It depends on your current condition. It is easier for prevention at earlier stages and age.

Environment that is brightly lit can help reduce myopia. One common myth that my group found was that looking at trees or 'green objects' does not actually help.

Lasik can help reduce myopia, hyperopia and astigmatisation. This area I'm not too familiar so better to check with a professional.
