[vsnet-chat 12] how many of us have ____ eyesight?

[Fraser Farrell <fraserf@dove.net.au>]

G'day all,

I have received several responses on this question so far.

Unfortunately (for statistics) nearly all of the responses have come
from observers who _do_ use spectacles/contact lenses.  Are the
observers with perfect eyes too busy observing?

I plan to post a summary of your responses in the near future.  All
information that may identify an individual observer will be deleted to
avoid possible embarrassment - so feel free to describe your eye
problems (if any) via email to fraserf@dove.net.au.  Or brag about your
visual excellence...!

A few of you commented about my use of the term "poor eyesight" in the
original question.  Therefore the following questionaire has been
prepared:

-----------------------------------------------------------------
(1) Do you wear spectacles/contact lenses?
        (a)  Never          <- go to question 5
        (b)  For reading
        (c)  Always, except when asleep or in the shower!
        (d)  Only at Fancy Dress Parties

(2) If you wear spectacles/contact lenses, do you remove them when
    looking through the eyepiece?

(3) Are you long-sighted or short-sighted?  What dioptre(s)?

(4) Are you astigmatic in either or both eyes?

(5) How would you describe your naked-eye vision _without_
    spectacles/contacts?
        (a) I can see Proxima Cen
        (b) I can split Beta Ori
        (c) I can see more than 6 stars in the Pleiades
        (d) I can split Theta & Iota Ori
        (e) I can see the 7 brightest stars in Orion
        (f) I can see Alpha Ori at maximum
        (g) I can't see Orion (even during power failures)
        (h) My Guide Dog helps me to find my telescope

(6) Do you have any non-refractive eye problems?  Eg: glaucoma,
    cataracts, colour blindness, retinal damage.

-----------------------------------------------------------------------

For the record, my latest eye test results were:
left eye    : -4.75 dioptre
right eye   : -9.25 dioptre (mean value) plus triaxial astigmatism
No other problems, but "abnormal sensitivity to faint light" noted.
