Vision care plans are most often offered as an additional feature on HMO or PPO plans. However, they can be purchased separately as well.
What do vision plans cover? Most vision care plans cover the cost of a yearly eye exam (or require only a small copayment) by an approved optometrist under contract to the plan. Some also allow a certain discount for a pair of glasses or contact lenses.
What don't vision plans cover? Generally, these plans do not cover
things like surgery or other treatment for vision problems like glaucoma or
cataracts. These types of problems are most likely covered by your medical plan
