health insurance and eyeglasses not covered?

i have health insurance with blue-cross blue-shield. I have recently discovered that my plan covers my eye exam but not my eyeglasses. Does anyone know of a reasonably priced plan or provider that does? ( i currently pay $170) Or know of a supplemental policy?

Talk to your HR department. Most BCBS insurances have an optional vision plan. They usually pay a blanket cost of $100-$200 for exam and materials.
