Hi there,

Is the following sentence correct, especially the use of the word 'practice'?

You should play more sports in order to have more practice on your eyes.
For example, you may play table tennis which requires a high determination of where the ball goes, so that you can have your eyes trained.

No, you can't 'have practice on your eyes'.

You can practice using your eyes, I suppose, but even that sounds strange as you are using your eyes - praticing with them - all the time! It would be more realistic to practice a certain skill (involving your eyes) rather than just using your eyes. For example, practicing hand/eye co-ordination.

I would say for your eyes. I am not sure if people say like that.

An another way to say:
You should play more sports in order to have more eye practice.
