How to add prescription lenses to your frame?

STEP 1

Obtain a copy of your eyeglass prescription from your eye doctor. Be sure that the prescription includes the pupillary distance (PD) measurement. This will ensure that the center of the lenses will be in line with your pupils.

Select Lens Type

We offer 4 types of lenses to choose from. See the table below to learn about each type.

Single Vision	Bifocal	Trifocal	Progressive
Lenses correct one field of vision - same focal power throughout top to bottom.	Bifocal lenses have two parts: the upper part normally used for distance-vision and the lower part used for near-vision tasks.	Trifocal lenses have three different focus areas: the top for distance-vision, the center for intermediate-vision, and the bottom for near-vision.	No-Line Bifocal which offers three different focus areas: top for distance vision, the center for intermediate vision and the bottom for near vision.
Used to correct nearsightedness (myopia) or farsightedness (hyperiopia).	Bifocals are usually prescribed for people with presbyopia who need a different prescription to see near objects. Great for reading.	Trifocal eyeglass lenses have an additional lens segment immediately above the bifocal's near segment for seeing objects in the intermediate zone of vision -- approximately 18 to 24 inches away. Great for computer use and for seeing speedometer.	Lenses allow the eye to transition focus smoothly between one distance zone to another without visual jumps.
	A visible line called divides the different parts of the lens.	A visible line divides the different parts of the lens.	More flattering than multifocals because they do not have visible lines.

Select Lens Material

Next, select from one of three lens materials including: Plastic (CR 39) is a lightweight plastic lens material that is much lighter and less breakable than glass lenses. They may be made in just about any prescription, though many people with higher prescriptions prefer to use Hi-Index Lenses. They are also great fro prescription sunglasses due to their tintability factor. Polycarbonate lenses are the most impact resistant material (shatter resistant) and most suitable for children or active adults. They provide the best eye protection of any lens and include 100% UV protection. They are thinner and lighter than CR-39 plastic lenses. The suggested prescription range is plano (0, no Rx) to +/-8.00 sphere (most suitable for +/-2.00 sphere and higher).They are very difficult to tint and are not recommended for people who want to custom dark sunglass lenses. Hi-Index lenses are good for higher prescriptions because they do not look thick, do not magnify or minify your eyes when seen by others, and are lighter. The suggested prescriptions range is +/4.00 to +/-8.00 sphere. Good for everyday use.

Select Lens Material

Depending on your selection of lens material in the previous step, you will have the option to select from among the top lens brands and whether you would like regular lenses (transparent), transition or polarized lenses. Read more about the different lenses below: Transition lenses change from light to dark in response to the UV levels of light. These lenses are very convenient, replacing sunglasses and allowing you to only need one pair of glasses instead of two. Polarized lenses are tinted lenses that block vertical light from hitting your eye and causing eye strain. Hunters, boaters and fishermen, golfers, and drivers are the most common users of polarized lenses. Any surface can create glare in sunlight, including water, sand, snow, windows, vehicles, and buildings. Polarized lenses ease eye stress and fatigue in the sun, and lenses are available in several color and density options.

Select Lens Coating

Lens coating is a great way to protect your lenses. Choose from one of these options: Scratch resistant lenses are coated front and back with a clear coating that have a much harder surface that is more resistant to scratching. Recommended especially for kids' lenses. UV protection is a coating that protects the eyes from ultraviolet sun rays. Using a tinted lens without UV protection can be extremely dangerous. It causes the pupils to dilate, admitting more UV light to the intraocular lens, which can cause premature cataracts and/or permanent damage to your eyes. Anti-reflective (AR) is a coating that reduces both internal and external reflections on the lenses, creating a nicer cosmetic appearance and reduction in glare; ideal for computer use and night driving. Mirror coatings are generally applied over sunglass-dark lenses and are purely cosmetic: the wearer perceives no difference in vision regardless of what color the coating is. It helps deflect reflected light.

Select Lens Tint

Looking for a tint on your lenses? Choose from: Grey tints provide good protection from glare and keeps distortion of colors to a minimum. Grey is sometimes referred to as a "tru-color" tint. It is available in a wide range of densities and is an excellent choice for general use and driving. Grey is the most popular sunglass tint. Brown tints work well in variable light conditions and provide good contrast because they filter some blue light, although not as strongly as a yellow tint. Brown lenses are good general purpose lenses and work especially well for sports where judging distance is important like tennis and golf.

How to read your prescription (Rx)?

Whether you choose single vision, bifocals or transition lenses, completing your order is as easy as reading your prescription and entering it in our electronic easy-to-use form.

