I have worn glasses since I was 7, then contact lenses from 18 up until my 40s when I developed dry eyes and other problems which meant I had to give them up
Now at 51 am having to consider varifocals
I have quite a strong prescription so usually have the lenses made thinner, prefer rimless styles and due to allergies have to have either titanium or stainless steel frames
My current pair are also transitions as I found that cheaper last time than buying a second pair even with the offers around
I've tried 3 local independents along with vision express and specsavers
Cheapest quote I've had was around £400 dearest £600+
That was not for custom varifocals but not for the very basic ones either
