Check out Bruce McColloch's glasses in this classic sketch:
If anyone has any information about the style and/or brand of glasses he's wearing, please let me know because I think they're great.
Kevin McDonald's glasses are pretty hilarious in this too.

Prescription Lenses with Prism Online
Online eyeglass retailers can generally handle most prescriptions. However, there are a couple exceptions. In my case, I have prism correction in my prescription. Many online glasses stores won't do prism at all. However, there are some options out there.
First it's important to understand the purpose of prism correction. People who require prism correction usually have eyes that don't work together correctly. The brain thinks the eyes are pointing in the same direction, but in fact they are not. The result is diplopia, or double vision. Prism corrects this problem by nudging the light back in line.
So why do retailers refuse to produce lenses with prism? I don't know for sure. But in my research, I have read a lot of anecdotes about difficulties in adjusting glasses with prism. It seems that at least in certain cases the customer may need very precise adjustments to their glasses and therefore a full-service optician is required. Either way, it's best to consult your optometrist and optician to understand your needs. In my case, I have a small amount of prism (2 in on each eye) and have had no problems with any of the glasses I've purchased online.
The place to start is Optical4Less. It's the easiest one to use because they include prism on their standard form for entering prescriptions. Their prices are very good for the quality of frames and lenses, and prism costs $3 per degree of correction on top of the base cost of the glasses.
Another option is to send your frames to a company like Eyeglass Lens Direct who will produce frame with prism correction and mount them in your glasses. I will do a full review of them in a later post, but the important note for this post is that any lens they offer marked "extended range" will accommodate prism correction. So all you need to find frames, no need for prescription lenses. You can find lots of cheap frames on eBay, and some retailers like Zenni Optical will give you discounts if you request demo lenses instead of optical lenses.

The Adventure Begins
Hello everyone!
I'm a big fan of eyewear. In the past I haven't been able to indulge my love of glasses due to their high retail costs. The internet has changed all this. I'm going glasses crazy!
