I've been using reading glasses for nearly 5 years now and it'll take about 2 years before I go to my eye doctor to consult once again and have it changed. I prefer branded eyeglasses but there are also cheap eyeglasses that I saw at the optical shops for those that don't have enough budget.
I sometimes get irked when people (not so closed ones) tactlessly tell me that the reason why I'm wearing glasses is because I sit too much in front of my computer all day long. It may be true at some point but the comment is not appropriate for them to say to me as it is sending a different meaning to me.
Anyway, I can't read without my glasses on, so I make it a point to check if it's in my bag all the time wherever I go.
