What information do I need to order glasses?
Glassesonweb.com can install single vision prescription lenses for you. We do NOT install multifocal lenses (progressive, bifocal, or trifocal) into your eye glasses.
You can order eyeglass frames without lenses, and then take the frames to a local optical professional to have the lenses installed. To order
prescription lenses for your eyewear, you will need to visit an eye doctor (ophthalmologist or optometrist) and have an eye exam. During your eye exam, ask them to measure you pupillary distance (“PD”),
and write your PD down on your prescription. Once you have your prescription and PD, you can order prescription lenses. To order, click on the lenses link at the top of any page of our website.
This will take you to the lens wizard, which will guide you through the process of uploading your information to the website and selecting a lens.
Can I send in my glasses to have new lenses installed?
Yes, we do provide service of lenses replacement on your glasses. We offer a huge selection of the world’s top
name brand lenses that can be installed into any eyewear frame. Choosing the best lenses for your needs is easy with the Glassesonweb.com .
The Lens Replacement service walks you step by step through the process of selecting lenses, in an easy, and quick way.
How long does it take to get my order?
The processing time is different depending on type of product. Some products available on stock and some should be ordered from warehouse. Occasionally, during the lens installation process frames or lenses become damaged and need to be reordered and reprocessed. This
can add to the overall time that it will take to get your eye glasses. Normally we are able to ship frames without lenses two business days after the order date. However, if we notice a problem
with your product we will have to reorder the item from the warehouse, which will add two days to your overall delivery time. Occasionally, eyeglass
frames and sunglasses can be backordered or discontinued without notice, adding additional time to your order. Order delivery time can be affected at every
stage by weather conditions in your area, and by holidays. Order delivery time is depend on shipping method you select at checkout stage.

How do I read my soft contact lenses prescription?
- POWER (sphere):
- The strength of your contact lenses which
is given as '+' or '-' with a numerical value
and a decimal point, such as '+2.5' or '-7.0'.
The '+' and the '-' are very important and
we need to know whether your fitting is '+'
or '-' when we order your lens for you. You
will find that the power for your right eye
(OD) may be different to the power for your
left eye (OS). Your contact lenses power is
not the same as that for your eyeglasses (spectacles).
- Bifocal lens :
- An Add Power usually from number +1.00 to +3.00.
- BC:
- The Base Curve which is the inside curve
of your contact lenses. This is a figure with
one decimal point, commonly 8.1 up to 8.9.
The figure is usually the same for both eyes.
- DIA:
- The Diameter of your contact lenses that
is recommended to fit your eye. This is a
figure with one decimal point such as 13.8,
14.0 or 14.5. The lens diameter fitted is
usually the same for both eyes.
If you have astigmatism, you will have been
fitted with a toric contact lens.
In addition to the above specification, toric
contact lenses wearers will have other figures
on their prescription. These are CYL (Cylinder)
and AXIS.
- CYL (Cylinder):
- Cylinder refers to the strength of you astigmatism.
The values are typically -0.75 up to -1.75.
Please note that the cylinder measurement
is given with a '-' sign.
- AXIS:
- Axis refers to the location of your astigmatism.
This measurement is given in degrees (º).
The values of AXIS may range from 10º
up to 180º.
