Hi, welcome to Health care magic forum.
You are 21 years of age, fave foggy ness of the vision, since 7 days. You used
naphcon from your friend, for red eye. It is more in the night.
It may be due to the
conjunctivitis, night blind ness due to the defeciency of the
vitamin A,or block of the nasolacrymal duct.
Take more of green leafy vegetables, pulses, sprouts.
Never use any drops of others with out prescription. They should not be used after 7 days of opening the seal.
consult an ophthalmic surgeon, for diagnosis and treatment.
Wishing for a quick and complete recovery.
