My friend u need to understand what is myopia. Its basically elongation of eye balls so that the image is not getting clearly focused on retina. This could even be hereditary.
Spectacles are the treatment of choice for your age. Although eating healthy and a nutritious diet may help, but do not consider this as a sure shot treatment. No ayurvedic eye drops or medicines can cure it completely. Please do not fall for any such scam. Myopes are said to be smart people, not to mention all the cool glasses and frames available nowadays which are very trendy. 😊
Next Steps
Once your spectacle power is stable, u can opt for LASIK / SMILE and get rid of glasses after the age of 20 years.
Health Tips
Use ice packs, avoid using mobile after switching off the lights in your room and maintain minimum 40 cma distance between ur eyes and any digital screen.
