I have Transitions Lenses on my glasses. I've had these lenses since 2009 I think. I don't use them much--mainly when my contacts are bothering me. But I've noticed that when I go outside, they barely darken (they used to get really dark).Is it time for new lenses or is there a way I can get them to start darkening better when I go outside?
I literally only wear them when my contacts are bothering me (a couple times a month), so getting new lenses wouldn't be very cost effective for me.
