Should i put my glasses every time or only when i need it?because when i putted it every time.it become worest.

Glasses are to help : Wear you glasses all the time if you want to see better. Wearing glasses will not itself make you vision get worse.

When needed: If your prescription isn't too strong , it's fine to wear your glasses only when needed. If your nearsighted they'll help most at far distance; if farsighted, they'll help most for small print up close; if astigmatism at all distances, but not mandatory for mild prescriptions.
