Yes, I want to tell you VSP is a big ripoff especially for glasses. You are only allowed to go to a private practice optometry shop. You can not go to lenscrafters, macy's, wal-mart, costco, etc. You will end up paying more because private practice makes money on the lenses. The frames are competitive in price but still a huge upcharge compared to retail shops.
VSP wants to protect private practice and only gives you that choice, but in the real world we need choice. That's what insurance is suppose to allow us to have. To save money anywhere for this service. The optometrist at Lenscrafters or Target can do just as good of a job as in private practice. Eyemed is accepted at Lenscrafters and private practice. Optum Health from United Healthcare is accepted everywhere. There are so many choices out there besides VSP. Why is VSP so popular? It's because the brokers that sell VSP make a substantially larger commission compared to the other plans. Plain and simple. It's a win for the insurance brokers, and it's a loss for consumers.
VSP will tell the consumer that they have a retail choice (ex. Costco), but they chose them because you must have a membership to get in. They also put Costco at the bottom of the web directory search and put all of the private practice doctors at the top. This gives you an illusion that there is a choice, but they tell the private practice doctors not to worry because Costco is "Out of Network." That means Costco is not allowed to tell customers or advertise that they accept VSP. It's an unfair disadvantage. Since Costco is out of network, your insurance benefits are worse compared to an "In Network" private practice doctor. They tell the customer one thing, but they tell the doctors something different. It's the only vision plan that does it.
Also look up VSP's shady tax scam past. They got their "non-profit" privileges revoked. They are definitely a for profit company, but got away with millions of dollars tax free. They finally paid a fine but not as much as they should.
