I used to have contact lenses. Well, actually, a contact lens. Trouble was, I could see perfectly without it - just with it I got proper binocular vision. So bascially I would only use it one day a week, on my driving lesson day
The optician said this was fine.
Some years later as my eyes worsened I went up to needing lenses in both eyes, but I told the optician that as I was totally lazy, I just wouldn't bother. So please could I have glasses? It was touch-and-go, due to the nature of my eye problem (with glasses, the lenses were potentially too far away). But it turned out to be fine.
The thing for me at that time was that I could get up in the morning, shove my glasses on, and be done. No faffing with various bits of rinsing before you could put them in, and then taking them out at night and dobbing on this, rinsing, dobbing on that, rinsing, soaking in this that or the other, etc.
I know contact lenses have moved on and so are probably better for the lazy like me now! But I am happy with glasses (especially my current ones, as they are now five years old, and I don't think I've ever had the same prescription for that long before!)
