My experience. Been wearing prescription since a child. Started out shortsighted now gone the other way due to advancing years, into varifocal territory, wear them for reading watching TV, computer and a bit of driving. So most of the day.
For the first time about 3 or 4 years ago I bought my glasses from an independent. Advised they were the best glass and frame...about £350 ! Didn't even buy a fancy style. The leg broke about 2 months in and again 6 months later.
I had always gone for the highstreet versions before this. My more recent go tos have been ASDA 2 FOR £180 (??) I don't treat my glasses very well, on and off through the day, hang them on my collar , never put them into their case but through it all they never fell apart, ( a few scratched lens though) but the first £350 glasses they just couldn't stick the abuse!
Oddly enough my current main specs from asda I've never had so many compliments. Metal large square frame.
Figure out how much you will use them , what you'll need them for, computer, reading TV etc how style driven are you ( I have a friend who spends a fortune on really trendy specs ) , and for me having a second or even cheapo third pair in the car for emergencies is vital. My current situation is that two of my pairs are varifocal and the other just reading glasses. Also have a pair of prescription sunglasses just for reading not varifocal.
Depending on your prescription you might be suitable to use contacts , I found that as much as I hate having to rely on glasses they were less bother than contacts. Stung my eyeball when I accidentally didn't wash my hands of my face cream properly before putting them in which didn't help. Also I suffer with cold sores and was afraid of cross contaminating the cold sore virus to my eye.
Hope this helps...somewhat.
