6. Drink carrot juice as often as possible (preferably every day). If you want to maximize the effects, add one or two drops of olive oil. This will not spoil the taste, but it will help you absorb the good elements of carrot juice more efficiently.
9. Try the Indian Trataka exercise for the eyes. This will help your eyes and mind stay focused.
Sit in front of a small stationary object placed in an open space (a candle, for example). Focus your eyes and attention on it. Try not to blink. Try to get a firm and detailed picture of the object in your mind and memory.
