So sure eniugh when I hit 40 my eyes started to go and after boucing around with a few of the "off the shelf" reading glasses I eventually settled on my own prescription based pair.
So here is the story, I ordered some aditional reading glasses from one of these companies based 'somewhere else on the planet' and received an additional pair of reading glasses. Great!
After I trod on my spare pair and ordered a replacement from the same company I was surprised when they came back and apeared blurry. Bit of a revelation when I looked up though as objects that I had previously thought were sharp were now 'pin sharp' (I had ordered long distance instead of reading lenses by mistake)
So (don't worry I am getting there) this was all fine for a while and I even occasionally pick up the long sighted pair for watching HD films.
Then I got a new laptop that supported 'Intel WIDI' and proceeded to set up a shared monitor between my laptop and TV on the other side of the room.
All worked well and for a while I sat there with my reading glasses perched on the end of my nose such that when I looked at my laptop I could see eveything in focus, and when I looked up I could see everything on the TV (albeit sharp but not 'pin sharp')
So I decided to try varifocals and they arrived this morning.
I have to say they are a bit of a let down - I guess I was expecting a miracle but what you actually get with these lenses is a fairly small "sweet spot" This guy explains it better.
So I guess I will endevour to persevere for a while.
