Glass: Glass offers the
best optical clarity, meaning that there is virtually no distortion
in glass lenses. This is why it is the material of choice in
manufacturers such as Ray-Ban, Revo, Vuarnet, and Serengeti.
However, glass is the least impact resistant of all of the material,
and may shatter upon impact. Shattering means that the lens
will split into small pieces which can easily enter the eye and
cause permanent eye injuries or even blindness. Therefore,
glass is not recommended for any active sports where a fall or a hit
by a ball can shatter the lens. It is also the heaviest of all
the materials which may limit the length of time these lenses can be
worn. However, glass is the most scratch resistant of all
materials.
Plastic: CR-39 refers to the
type of plastic that is used to make prescription lenses. This
is optical plastic and provides very little distortion (more than
glass but less than polycarbonate). It is more lightweight and
thinner than glass making it comfortable to wear. It is more
impact resistant than glass, but may still break and shatter upon
impact. Therefore, it is not recommended for active sports.
It is more scratch resistant than polycarbonate, but will scratch if
not properly taken care of.
Polycarbonate:
Polycarbonate is an impact resistant material. Most good
polycarbonate can be shot at with a .38 caliber bullet and not
shatter. It is becoming used more and more today especially
for sports eyewear and sunglasses. Although polycarbonate is
impact resistant, it should not be consider breakproof or
shatterproof. However, polycarbonate is the strongest material
available and will have the tendency to break in large pieces versus
small pieces which are not as dangerous. Polycarbonate is the
thinnest and lightest of all materials. However, the lens also
has the most distortion of any lens, especially in wrap frames
unless the lens is decentered. However, only those very
sensitive to distortions will really notice it. Although tough, the
material is actually softer meaning it is more susceptible to
scratches. However, most polycarbonate lenses have scratch
resistant coatings built in to help prevent scratching.
Trivex(Phoenix):
Phoenix originated in the defense industry. It is as safe as
polycarbonate but offers better optical clarity (same as CR-39 plastic).
They are also more scratch resistant than standard polycarbonate and is more
resistant to chemicals. Trivex meets FDA and ANSI Z87.1 impact safety
standards at 1.3mm. It is the lightest lens available. 100% UV
protection is also standard and does not need to be added.

Eyesize is a term we use in the optical industry to measure frames. The
first number in the eyesize refers to the distance in millimeters across
(horizontally) one lens. The second number in the eyesize refers to the
distance between the two lenses or bridge size (measured in millimeters).
This information can help assist you in sizing a frame for your face. To
better understand the frame size, double the first number and add the second.
This will give you the distance across the full front of the frame. For
example, an eyesize of 51/16 means that the frame measures 118 mm across (51 x 2
+ 16 = 118). You can then put the ruler up on your face to see how big the frame
will be on you. If you only have inches on your ruler, 25mm equals 1 inch.
So, in our example, this frame would measure 4.72 inches (118 divided by 25).
Or, if you wear glasses, you can easily compare this measurement to your
glasses. Look on the bridge of your frame or on the temples. You
should see a similar number separated by a box. This is your frame's
measurements. You can see how it compares to the frame you are looking at
on our website. Note: If you are wearing a metal frame, most likely your
frame has a small eyesize and doesn't go to the end of your face. If this is the
case, the first method is a better way of calculating eyesize. You want
the frames to be larger than your regular glasses for more coverage and better
peripheral vision.
Some brands may also give other measurements. The "B" is the height of
the lens top to bottom in millimeters. The "ED" is the distance
diagonally across the lens in mm. "A" is the distance across the lens
(same as mentioned above) The DBL is the bridge size (same as referred
to above). The TPL is the length of the temple or earpiece.
See UV information page here. All
sunglasses A Sight for Sport Eyes carries have 100% UVABC protection. All
products with Polycarbonate lenses (ie. ski goggles, sports goggles, swim
goggles, etc. also have 100% UVABC protection. Refer to brand pages for
any exceptions, but there are only a few things we offer that don't have UV
protection (Barracuda CR-39 lenses). Also, 100% UV can be added to all
custom prescription lenses for an additional charge (included on polycarbonate
lenses)
See return information here.
Unfortunately, we only have one retail location in Portland, Oregon.
However, we do offer a buy, try and return option. You simply order all
the styles you would like to try (limit 3). You will be charged, but your
order should come to over $50 so there will be no shipping charge. Try on
the items, and return the ones that you don't like for a full refund. The
only thing you have to lose is the small shipping charges to return the items to
us, which is equivalent to what you would pay to ship the glasses to you if you
knew exactly what you wanted. We don't discourage this policy as we know
sunglasses are a difficult item to purchase without trying them on. This
is especially true for prescriptions. Since prescriptions are not
returnable, it is best to try them on first, then send them back to have the
prescription lenses made.

