What is causing the glasses to be cloudy?
Q: I have Progressive transition glasses with an anti-reflective layer which I am not sure really works.
I notice that after a year to 18 months the glasses start to seem cloudy especially when I am in a large store with the overhead lights.
After a couple years this cloudiness is also noticeable outside in regular sunlight. I do not have this happening when I am wearing my computer glasses which I have taken to using when not driving since they never seem cloudy even in a bright store.
What causes this and is there anyway to restore the lenses or keep this from happening?A:
There are several things that could produce this symptoms.
First, your lenses: if you wore them for a longer period, there is a chance that the anti-reflective layer is slightly damaged from continuous cleaning, this is happening when you use other cleaning stuff than recommended.
There will be small scratches on the surface that bend the light so you will have blurry vision.
The other thing is your prescription: after years of wearing the same prescription, there is a chance that it changed, so maybe is a good idea to renew it.
Maybe your diopters had changed and you need a new prescription.
Eather way, it is a good idea to go to an optical shop and check your glasses and your prescription.
If the lenses are to blame, you need to know that changing the layers on them is more expensive sometimes that changing the lenses, but you have to ask in that shop.
Hope this helps,
