Frequently Asked Questions
Q: Can I return my prescription order?
A: You can return your prescription order only if the product is defective, otherwise all prescription
orders are final. Wiley X strives to provide exceptional customer service. We are committed to meeting our customers needs.
Q: What is Pupil Distance?
A: Pupillary Distance (Pupil or PD for short) is the distance in millimeters between the
center of the pupil in the right eye and the center of the pupil in the left eye. A mono
PD is necessary for all progressive lenses. It is measured from the nose to the center of
each pupil. This measurement should be obtained from your eye care professional.
Q: What is the ADD Power (on Bi-Focal and Progressive orders)?
A: The ADD Power is the total power needed over the distance prescription which allows
you to see clearly up close. A Bi-Focal, or FT-28, lens provides vision correction for
distance and reading only. A progressive PAL (Progressive Additive Lens) provides vision
correction for distance, intermediate, and reading.
Q: What is the Seg Height (on Bi-Focal and Progressive Orders)?
A: The Segment Height (Seg. Ht. for short) is a measurement taken by your eye care professional
to determine the vertical placement of your pupil within the frame. This measurement is needed for Bifocal
and Progressive lens orders.
Q: Can I get a Bi-Focal prescription for my Wiley X sunglasses?
A:Yes. Wiley X offers Single Vision, Bifocal (Flat Top) and Progressive prescription lenses.
Q: Which Wiley X models accept prescription lenses?
A: Wiley X prescription models can accommodate single, bi-focal and progressive prescription lenses. To identify prescription models on our website first select a product that interests you. Once you select it you will be taken to
our product details page. If the product can accommodate a prescription lens you will see a Prescription link under the product image. Note: Non-military prescriptions sunglasses cannot be ordered
online but must be ordered through a Wiley X dealer.
Q: What type of prescription lenses does Wiley X offer?
A: Wiley X offers conventional surfacing technology or industry leading digital surfacing
technology prescription lenses. Conventional lenses can accommodate single vision, bifocal and
progressive prescriptions. Digital lenses can accommodate single vision, sport and progressive prescriptions.
Q: Am I limited in the colors and styles of lenses that I can order with a prescription?
A: All Wiley X prescription lenses are made from polycarbonate material to exceed ANSI safety standards.
Prescription lenses can be ordered in a variety of colors and styles such as clear, tinted, mirrored,
Light Adjusting, and Polarized. We can also add anti-reflective and anti-fog coatings.
Q: Can Wiley X accommodate a complicated prescription?
A: Yes. Wiley X Digital Surfacing Technology allows us to accommodate a wider range of prescriptions
with a higher degree of accuracy. If Conventional Surfacing Technology cannot accommodate your prescription,
Digital likely can. Please contact one of our dealers to help you determine if one or both surfacing types can accommodate your prescription.
Q: Will my Wiley X sunglasses still be interchangeable with prescription lenses?
A: Only the SG-1, SG-1 V-Cut and Guard are interchangeable with prescription lenses. Please note:
Most Wiley X interchangeable models come with two sets of lenses. You will NOT receive a second set
of lenses with your prescription order.
