In the past week, I have been hit up twice for this information, so the time is right for the blog post.
Almost 2 years ago, I realized that I needed glasses. The 20/10’s of my youth were done. I got a very nice pair at one of the cool places in Seattle. They fit great and looked really good, but they were not me 24/7. I came across the sites below and thought it would be interesting to try. At the same time, a friend who really needs glasses had his last pair broken for him (that is another story). I sent him these links and he ended up getting a couple of pairs. They looked great. Worked great, even bifocals. Encouraged I took the plunge and have been very satisfied. To date, I have ordered from Zenni, Coastal Contacts and EyeBuyDirect.
What you need
You need your prescription and pupillary distance. Also you need to know the frame dimensions that work on your face. For the first couple of pairs, I mirrored my expensive, very nice, cool store pair. After that I learned what would work and branched out from there. I have about 4 pairs that I rotate and 2 $8 pairs for backup and glassblowing.
Where I have bought
Zenni Optical Dirt cheap prices and solid quality. Only $5 to ship, but can take up awhile to deliver.
Coastal Contacts More designer frames than other sites and prices range accordingly. Super fast shipping.
EyeBuyDirect Great turnaround. I had my order within 7 days. My current favorite pair is from here.
