Want to know how the eye focuses or accommodates?
This video goes through the physics of accomodation, how the eye adjusts in order to produce a sharp image on the retina.
It also covers long and short sightedness and how to fix them.

6:31 his pronunciation of "fatter" called me a peasant in so many ways

how would you pronounce it? I could have said 'thicker'. but I assume with the large proportion of american videos out there this aussie version of it sounds 'different' 🤓

i was kidding, i actually loved how you pronounced it

Good job sir I undestood it very well..your eyes looks smaller so you have got short sightedness right?

It is a very god illustration for the process. Could you please illustrate the Bates method for us as well? Bates method helped lots of people but still there is no a good illustration done. I think it is going to be easy for you as you have all the craphics prepared. This method is based on phisics of the eye and shows the work of an eye as even more wellthought.

+Oleg Teplyakov Not familiar with the Bates method (yet), so I'll 'look' into it (haha). I teach the content in Biology lessons so will be applicable. Stay tuned

Hi! How did you overlay the eye on top of the PhET animation? I am giving a talk on optical physics next month and would like to do something similar :)

The animation is on PhET and now html5 I then used an interactive software app that allowed for desktop animation. In my case Promethean Inspire. It used to keep the annotations whilst manipulating the animation but unfortunately later versions have limited this. You could look for alternative interactive whiteboard apps that still have that functionality. For example Openboard
