Matte white O matter

[Freezedry]

Hi, does your matte white o matter frame turns yellowish after some time?

I have one flak 2.0 pair that I didn't quite use and kept in cupboard all these while. Was surprised it turned slightly yellow. Is that normal? Can I restore it to the original colour?

Thanks

I have had some matte white Flak 1.0's for 4 years and use them frequently on baseball fields. They are still white though the matte finish has worn to a more smooth polished finish.
