Technical Prescription Details
How do I read my prescription? What do all the abbreviations
and numbers mean?
The key to reading your eyeglasses prescription, whether you
have nearsightedness, farsightedness, astigmatism, or anything
else, is knowing what OD and OS stand for.
Sometimes appearing as O.D. and O.S. (oculus dexter and oculus
sinister), which are abbreviations in Latin for right eye (OD)
and left eye (OS). Some doctors may use O.U. which means both
eyes, or RE and LE for right eye and left eye, respectively.
There are other abbreviations in your eye prescription.Here is
what each of them means:
Sphere (SPH): Measured in diopters, the number under this header
refers to the lens power necessary for each eye. A minus (-) is
used to correct nearsightedness. A plus (+) sign next to the
number refers to farsightedness correction.
Cylinder (CYL): The lens power (also diopters) used to correct
astigmatism. If you have no astigmatism or very slight one,
nothing will appear under this column. Just like with Sphere,
minus is used to indicate lens power for nearsighted
astigmatism, plus is for farsighted astigmatism.
Axis (Ax): Like Cylinder, this only applies to astigmatism
prescriptions. The numbers under this column refer to angle
degrees (1 to 180) and not diopters. If your prescription
includes Cylinder lens power, it must include Axis as well.
Add: Only used for multifocal (progressive/bifocal) lenses. It
refers to the added magnifying power applied to the bottom of
the lens in multifocal lenses. PAL is used in some cases by eye
doctors when the addition for progressive lenses is different
compared to bifocals.
Prism: Prism is used to correct double vision or vision
displacement. The value on the prescription refers to the number
of diopters applied to compensate for the image alignment
Segment Height: SH or seg is the vertical measurement in
millimeters from bottom of the lens to the beginning of the
progressive addition on a progressive lens, or the top line of a
lined bifocal. Segment height does not apply to single vision.
What is pupillary distance (PD)?
The distance between your pupils. This measurement is used for
an accurate determination where you look through the lens of
glasses or sunglasses.
How can I measure pupillary distance (PD)?
Learn how to measure your PD if it is not included in your prescription.
Measure PD with a Ruler and a mirror
Stand 8 in away from a mirror.
- Hold a ruler against your brow line.
- Close your right eye
Align the ruler’s 0 mm with the center of your left pupil.
- Look straight ahead.
- Close your left eye and open your right eye.
The mm line that lines up to the center of your right pupil is
- You now have a single PD measurement.
What is the difference between standard and high-index
Our standard lenses are made with polycarbonate, an extremely
tough transparent plastic with impact resistance. High index
lenses are thinner, more powerful lenses. They're lightweight
and stylish, but are mostly reserved for those with higher
vision correction needs. While most prescriptions are compatible
with more than one specific index, it's up to you to decide
which one fits your personal needs
Do you offer prescriptions with prism correction?
Currently we do not have prism correction service available.
Are there any limits on the types of prescriptions you can
We currently offer prescription lenses in single vision and
progressive. Most of our prescription frame assortment will
support total power ranges from -9 to +3. To calculate your
total power range, simply add the sphere and cylinder numbers
together. You will have to repeat this for both eyes to ensure
both prescriptions can be fulfilled. For example, if your sphere
is -2.75 and your cylinder is -.75 for your left eye, your total
left eye power is -3.5. -2.75 + -.75 = -3.5. LEFT (OS) Left
Sphere: -8 to 3 (OS) Left Cylinder: -3 to 3 (OS) Left PD: 27 to
37 (OS) Left Axis: 0 to 180 RIGHT (OD) Right Sphere: -8 to 3
(OD) Right Cylinder: -3 to 3 (OD) Right PD: 27 to 37 (OD) Right
Axis: 0 to 180
What is a bifocal or progressive lens? And do you offer
bifocals or progressive lenses?
Bifocals contain two lens powers. Progressive multifocal lenses
gradually change in power from the top half of the lens to the
bottom, and thus contain many lens powers. Currently we do not
have bifocals. Most of our prescription glasses offer
What are blue-light blocking lenses? And do you offer
prescriptions with blue-light lenses?
A filter in the lens that blocks and filters out blue light from
getting through. Highly recommended when looking at screens on
your computer, phones and other electronic devices. It reduces
the exposure to blue light waves that tire your eyes, affect
sleep and overall well-being.
We do offer a standard blue light lens. Our blue-light lenses
block high-energy visible blue light emitted from digital
screens on computers, televisions and mobile devices. Unlike
most blue-light lenses, ours do not have a yellow tint that
results from a coating applied to the glasses. Our blue-light
technology is actually built into the polycarbonate lens to give
you durable protection and a crystal-clear view.
Do your blue-light lenses have a yellow tint?
Although many blue-light lenses have yellow-tinted lenses to
filter out HEV blue light, our blue-light lenses do not have a
Why is it important that the frames fit you properly?
Every human head is unique, each face has different measurements
and no other eyes on earth are exactly like yours. Since
eyeglass frames fit certain face shapes differently, it is
important to observe how a frame rests on your unique facial
features. For example, if the bridge area does not fit properly
on your nose then the glasses will slide down, affecting not
only how they look and feel but also how you see. Also, if
glasses are too narrow and tight, then they may put pressure on
your face while restricting your peripheral vision. Wearing
lenses with incorrect alignment specifications will commonly
cause issues such as visual discomfort, blurriness, eye strain,
“pulling sensation” and headaches.
How can I adjust the nose pads?
Grasp glasses by the bridge between thumb and forefinger. Do
not hold by the frame or lenses.
After you have done step 1, gently pull apart the nose pads.
Try not to do this too often, or you will wear down the metal.
Its important that you find the sweet spot so that the frames
will sit comfortably on the bridge of your nose.
How can I adjust the arms/temples of my new frames?
If you wear metal frames: Simply widen the plastic nose pads
using your thumbs until the frames fit comfortably.
If you wear plastic frames:
First soak the arms of your glasses in hot/warm water for
30-60 seconds. Alternatively, you can use a blow dryer on a
warm setting to make the arms more pliable.
Gently apply an upward outward pressure at the end of the arms
to achieve a more relaxed fit.
If the frame slides down your face too much you can bend the
earpiece/temple closer to a 90-degree angle to tighten the
