Pay out of pocket for eye exams and glasses. about $300 every 2 years. You can find cheaper but I prefer the doctor I have. I didn't check on optical insurance. If it becomes a medical condition, Medicare will cover it.
Pay out of pocket for dental 2 cleanings per year about $100 each time. I put the money in the bank for those things. I checked into dental and it was too pricey for what I need. If you have major dental work ahead you might want to consider a plan but be prepared for high premiums, deductibles and co-pays.
