What is Presbyopia?

About Presbyopia:

• It is an age-related condition in which the eyes gradually lose the ability to focus on nearby objects.
• People usually start to develop presbyopia at around the age of 40. According to doctors, spectacles are one of the most effective ways to manage the condition.
• How does PresVu work?
  • The active ingredient — chemical compounds in medicines that have an effect on the body — in PresVu is Pilocarpine.
  • The compound contracts the iris muscles, which control the size of the pupil and help humans see things clearly, thereby enabling one’s eyes to focus better on nearby objects.
  • PresVu uses “advanced dynamic buffer technology” — essentially, a base solution — to adapt to the pH level (a scale used to measure how acidic or basic a substance is) of tears.
  • This ensures that the eye drop has “consistent efficacy and safety for extended use, keeping in mind that such drops will be used for years at a stretch”.
• PresVu is a prescription-only medicine and its impact is unlikely to last beyond four to six hours. It should not be used by people who have inflammation of the iris.
• Regular use of PresVu may lead to itching and redness, eyebrow pain, and muscle spasms in the eyes.
