    eyesight-related vocabulary

    Let's say you're short-sighted and you need to wear glasses or contacts. How to say what kind of correction you need?

    My ...... is -3,5.

    Most of us wear glasses, nyota, but hardly any of us understand our optical prescriptions.

    Personally, my right eye is better than my left and my eyesight is better for distance than reading.

    That's all I know about it, and all I need to know.

    I think you could say:
    I'm (minus) 3.5 dioptres in my left eye and (minus) 4 in my right eye.

    Also:
    I need (minus) 3.5-dioptre lenses in my left eye and (minus) 4-dioptre ones in the other.
    or
    I need lenses of (minus) 3.5 dioptres in my left eye and lenses of (minus) 4 dioptres in the other.

    In the case when both your eyes are of the same dioptric value, you might say:
    I'm (minus) 4 dioptres in both (my) eyes.

    Re: eyesight-related vocabulary

    Thanks engee30. What if I'd like to ask somebody a question (assuming the context's known) without referring to dioptres. Or even if I was to use the word, what would be the best way to use it?

    What dioptres do you wear/have? How many dioptres do you have?
    What are your corrective lenses values/powers?
    What's your gradation?


    I mean, there *has* to be a pretty common way of asking about it even if you're not an expert and you don't really know or need to know what the numbers are.

    I don't think that there is a 'pretty common way' in BrE. I am with Rover - most of us don't understand these things, and we don't talk about them in any detailed way. Really!

    engee may be right when he says, "I think you could say: I'm (minus) 3.5 dioptres in my left eye and (minus) 4 in my right eye.", but I have never heard anyone saying anything like that. Indeed, I have to admit that if you had asked me out of the blue what unit was used, I would not have remembered the word 'dioptres'.

    Re: eyesight-related vocabulary

    How interesting. You see, I kept going on about it because in Polish you'd hear the question quite often (once you've started talking about glasses). Most people recognise 1.0 is no big deal while 6.0 is quite a lot. So I assumed there must be a common way of asking about it in English too. Assume nothing! But you're right, it's not something you really need to know.

    So, going downstream with the others participating in this discussion, I'd advise you, nyota, to use the following appropriately:

    I'm nearsighted/shortsighted. (a person saying this is sure to be wearing a pair of glasses with lenses of the negative power of dioptres; used by a person with myopia, ie nearsightedness/shortsightedness)

    I'm farsighted/longsighted. (a person saying this is certain to be wearing a pair of glasses with lenses of the positive power of dioptres; used by a person with hyperopia, ie farsightedness/longsightedness)

    PS. But for my younger brother, I'd have never known what dioptr(i)e is.

    A-ha! So the word 'power' is somehow in use.

    Also, I've just googled something that might work quite nicely and that sends us back to 'prescription':

    For people with strong prescriptions, high index plastic lenses are a great choice.
    No one will ever guess how strong your prescription really is!

    So a simple How strong is your prescription should suffice.

    Engee30, I know what you mean. A lot of bats in my family, so I did know the word but I hardly ever use it.

    Yes, and in my case, the only moments when I hear someone using such sophisticated vocabulary about glasses are when my brother comes back from his optician (once every six months or so) and informs us all of the progress or regress of his problematic eyesight.
