Default How Hard is it to Change Contact Lens Brands On Line?

I've heard that when you order your contacts on line, you give them all the information on the prescription, which includes the brand the eye doctor recommends.

Why does the eye doctor specify a brand? Can't the patient shop around? If they order on line, I've heard it's hard to change the brand. Why is that?

It should not be that hard to change brands as long as it is one that the prescription is written for that brand, that is if the doctor says it is ok to order either contact lens, very common in cases where people want more than one colored contact lens.
The more interesting part of the question is why they can't shop around, you can buy something like aspirin made by different companies but the product is essentially the same.
The difference in contact lenses are that one brands contact is not the exact same lens as anothers, they will not be the same base curve, diameter and material. They might have 1 or 2 of the same parameters but not all three. I believe it is because each lens a company gets FDA approval for is also patented so someone cannot wait and see how one company's lens does then just copy the same lens.

I never thought about that patent thing. That makes sense. Do eye doctors commonly write a prescription that has two or more brand names on it?

Not regularly since typically you will determine exactly what someone wants to wear. Where we see it most is when someones wants different colored lenses so they end up with different brands in the same power.
