I've amblyopia (lazy right eye) i did the vision medical check and it was ( -10 ) out of ( 12 ) then i used to wear a medical glasses for over 6 months but the right eye's vision did not change at all, can this condition of lazy eye cured and how?

The treatment depends on many factors and be corrected by glasses if caught early. You have to see an Opth. who specializes in that and he/she will diagnose the nature and extend and treat you based on that. Without that no prognosis about cure can be made. Hope you get better.

If by lazy eye you mean the right one does not line up with the left & point to the same spot, sometimes surgery helps. It often develops when a weaker eye drifts off giving a fuzzy or double image to the brain. The brain loses control & eventually ignores the image provided. Surgery can line them up, but may fail if the vision in the weak eye is too poor to hold it in position.

Amblyopia is a condition where the eye does not form proper connections to the brain. It is permanent and irreversible after approximately age 7. After this point the damage is not correctable.

Would recommend an opthalmologist ho deals with lazy eye ( that may be a pediatric opthalmologist or a developmental optometrist https://www.thevisiontherapycenter.com/discovering-vision-therapy/bid/82287/the-shocking-truth-about-lazy-eye-correction-for-adults https://www.theverge.com/2021/10/20/22736894/fda-vr-tv-movies-treatment-lazy-eye-amblyopia

Amblyopia or lazy eye is when the vision in the eye does not fully develop. It can be improved in the first 5 years of life. Usually after the age of 5, even with treatment the vision does not improve.
