Getting an eye exam every few years or so is a good idea even though you don't wear eyeglasses or contact lenses.
Having an eye exam done is around $100.00 to $200.00 depending on who you go to for the eye exam and you will find out early if you need eyeglasses or contact lenses.
I go to Walmart Vision Center once a year for an eye exam even though I don't wear eye glasses or contact lenses because I just want to make sure my eyes are healthy.
The Walmart Vision Center is only $80.00 for the eye exam and is well worth the cost every year to check my eye health.
