    I've had the same glasses for about 10 years now. I had 2 pairs of
    glasses made at Wal-Mart in 1998. One for distance, and one for

    Well... I lost the "distance" glasses and still use the "reading"
    ones. Funny thing is... the reading glasses now seem to not only
    improve my reading vision, but also my distance vision.

    Here are my questions.

    1- How important is the size of the lenses to filling a prescription
    correctly. My lenses are about 1 3/4" wide and 1 1/2" high. That's
    OK... but I would prefer a smaller size lens the next time.

    Is that possible? A much smaller lens? I do have some astigmatism in
    both eyes so I was wondering if that factors in the lens size. Is
    there any benifit for a larger lens? Such as a better field of

    2- Is there a trend away from square or rectangular lenses? It seems
    I see more and more lenses that are oval or have some "roundness" to
    them. I like a "squarish" kinda lens.

    Anyone who can shed some light on my questions would be very helpful
    to me.

    Thanks in advance.

    Sounds like time for a new exam, and maybe new glasses.
    I'll see if a can shed some light. I am not a vision professional, of
    any kind, but I have worn glasses, of various types, strengths and
    shapes since fourth grade. I am now 58. I have seen big lenses, small
    lenses, round lenses, oval lenses and square lenses. As far as I can
    tell, it's all cosmetic. Whenever the optician is pushing something,
    the only explanation I can get is that anything else won't look right.
    I have gotten glasses that were unwearable (think -12D huge lenses, as
    that was the style). When I said that I wanted something different, the
    optician said they wouldn't look right. I suspected that they had
    nothing in stock.

    If you get a progressive lens (distance and reading in the same lens) it
    helps to keep the lens size as large as aesthetically possible, but many
    people have very small progressive lenses. It is just a trade-off of the
    size of the viewing area of the lens versus aesthetics.

    You can usually go fairly small with a single vision lens without a big
