Unfortunately the eyes don’t recognise the difference between cricket or a mathematical table as far as the light entering is concerned. It registers pixels, brightness, photons and not the content. So part of the eye care, especially since you have reading glasses, is to reduce the screen time, blink often and give the eyes enough time to rest.
Also playing cricket develops us in many ways but watching cricket is mainly entertainment and it is best to keep entertainment within limits and focus more on development in different directions which is possible during student days. Later it becomes difficult as nature becomes relatively hardened.
Affectionately,
