prescriptions questions for Wiley X prescription Sunglases

Postby Admin on Thu Aug 12, 2004 4:19 pm

Some questions:
1. For Wiley sunglasses/goggles, the general statement is that they won't
accept (+) prescriptions.
1a. Is it correct that when you refer to (+) prescriptions you are
referring to diopter spheres i.e. corrections for "longsighted-ness" (characterized by inability to focus on close objects).
1b. But under the WileyX SG-1 goggles entry you have that it can accept -4 to +3
sphere prescriptions. Which others of the Wiley sunglasses/goggles can
accept (+) prescriptions? Is it possible, rather than have a general
statement, to say in the descriptions of each frame whether it can accept
(+) prescriptions? e.g. "Wiley-X JP-1 sunglasses cannot accept (+)
prescriptions i.e. Wiley-X JP-1 sunglasses cannot accept (+) diopter
sphere prescriptions".
1c. Can you explain why (+) prescriptions cannot be filled? To me, these
lenses are thinner at the edge (i.e. at the frame) than in the center of
the lense. So they should be able to fit into the frame, whereas (-)
prescriptions, which have lenses thicker at the edge (i.e. thicker "glass"
at the frame) than in the center of the lense, might not be able to fit
into the frame, since the lense might be too wide (from inside surface to
outside surface) to fit into the frame housing?
2. One or two of the frames have specifications for width, height,
diagonal, distance between lenses.
2a. Will you be adding these numbers for all the frames (in particular
prescription frames)?
2b. Some of them have e.g. (see
http://www.opticsplanet.com/wiley-x-sun ... rized.html ) A.
Nosebridge Measurement to temple 65mm, B. Brow to Cheek Measurement 36mm, ED. Nosebridge to deepest part of lense diagonal measurement 60mm. But:
2bi. For the ED measurement the diagram shows a line that does not connect to the nosebridge.
2bii. The other end of the ED measurement line does not go to the deepest or widest part of the frame, so it is difficult to know what point on the frame is being referred to by the phrase "deepest part of lense" in the
definition of ED. If the phrase had been "maximum diagonal" this would seem to me to better match the line shown (although in this example, it would seem the maximum diagonal would be 65mm, the measurement for A. Nosebridge Measurement to temple (65mm), since 65mm is longer than 60mm, the measurement for ED. Nosebridge to deepest part of lense diagonal measurement (60mm)).
2biii. For reasonably square frames e.g. the Wiley-X 50, then by
Pythagoras, the measurement across the diagonal should be more than 65mm. The diagram shown matches the shape of say the Wiley-X 100, but not the shape of the Wiley-X 50, and so it is hard in that case to know just what is being measured, which makes it hard to want to order them, given that the prescription versions are non-returnable.

May I say that your site is the best of the sites for prescription sunglasses that I could find, and it seems to be the only site that is a serious attempt to provide full information for actual products. A lot of other sites mention that you can buy prescription sunglasses from them, but give practically no useful information to use as a basis for a purchase
decision.

Thanks

Lawrence,

Thank you for your interest in www.OpticsPlanet.com. All of the prescription frames can take a positive script, it just depends on the strength, and the pupil distance (PD). Positive prescriptions are harder to do because of the thickness of the lens at the nasal of the frame, they tend to pop out easier. If you let us know exactly what your prescription is, I can check the possibility of putting that in a specific frame for you.

We have not added all the measurements for the frames to our prescription pages yet. However, if you check on the pages for each non-prescription frame, you will find measurements listed, http://www.opticsplanet.com/wileyx-sunglasses-sg-1.html
We will be getting that fixed shortly.

Wiley X SG-1 Frame Specifications:


A (Nosebridge Measurement to Temple): 64mm

B (Brow to Cheek Measurement): 37mm

DBL (Nosebridge Only Measurement): 23mm

ED (Nosebridge to Deepest Part of Lens Diagonal Measurement): 65mm


Sunglasses are always a matter of preference. What fits me, does not generally fit everyone else. That's why, we now have a page listed here, http://www.opticsplanet.com/prescriptio ... trial.html, with some non-prescription frames available, that we would loan you, so you can see if they fit properly.

I hope this has been helpful. Please let us know if there is anything else we can help you with. Thank you.

Best Regards,
