I quit using optometrists several years ago, and opted for an ophthalmologist. More of it was covered under my medical instead of vision. A few years back, she told me I had cataracts, and to keep a close watch on them. None of the eye glass places ever mentioned it to me, and maybe because it wasn't bad enough in their estimation, or maybe because the equipment wasn't as sophisticated, IDK. Anyway, a couple of years ago, she told me they qualified for insurance covered surgery. I opted for multi-focus lens implants which cost a bit of out of pocket $$. The "free" ones would allow you to choose near or far correction, which required glasses to cover the areas the lens didn't correct for. The multi-focus work from reading distance to far distance. I love them. I can read, use the camera, watch TV, and everything else with out requiring glasses. And what a big difference in viewing colors. The only time I need help is when doing really fine work or in low light. Bottom line is, as you age, go to an eye surgeon every so often for a muich more in depth eye exam. They perform a battery of tests that optometrists don't because they don't have all the additional equipment.
