I would think it would be about the same length of time as it is for eye exams. Most doctors recommend a yearly exam for most people, unless they are having problems that cause rapid changes in their prescription.
I was speaking to a young man who hadn't had his eyes checked since he was 10, and he's now 16. When he had it chacked, his PD had changed 5 mm in 6 years. He was told that most people wouldn't notice a PD change of less than 3 mm. His problem was that his facial structure had changed so much that his *vertical* distance had changed and he was no longer looking through the optical center (OC) of the lenses. It was making him see rainbows (chromatic abberation) through the lenses. -=# Firewalker #=- On Mar 15, 6:46 pm, BDO <[email protected]> wrote: > I have PD measurements for my 11 and 13 year old daughters that were > taken by an optician using a pupilometer less than a year ago.
