In myopia,what happens to the power of the eye lens?

Which colour has the maximum wavelength and which has the minimum wavelength? Explain on the basis of wavelength which colour bends the most and which colour bends the least.

$A$ person suffering from an eye defect uses lenses of power $-1 \,D$. Identify the eye defect. Draw a suitable diagram to illustrate how this type of lens corrects the defect. Give the nature of the corrective lens to be used. Also,calculate the focal length of the corrective lens.

The focal length of the eye lens increases when eye muscles

Describe an experiment to discuss the recombination of dispersed light.

Which part of the eye is responsible for changing the focal length of the eye lens by adjusting its thickness?
