What is the life expectancy of Transitions VI lenses?
The performance life of Transitions VI lenses will generally last the lifetime of the prescription. While it is normal for there to be a small loss of photochromic performance over time, with normal usage, this is generally not perceptible by the wearer. Because most Transitions lens wearers become loyal, repeat customers, chances are you will sell them a new pair long before their Transitions VI lenses have any perceptible change in performance.
