Been wearing them since I was a kid. Got cataracts and astigmatism in both eyes.
Went for an eye test a year ago and got told I needed Varifocals. Presumed this was the optician trying to scam more money out of me, so went and got a second opinion...and the 2nd optician told me I needed varifocals too.
That was a sharp shock to the system, to remind me im not getting any younger. I got varifocals with reactalite lenses and they cost a fortune but I'm so glad I don't need to faff around switching between normal glasses and sunglasses anymore.
So, if you do need glasses, I would highly recommend getting reactalite lenses.
