Yes, you can purchase frames only without lenses. If you decide you would like to purchase lenses later, you can send your frames back to us and we will add prescription lenses to them for you.
You may be able to find your frame size numbers printed on the inside of your current eyeglass or sunglasses frames.
Every pair of glasses is a little different, so the size information may not always be located in the same place.
size on your current frames:
Look on the inside of your current frames. You will find the size information stamped either on the temple, like this example:
Or on the bridge, like on this metal example:
or like on this plastic nose bridge:
On some models, you may also find the size stamped on the ear piece.
What to look for:
There can be quite a few different kinds of numbers and markings inside your frame, and not all of them are relevant to the size.
The eye size and bridge size are often located next to one another, sometimes separated by a square box icon. The temple size may immediately follow those two sets of numbers, or have some other info in between.
You are looking for (2) two-digit numbers and one three-digit number. Here’s how to identify them:
Eye Size: a two-digit number in the 40 – 62 range
Bridge Size: a two-digit number in the 14 – 24 range
Temple size: a three-digit number in the 120 – 150 range
The eye size is the most important number to pay attention to. Depending on the style of frames you choose, you can go up or down by one and still find a decent fit.
What you can ignore:
A set of capital letters and numbers grouped together is generally the model number or the frame color/style number(s). In the image above, “VPR 020” is the frame model number while “EAJ-101” is the color/style number.
Sunglasses tend to be larger than eyeglasses, so your sunglasses size will most likely be different than your eyeglasses size. With sunglasses, you have more freedom to choose within a wider range of sizes, since the fit does not need to be as precise.

The ideal material for your lenses depends on your prescription.
Plastic lenses are recommended for light prescriptions, ranging from no correction to +/-1.75.
Polycarbonate lenses are 30% thinner and lighter than plastic and recommended for people with prescriptions ranging from +/- 2.00 to +/-4.00. Polycarbonate is also recommended for children under 18 years of age and anyone who has an active lifestyle, due to its impact-resistance. Rimless and semi-rimless frames also work best with polycarbonate lenses.
Trivex lenses is a relatively new optical lens material. It has the ultraviolet blocking properties (380 nanometers and less) and shatter resistant properties of polycarbonate. However, Trivex lenses have a much higher abbe value (43-45) vs. polycarbonate (abbe value 30) making it much better in optical clarity with fewer chromatic aberrations. Trivex also has a slightly lower density so it is lighter than polycarbonate. In fact, Trivex is the lightest weight lens material available. Another advantage that Trivex has over polycarbonate is that it can be easily tinted. Trivex along with polycarbonate is great for rimless frames and those frames requiring drill mount screws through the lenses.
1.67 – 1.74 Hi-Index plastic lenses are 45% thinner than plastic lenses and help reduce the distortion of your eyes that people see when they look at you through your glasses. This lens material is recommended for people with prescriptions of +/- 2.00 and greater.
Glass lenses provide excellent optics, the most scratch resistant lens material and blocks UV light. However, glass lenses are heavy, thick and dangerous if broken and cannot be used in certain frame styles. Some glass is available with a refractive index as high as 1.8 and 1.9, it mostly used for strong prescriptions of +/- 9.00 and greater.
Standard features come without additional charge, premium features can be added to your lenses if you choose the relevant options.
There is no difference between anti -reflective (AR) and anti -glare coatings; they are the same thing. This coating helps minimize the reflections you see on both the inside and outside of your lenses.
First-time progressive lens wearers often need a little time to get used to them. Your eye and brain have to learn to adjust to the different corrective powers within the lenses. You may need a week or so to adjust. If you continue to have vision problems after that time, please contact your eye doctor to double check the prescription.
If your eye doctor is able to verify that the prescription is accurate, then it may just be a matter of adjusting your glasses so that your frames sit in the correct position on your face.
Mostly photochromic lenses will only change color when exposed to direct UV rays. The lenses may not get as dark on a cloudy day as a sunny day, nor will they darken in a car since most windshields have a UV filter built into the glass.
Some specialized photochromic lenses does make a “drivewear” feature that will change color in a car. If you would like to add it or any other special requirements to your glasses, please contact our customer service.
Bifocal lenses offers two different viewing zones: the top part of the lens is for distance (i.e. to help you see things far away) and the lower part for the lens is for reading (i.e. to help you see things up close). The viewing zones of bi-focal lenses are divided by a visible line.
Progressive lenses are essentially no-line as bi-focals. But instead of offering just two different viewing zones (near and far vision), progressive lenses offer many different focal points by seamlessly transitioning from distance vision to intermediate and near vision and everything in between. Progressive lenses provide much more natural vision and are typically recommended over bi-focal lenses.
Yes, wcolo.com will allow you to purchase prescription lenses only.
However, you must send us your eyeglass or sunglass frames before we can process your order because we will need to cut the prescription lenses to fit your exact frame. But it is also ok if you want just the original raw lenses only, then you will take the responsibility to assemble it with your frame.
Please contact our customer service for details.
Yes, wcolo.com can replace the prescription lenses in your current frame. However, you must send us your frames before we can process your order because we will need to cut the prescription lenses to fit your exact frame.
Yes. We can add lenses to frames from products that we currently carry on wcolo.com, or your own frames, whatever.
Usually it would be ok. But if we fear there is a chance your own frames could be broken in the assembling process, wcolo.com will call you to discuss it.
Yes. We can make lenses that include a prism. All prescription orders will be seriously verified before processing. If your written prescription has a prism, we will confirm with you before crafting your custom lenses.
Single-vision means that you are either near sighted or far sighted, but not both (as is the case with people who need bi-focal or progressive lenses). Single-vision is the term used to refer to corrective prescription lenses that do not have multiple viewing zones, like bi-focals and progressives do.
Pupillary distance (PD) is simply the distance (in millimeters) between the centers of your pupils. PD is important because it helps us figure out where the optical center of your lenses should be.
Ask your eye doctor to include your PD when s/he writes out your prescription. If your eye care professional cannot provide your PD, there are some simple ways you can measure it by yourself, please contact our customer service for details.
How to clean your eyewear:
Clean your glasses by using warm water and a mild dish soap.
Dry your glasses gently with a soft cotton towel or cleaning cloth for eyeglasses.
A soft toothbrush can be used to wash away any grime around the nose pads. Be careful not to accidently scuff the lens.
Avoid using rough materials such as facial tissue or paper towels to dry your glasses, as they may scratch your frame or lenses.
Avoid using any cleaners containing ammonia (such as Windex) or lotions (like some hand soaps), as these products could damage your lenses.
How to care for your eyewear:
Avoid leaving your glasses in a hot vehicle. High heat could damage the frame and lenses.
Avoid touching your lenses with your hands to prevent contact with dirt and oil particles that could scratch the surface.
When not using your glasses, keep them in a case to avoid scratches.
Before shipping your glasses to you, we will adjust them based on standard fit. If you require further adjustments, we encourage you to visit a local optical store. Most brick-and-mortar eyewear retailers will adjust your glasses free of charge, as courtesy.
We do not recommend adjusting your glasses yourself, as excessive force or bending can break the frames or lenses.
