Want to wear eyeglass frames with dummy clear lenses--okay?

    I would like to buy frames with clear non-prescription lenses just
    because I think I look better with glasses, and to protect my eyes from
    dust and other things.

    Are the plastic dummy lenses that are in the frames you see on display
    in the Optical store sufficient for this? Do they allow clear
    undistorted vision? Are they shatterproof, in case somebody aimed a
    slingshot at my eye? Are they scratchproof?

    In other words, can I just walk into a store and buy a frame with the
    plastic lenses that are already in it? Or do I have to have them order
    special clear lenses that have these qualities?

    Thanks for any information.

    Those dummy lenses in frames sold in opticals are not for wear. It's
    only for demo purposes. You do need an actual spectacle prescription
    even if you are emmetropic (ie without any refractive error).

    If you're going to use them as sunglasses, of course there are many
    good otc (over the counter) sunglasses available. But again, if
    as you stated, you want clear untinted lenses you can't get them
    without prescription lenses.

    Thanks for your replies. Why are the dummy lenses unsuitable? Is it
    because they aren't clear enough, and distort your view? Also, are they
    not shatterproof? I'm not looking for sunglasses, just want some clear
    nonprescription glasses.

    Thanks again.

    The main purpose of the dummy lens is so that the optician can mark the
    fitting height on the plastic with a marking pen in order for the real lens
    to be cut properly. The dummy lens also holds the frame together and keeps
    it from bending out of shape.

    These dummy lenses are very thin and will scratch easily. I suspect (but
    don't know) that the dummy lenses are very susceptible to shattering into
    very sharp pieces, and maybe more dangerous than having no lens. But it is
    also possible that not all dummy lenses are the same material.

    If you want to know whether they are clear and distortion free enough, try
    them out yourself.

    If you want a true shatterproof lenses (or highly resistant to shattering),
    you will need polycarbonate or Trivex lenses.

    I think most people would be able to notice that the dummy lens is not real,
    so that might another problem (but I don't really know why you want them).

    As someone who wore glasses for 35 years, I can tell you that they aren't
    a lot of help against dust. Sand maybe, but not dust.

    After my first cataract surgery, my doctor told me that I needed to wear
    eye protection (glasses) for some period of time. I found
    non-prescription bifocals at the drugstore. They had no correction in the
    top, which was most of the lens area, and a minor reading correction in
    the small segment on the bottom. This was exactly what I needed. These
    glasses were probably less than US$20.00. Be aware that a plain frame
    that you buy at an optical place will set you back anywhere from US$75.00
    on up. Blank lenses will run you another US$50.00.

    I investigated getting a blank lens put in my existing glasses (your
    vision changes as your eye heals from the surgery, so you can't just get
    correct lenses right away). They said that it would be US$42.00! (I had
    a high index lens for the other eye).
