I made a 'late' appointment today for the Optometrist and noticed in my packet that if you wear RGP (hard) contact lenses, they must be removed 21 days prior to the examination. However, when I called the doctor, the receptionist told me that I only had to remove them 3 days prior, regardless of it being soft or hard contact lenses. Which one should I believe? Because my scheduled date is less than 21 days away from the day I started wearing glasses.

Thanks.
