Re: Dryness in eyes
Vasoconstrictors like Visine shouldn't be used for for than 2/3 times a day for more than 3 days. Artificial tears are probably better to use.
To minimise dryness you may try the followings:
a) Don't direct heaters, fans, air conditioners or hair dryers towards your eyes.
b) Wear glasses when outside on windy days
c) Get a humidifier for your home
d) Remember to blink
