you might be having the headache not only from the defect in sight but also stress
from your studies students of your age usually complain of headaches
which are due to tension n stress faced during studies n college. So I suggest that you do the following
drinks lots of water around 3 to 4 litres PER DAY avoid fried n spicy foods
homoeopathic medicine belladonna 200 once a day when you have headache helps reduce the headache deep breathing excercise for 15 mins atleast in the morning after you wake up n have water helps relive the stress n also prevent headache
pl continue using specs and use bright lighting for studies maintain atleast 25 cms distance from your eye n book dnt use too much mobile
phn vit b12 n carrots in your diet
the sight problem since it just begun.
