With the convenience of online and catalog shopping these days, buying contact lenses, and everything else for that matter, can be done by post or through the Internet. If you prefer to do it this way, rather than buying a pair directly from the store, here are the things you have to consider:

1. Make sure that the contact lenses you chose exactly fits your prescription. Contact lenses come in a variety of types, shapes, and designs. And to top it all, contact lenses are medical devices. You have to carefully check the products on the catalog if they are the one appropriate for you. Do not settle for the type that's good enough. Be perfectly sure.

2. Check if your special requests can be granted. If you require unique specifications, like you need a toric contact lenses for one eye and a normal one for the other, the catalog might not granted that outright. You first have to make sure that requests like these can be accommodated and assured.

3. Consider the price. When buying contact lenses by post, you have to add other charges like shipping and applicable taxes. The cover price is not all you are going to pay. And if you pay through credit card, another set of fees will apply.

4. Take note of the delivery option. If your pair of contact lenses is readily available, then you can expect the delivery the soonest time possible. But if the suppliers say that your specialized pair needs to be manufactured in a week or so, then expect the package to be delivered in two weeks the earliest. You might also need to pay extra for faster shipping.

5. Do a background check on the company. For starters, make sure that the company that released the catalog is an established one. It is always good to transact with an honestly straight company. That way, you'll be sure to experience good customer service as well.

6. Scrutinize each pair. Do this if you are going for a pair of contact lenses mainly because of its style and design. Remember, the photo may not appear to be exactly as the actual thing. Read the product description. It will guide you more in your selection.

These are the six basic things that you have to consider when buying contact lenses by post. It is advisable for you to buy from catalogs if you feel that time saved is more important than the time enjoyed inside the mall.
