In short, no. It is a misconception that the colour of non-browning glass will remain completely unchanged when exposed to radiation. After it has been irradiated non browning glass will change in colour, losing a little bit of transmission at the blue end of the spectrum. This change is relatively small and after the initial shift the colour will stabilise. The non browning glass will then continue to maintain reasonable transition until such time as it exceeds its radiation rating. In the case of Resolve Optics non-browning lenses, they are rated for 100,000,000 rad so depending on the level of radiation they are exposed to daily you could expect the lens to have a life of around 10 years. By contrast – standard glass will steadily become darker and darker, very quickly becoming unusable if not losing transmission all together.
