The Human Eye September 4, 2015Posted by Gareth in : Science, Welsh , trackback
This great interactive resource from UK opticians Vision Direct focusses (no pun intended) on the human eye. There are two main sections. In the first you can click on the various parts of the eye to learn what they are called and what they do. In the second you can explore how the eye allows people to see. You can see how the iris alters the size of the pupil depending on the brightness and also watch how the lens changes shape to adjust the focus length.
It’s great to see that the resource is also available in Welsh…
