""Vizz and the drug that has come before it, Vuity, have both worked on the same structural function; they cause your iris, or the colored part of your eye, to get smaller and smaller," Dr. Johnson explained. "As your pupil gets smaller, it becomes apparent that it is like looking through a pinhole, and your depth of focus therefore increases.""
""It will work much better for the younger, 40, 50, 55-year-old patients than it will for the 60, 65, 70-year-old patients," Dr. Johnson said. "Because they have less of a need to focus. By the time you get to be my age, your natural ability to focus is all gone. Therefore, the pupil would have to be made obsessively smaller and smaller. And if that pupil becomes too small, we begin to lose the amount of light that gets into the eye, and now you are going to have a 70-year-old who can read, but who can't drive when the sun goes down.""
Vizz is an FDA-approved, once-daily prescription eye drop designed to improve presbyopia, providing near-vision improvement for up to ten hours after one drop in each eye. The drops act by constricting the iris, creating a pinhole effect that increases depth of focus. Vizz and Vuity target the same structural function of making the pupil smaller. Pricing commonly listed is $79 per month for 25 doses or $198 for 75 doses, though pharmacy prices may vary. Common side effects include eye redness, headaches, and dimmed vision. Effectiveness is typically greater for patients in their 40s and 50s than for those in their 60s or older. Consult an eye care professional to determine suitability.
