A -xA0-human eye has a converging lens behind the iris- held by the ciliary muscles- When tension is applied on lens by ciliary muscles- shape -convexity- of the lens changes and image is focussed on retina- These ciliary mucsles form ciliary tube- thus focussing is done by change in the convexity of lena by ciliary tube-
