4. The small and highly sensitive part of the retina responsible for detailed central vision
8. The inner most layer of the cornea.

13. These photoreceptor cells detect colour.
14. The iris divides the front of the eye,from the back of the eye. the back of the eye is known as the ....... chamber.
16. The iris divides the front of the eye, which is known as the ......... chamber, from the back of the eye.

15. Part of the eye which is affected by cataract.
17. The 1st refractive structure of the eye that light travels through.
18. These photoreceptor cells detect light intensity.
