Brent - the trouble is that Phillips "claimed" that they were Shade 3/Shade 5. In order to meet the ANSI standards for claiming shade number protection, there are very stringent transmission numbers for IR transmission that absolutely HAVE to be met. The original information I posted on the Aura Lens website, and the follow up test information posted on The GLDG shows that the Boroscopes DO NOT meet the ANSI standards for either Shade 3 OR Shade 5. Phillips cannot claim a shade number equivalency for these filters because they do not meet the ANSI standards for those shade numbers.

The biggest problem with IR is that the damage is cumulative. It builds up over time. Every person has a different threshold of damage at which point the damage begins to affect the physical structure of the eye in an obvious fashion.
