Is this possible to change eyes colour permanenet and to make fine eyesight? ¿

Can't. No. There is no elective medication to change eye color. In individuals affected by the disease glaucoma, a therapeutic agent used to lower eye pressure, called a prostaglandin analogue, has a side effect of changing iris color. If you need glasses to see well, you could discuss with an ophthalmologist wether contact lenses are right for you. These can be colored.
No. Iris color cannot be permanently changed ( although this has been reported with the use of certain lash enhancing medications). Vision CAN be improved in some people with outpatient surgical procedures. .
