wanna thanks from my heart. I watch the videos topic vise and try to answer the topic questions which is given your website and then try to answer past papers. i really appreciate your hard work in segregating the questions topic vise and the videos for each chapter.

this channel is so underrated, thanks sm!!!!

Eye can see your success in education! ;D

[ramlan]

I legit have a bio test tomorrow and this helps a lot, hopefully I remember it tomorrow...

From a medical student perspective, you have the best video on eye correlating both anatomy and physiology at the same time, and the best part of your video is animation because eye physiology is something best understood by visualisation. I encourage you to start making videos of physiological concepts for medschool.

hello your helping me with my biology exam cheers lad

[julip_bear]

My gcse is in 2 days, thank you! <3

[wizardom]

The clearest explanation I've been able to find, by far!

[areebakhalid]

best educational platform ever it is the best for all levels

1:52 eye don't think fat-shaming is very nice 😂

[ConquererTanzi]

I have a bio xm. And everytime i have an xm I rewatch these videos to freshen up my mind!

[ayo]

This video made it so much easier to understand. Thank you!

[mizginalgul]

Thank you for helping me revise for my science test <3

Hey cognito!
Although I am not particularly sure, aren't the diagrams at 5:40 the wrong way round? I would imagine that the relative lens of a long-sighted person would be significantly less fat than the diagram illustrates, considering that the inability to view close objects is derived from having a less elastic lens(thinner).
