Samitivej Hospital near here told me the following. 1. We do not sell eyeglasses, we only do exams. 2. When I asked how much for an eye exam they said, it depends on the Doctor..3. Plus, admin fee, registration fee, extra charges, cleaning fee, parking fee and opening the front door fee, trying to push open the exit door fee but it was broken and using the lift fee, and the pay toilet fee (paid in cash). They let me off on the broken door fee.
