Good: Alaway (Bausch & Lomb) One drop twice a day, priced around $14 for a 10 mL bottle.
Best: Pataday (Alcon) Twice Daily, blue label, around $16 for a 5 mL bottle.
Pataday is also available as a more concentrated Once Daily, red label, around $18 for a 2.5 mL bottle! 2.5 mL is a surprisingly small amount.
For someone with mild symptoms, Alaway is a good value. For more significant symptoms, Pataday Twice Daily is a great choice. We rarely see the need for the more concentrated Once Daily, especially for those who get two drops on the cheek for every one in the eye!
