For general all round use, which single vision lenses should I choose for my new!

Best Answer - Chosen by Voters

I'm guessing that you are around 40 and you've used glasses before, the 3 options i think you are talking about are: Distance and reading, Bifocals or Multifocals

The first one you need 2 pairs of glasses, one you'll use always and you'll have to switch to the other ones when you want to sees up close

The second one is an old but still used technology, when there is a small squared portion of your distance glasses that you can use to read

The third one is a more advanced technology that it's functionally and cosmetically better, because thay look like normal glasses and they give you far, intermediate an near vision in one

My Advice:
The best is the third choice, but is also the most expensive

If your prescription is not very strong and don't want to spend a lot you can manage to use the first option but using the reading glasses only when you need them without using the distance glasses

Um...Do you mean: which type of lens material do I select?. They have lens materials of different refractive index available. The higher the index, the thinner and lighter the lens will be, but they cost more. So you have two conflicting desires 1] "I don't want to look like a nerd" 2] "I don't want to spend a lot of money". You are going to have to decide where your "equilibrium point" is. Some of the on-line glasses sites have a section where they mention the suggested lens material depending on the strength of your prescription which might be of help.

Added:

If your prescription is pretty weak, you could probably get by with the regular plastic lenses (the cheapest ones) and your glasses won't be all thick & nerdy-looking.

I guess those three options are for when you don't have a prescription. Your prescription tells the optician selling you the glasses what lens you need. When I was younger I was short-sighted and I had specs that I wore all the time. As you age you usually become long sighted and then you need two pairs of specs or, what I use, varifocal lenses. If you are buying your glasses from a place where they just ask questions like that, go somewhere else.
ADDITION
\f you are in UK there is an online supplier that I use. Good quality and much cheaper than opticians. they supply lens to your prescription. If you have been advised to wear them all the time this clearly covers reading, computer and distance! Email me for name of firm; Giving it here is against the rules.

I've been wearing specs for seventy years!

I just got new glasses today and im 14. I have single vision strong lenses for long distance. I have to wear my specs for a more permanent basis. Anyway, i think you should get distance as i have them for my prescription and it seems like you need them for your driving but you mentioned that you read alot, so maybe reading ones as well...
