Dear Shashwat,

There is no quick fix to cure eyesight immediately. If you go with medicines or home remedies, it will take you minimum 2months to start seeing the results. As your vision is -6.5 which is myopic defect or short-sightedness, that can't be cured in short fixes.

If you have enough time, you can try home remedy which is-

Take equal quantities of:

Mishri (granules of Sugar),

Badam (Almonds),

Green suanf (Fennel Seeds)

Grind these well in a mixer. You will get a powdery texture. Take one tablespoon of this mixture with glass of warm milk everyday. This remedy can take 1-2 months to start giving you results. For curing -6.5, it can take huge time as well.

Else, if you don't have sufficient time, you can consider doing Laser operation as well. This can be considered as a quick fix to cure your eyesight.

Hope this helps.

All the Best!!
