Many people choose to wear contact lenses instead of, or as well as, eyeglasses. Contact lenses are popular, not only for cosmetic reasons but also because they are really convenient.
If you have to go to see an optometrist for a repeat prescription each time you run out of contact lenses, that is not at all convenient.
The good news is that it is really easy to reorder contact lenses online, and you can order several boxes at a time so that you have a good supply and don’t have to reorder each month.
So what information do you need to put through an online order?
You should have a copy of your prescription from your last visit to the optometrist or ophthalmologist, but if you don’t, you will be able to locate all the information you need on your contact lens packaging.
If you are reordering regular contact lenses, you will need to know the following information:
- The brand and product name you require
- Base Curve (BC). This will be a number between 8.0 and 10.0
- Diameter (DIA). This will be a number between 13.0 and 15.0
- Power/Sphere/Rx. This is the strength of your prescription and will be a number between -20.00 and +20.00
You will need to provide this information for each eye. The right eye will be written as OD, while OS is the left eye.
If you have astigmatism, you will need to provide all of the information needed for regular lenses. On top of that, you will also need to provide:
- This will be a number between -4.00 and +4.00
- This will be a degree between 0° and 180°
You will usually find the cylinder and axis figures separated by a times (X) symbol.
If you wear bifocals, you will also have a number between +0.25 and +5.00 to add. You may also have a word or phrase describing the color tint of the lenses.
Reordering contact lenses online is usually a very straightforward process. You will generally need to fill out an online form with all of your prescription information, as well as your name, delivery address and contact information, and your payment details.
After the contact lenses sale has gone through, you should then receive a follow-up call from a trained professional to go over your order and confirm that the information given is all correct.
The contact lenses will then be shipped straight to your address; there is no need to make a trip to the store.
