Accommodation in the eye (focussing) for IGCSE Biology

'So how is it that contracting the ciliary muscles slackens the suspensory ligaments?' I hear you asking, (remotely, via the interweb). I hope I answer this and related q's.

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

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.

Thank you 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.

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

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.

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.
