We sell Protect-A-Lens products in smoke and clear. Smoke can be used for the every day restorations with patients that have been around for awhile. Clear can be used for new patients when the Dentist wants to monitor the patient’s pupils to make sure the patient is not having any reaction to the anesthetic. They can also be used when the dentist offers TV while he is working. The patient can see the TV and the dentist is confident that debris will not get in the patient’s eyes.
