Key Words
Key words used in eyeglasses prescription
Here's a quick overview of common terms used in eyeglass and contact lens prescriptions:
OD: Oculus Dexter is Latin for right eye.
OS: Oculus Sinister is Latin for left eye.
Sphere, SPH, or S: Sphere is associated with curvature of the eye lens. A + ve number indicates you are farsighted and a - ve indicates you are nearsighted.
Cylinder, CYL, or C: Cylinder is associated with irregular curvatures in the cornea and eye shape that cause focusing distortions associated with astigmatism. Cylindrical (toric) lenses have specific curvatures and orientation that compensate for eye surface irregularities.
Axis: Axis is related to how the lens will be oriented in degrees to help determine whether, in focusing, images will be elongated or constricted to help offset vision defects associated with astigmatism.
Add: is used for people with both farsighted and nearsightedness, this number will indicate the nearsighted power in there vision. We have Bifocals and Progressives available for you.
PD/ Pupillary Distance: is the distance between the center of two pupils (center black dots between the eyeball).

Ways of Writing Prescriptions
Please Note: Prescriptions can change, so please do not enter prescriptions older than 1 year.
 
Doctors have different ways of writing Prescriptions. The following samples show 3 ways of writing the same prescription.
Rx SPH CYL AXIS ADD
RIGHT(OD) -2.25 -1.75 95 +1.5
LEFT (OS) -1.50 -1.50 90 +1.5
Fig. A
Rx SPH CYL AXIS ADD
RIGHT(OD) -225 -175 95 +15
LEFT (OS) -150 -150 90 +15
Fig. B
  Rx SPH CYL AXIS
DIST. RIGHT(OD) -2.25 -1.75 95
LEFT (OS) -1.50 -1.50 90
  Rx SPH CYL AXIS
NEAR. RIGHT(OD) -.25 +1.00 95
LEFT (OS) -1.50 -1.50 90
Fig. C
1) Pay special Attention to the Signs. A (+) Plus power is NOT the same as a (-) minus power.
2) Distance may be abbreviated as D.V and Near may be Abbreviated as N.V
3) Decimal Points may be left out as in figure B Prescription strength typically do not go higher than 15 or so. If your prescription shows 20 or 200 for any value, 95% of the time this means 2.00
4) If there is a blank space in your prescription, then leave that value as blank in the online prescription form. For example : if your Rx has only SPH powers, then fill in the appropriate value in the form and leave all the rest blank.
5) Distance power and near power may be given separately and no ADD power specified, as in FIG. C. Enter the Near vision power if you want near vision glasses and enter the Distance power for distance vision glasses.
6) If there is only one Add Power, It is understood that it is for both eyes
7) Some doctors might use a blank sheet of paper. Please remember that the first row is for Right eye and the second for the left eye. The first number in the row will be sphere, second is cylinder, third axis and fourth add.
PD
Pupilary Distance
The infamous PD
PD or Pupilary Distance is usually given on the prescription from your eyecare professional.
 
More and more doctors and stores will refuse to give you your PD to stop you from ordering glasses from a discount store (like LensesRX) and force you to buy from them at full retail price. Please be aware that this is illegal in most states and you can demand your PD at any time.
 
However, if you don't want to deal with the whole process you can simply take a ruler and measure the PD yourself, more instructions and pictures below.
PD is important for the placement of lenses inside your frames. To measure your PD, have a friend take a millimeter scale and measure the distance between your pupils (black dots in the center of your eye).
Place the ruler flat on your fore head, and line the zero with the pupil of your left eye, Take the reading where the pupil coincides with the right eye.
P.D of adults is generally between 55 to 65.
P.D of children is generally 44 to 54.
If your doctor supplies you with a P.D which has two numbers, then the first number is the Distance vision P.D and the second number is the Near vision P.D. For example: 63/60 .Enter the first PD if ordering Distance vision glasses and the second PD if ordering near vision.
Lens
Eyeglasses Lens
Single Vision: Prescription using only the SPH and sometimes the CYL and AXIS fields.

BiFocal: Prescription using the SPH and sometimes the CYL and AXIS fields, as well as the ADD fields. The produced lens has a little window for reading while the majority of the lens is for distance.

Trifocal: Trifocal lenses are made in similar styles to bifocals, but with an additional segment for intermediate vision above the reading section.

Progressive: These are bifocal lenses that progress from distance to reading using the intermediate space. These are also called the no-line (no window) bifocal due to its smooth transition from one to the next.

Standard Lenses: These are the most common CR-39 lenses used in just about every optical field.

Polycarbonate: These lenses are thinner and lighter than Standard lenses. It is generally very hard to break these lenses because of their durability.

Hi-index: The higher the index the thinner the lens is going to be. The higher the prescription the thicker the lens is going to be. If you want to buy a nice sleek frame but have a high prescription your Standard lens will be very thick and will look unappealing.
