Vuity is an eye drop that makes the pupil smaller. Much like increasing the F-Stop on a camera, the smaller the pupil, the greater the depth of field. Vuity can improve the near vision for patients with Stage 1 DLS. The effects from 1 drop of Vuity typically will last about 4-6 hours. Some patients may experience a slight brow ache. Because the drop makes the pupil smaller, less light enters the eye. This may cause dimmer vision, particularly in low light situations such as driving at night. If appropriate, Dr. Hamilton may suggest you try Vuity in the office to see if it makes sense for your particular situation.