Your prescription provides us with your doctor's recommendation for clear and comfortable vision. When ordering prescription eyeglasses online, be sure your eye doctor writes your Pupillary Distance (PD) measurement on your prescription. This ensures the optical center of your lenses will be exactly in front of your pupils.

Please review your information with our 4 samples below:

Sample 1

Prescription Glossary:


• RX - Your Prescription
• O.D. / Oculus Dexter- Right Eye
• O.S. / Oculus Sinister - Left Eye
• O.U. - Both Eyes
• SPH / Spherical - Corrective power for distance or reading; near (-) or far (+) sightedness
• CYL / Cylinder - Corrective power for astigmatism (if applicable)
• Axis - Corrective axis for astigmatism; it is an angle between 0 and 180 degrees (if applicable)
• ADD / Add Power - Magnification for reading (mainly applicable for the bottom half of Bifocal/Trifocal/Progressive Lenses)
• PD - Pupillary Distance or the distance between the center of each pupil (in mm)
• PL / Plo / Plano - Placeholder for the number zero; you may leave the fields blank or enter 0.00
• Prism - When the two eyes are not properly aligned and looking directly at the same thing, prism can be ground in to the lenses in order to re-align them (if applicable)
• Base - The base is to the prism what the axis is to the cylinder (if applicable)
• DV - An abbreviation for Distance-Vision
• NV / NVO - Near-Vision or Near-Vision-Only; your optician is recommending reading-only glasses
• -100 = - 1.00
• +225 = +2.25

Please Note:


1. Astigmatism correction ("CYL / Cylinder"). Some doctors write their prescriptions in plus (+) cylinder and some in minus (-) cylinder. They are not the same. Take special note of this when entering your prescription later. If you don't see anything there, leave it blank.
2. Your doctor may use a blank Rx pad, not a pre-made Rx pad for eyeglasses only. If this is the case, you can draw imaginary grid-lines to separate the numbers. It will separate the different values more easily for you. The top power is always the right eye & the bottom power is always the left.
3. If you don't see numbers in some of the boxes (if there is no CYL or AXIS or ADD), leave those values blank when ordering. If you only see one number for each eye, it's the "SPH / Sphere" power; leave all the other fields blank.
4. It is common for the doctor to sometimes leave out the decimal points. If you see a number like -100 or +225, it is understood that your doctor means -1.00 or +2.25., respectively. Also, an axis of 5 or 05 is the same as 005; 70 is the same as 070. It's like using abbreviations or writing in short-hand.
5. If you have no astigmatism in one or both eyes, your doctor may just write the sphere power alone, or may use placeholders like sph ("sphere") or D.S. ("diopters sphere") instead.
6. If you have a prescription for bifocals and you only see one ADD power, that means that you have the same ADD for both eyes. If you don't see an ADD power, leave it blank.

If you need help in understanding any part of your prescription, please contact us to ensure everything is entered correctly as prescribed. We are here to assist you and we want your glasses to be made exactly to your doctor's specifications.

What is Pupillary Distance (PD) and how to measure it?

This measurement is used to accurately center the lenses in the frame that you have selected. Pupillary Distance (PD) is the distance from the center of the pupil (black circle) in one eye to the center of the pupil in the other eye. It is called Binocular PD.

In cases where the pupils are not equidistant from the nose, a monocular PD is required. Monocular PD is measured from the centerline of the nose to each pupil. In such a case you will have different values for the right eye (Mono R) and the left eye (Mono L). For example, 33/29 are the measurements from the center of the nose to either eye. Your PD is the sum of the two, 33 + 29 = 62 (Mono R + Mono L = PD).

You can measure this yourself in a mirror or have a friend do it for you:


1. Place ruler (in mm) on the bridge of your nose just under the pupils of your eyes
2. Measure the distance between the centers of your pupils with your eyes looking straight into the distance, and not at the person measuring you

Note:

Typical adult's Pupillary Distance measurements (PDs) are from 54 to 70 mm.
Typical children's Pupillary Distance measurements (PDs) are from 41 to 58 mm.

Sometimes a prescription has two numbers, written such as PD 62/59 usually written on a bifocal prescription. This means that 62 is your distance-vision PD, and the one to be entered on our forms. And 59 is the reading or near-vision PD, the one to be used only if you are ordering a plain reading glass only. Reading or near-vision PD is usually shorter than distance-vision PD by 2 to 5 mm.

It is critical for you to either get the PD from your doctor or to measure your PD at home so that your prescription is accurate. Without an accurate PD, you may find that your glasses may cause blurring or headaches.