certificate number in the comments section of the order form. We will
verify the certificate, and then ship your order.
If you order total is greater than the amount of your GiveAnything.com Gift
Certificate, select a payment method for the balance (i.e. credit card, check,
money order, etc.) Then place the certificate number in the comments
section. We will verify the certificate and then apply the certificate to your
order total. You will be charged only for the difference between the order total
and the gift certificate.

This is usually not written
on your prescription, but is a measurement taken by the optician filling the
prescription. However, since we do not have you sitting in front of us to take
the measurement, we need you to provide this information to us. A PD
refers to your pupilary distance, or the distance between your pupils. Do not
attempt to take this measurement yourself as it is taken with your
eyes looking in different directions. But you can have another
person measure this for you. It is the distance from the center of one pupil to
to center of the other pupil in millimeters. A PD ensures that the
center of the lenses line up with the center of your pupils where
you will get the best vision. If you don't provide one, we will use a
standard unless we feel that your prescription is too high and too much
distortion will be induced if we use a standard one.
PD is not necessary for step diopter products. PD is usually written
like this: PD=60. Or it could be split per eye like 30/30.
Frame is an 8-base wrap. It is available with a prescription up to a -4.00
with a $20 base curve charge. Because of the curvature, vision may be
subject to distortion.
Frame is
available with a prescription lens built directly into the frame with no special
charges.
Available with a prescription insert or adapter. This is a frame that is
the carrier of the prescription and then snaps in behind the front lenses of the
frame. This creates a double frame effect but is advantageous for those
who want interchangeable lenses. This allows you to essentially have
several pairs of sunglasses with only one prescription lens.
There are many popular brands such as Oakley, Costa del Mar, Ray-Ban and Revo.
We have tried very hard to carry this product, however, these companies will not
let us carry their brands. If you would like to see us carry these brands
in the future, please contact the manufacturer directly (see below) and request
that Sporteyes should be allowed to sell their product. We are not sure
why they will not allow us to sell their product, as one would think they would
want the money. However, some of these companies are "snobby" and the
vendor must have the right "look" to sell the product. Other companies do
not want their product sold on-line (such as Nike and Adidas) and hold us under
contract not to do so.
Here is where you can contact the manufacturers directly to request that
Sporteyes should be a vendor:
Oakley: info@oakley.com
Ray-Ban and Revo:

Yes. These are commonly referred to as photochromic or photochromatic lenses.
In prescription glass lenses, we use the PhotoGray or PhotoBrown lenses. In all
other lens materials, we use Transitions lenses (most
current generation--we do not use past generations of lenses--be warned that
some places may charge less because they are using previous technology. We
only use the most current technology for all our lenses). These can be ordered from
our Prescription Information page to
almost any style. Many of the manufacturers are offering light changing
lenses as well in non-prescription. Rudy Project has the ImpactX lens. Wiley-X
has the Light Adjusting (LA) lenses. Panoptx has Day & Night lenses.
You can also go with an interchangeable lens style. This allows you to manually
change the lenses out of the frame for various light conditions. Many brands
have this option.
Back to Top
Yes and no. We don't accept insurance currently in lieu of payment but
can fill out any paperwork you need so you can be reimbursed by your insurance
company. Because we only have opticians here and no doctors, most
insurance companies will not allow us to become a provider. If you have a
plan that will accept opticians, let us know and we will see if we can easily
become a provider for you. We also do accept Care
Credit which is a medical financing program to help break the cost up into
reasonable payments.
Occasionally we do have coupons and specials. We post all the general
promotions on our home page. For limited time offers, we post these on our
Twitter account or via our newsletter. You can follow us on Twitter for
the weekly deals, or subscribe to our newsletter for monthly deals. Create
