I have short-sightedness with degree of 150-200 for both eyes. How can I improve my eyesight instead of wearing glasses?

Options... For correcting near-sightedness include glasses, contacts, and surgeries. Surgeries can be broken down into two broad groups: laser-based surgeries such as lasik or intraocular-based surgeries such as refractive lens exchange. Your near-sighted prescription should be stable before considering any type of surgery.
