I would look for a MSA. (medical savings account) The costs initially may be higher, but your savings are used for your deductible. As you continue to build your savings account, increase you deductible. As that increases, your insurance premuims will drop. Anything in your MSA can be used for medical purposes, including glasses, prescriptions ect.
For self employed folks, this is one of the best government plans going behind the IRA. Before I forget, monies in the account grow tax free.
