Well, your are like me, also in my mid sixties. We are over 45 years of age, which is the key age on the table.
That means that even if you are one of those lucky SOBs who had 20/20 vision when younger, that you are (or should be) wearing lenses for anything close. That is everyone in the population, folks. No one over 45 has good close vision.
I assume, for safety's sake at least, that you want lenses that let you read the instruments and dash controls clearly as well as let you see very well at infinity down the road.
So, the expensive choice is to go to your optometrist and get high quality prescription sunglasses. I did that for many years, even getting polarized prescription lenses. But, be careful here. There is both good stuff and junk available from licensed opticians, including some of the chains which see these as high margin up sales. Some prescription sunglasses are really cheap things where a clear lens is basically dipped in liquid dye. Not exactly precision work, and they can change over time.
Another thing to look out for are dark blanks that are the same density of light absorbing color throughout the lens material before it is ground. Once a Rx gets strong, the thick parts of the lens will be darker than the thin parts. Depends whether you are nearsighted or farsighted as to whether the edges or middle are the light or dark areas.
So, the only very good Rx sunglasses are the ones that are made of a sandwich of materials with the light absorbing material in the middle with constant density across the width of the blank. That way, the density of light absorption is exactly uniform across the lens even after it is ground to your prescription. Still, even then, most Rx suns are not polarized which means that it is still difficult to see through the reflections on the windows of the vehicles in front of you, a real safety margin to give up in heavy traffic.
So, you are relegated to clip ons to modify your Rx regular glasses if your want a reasonable price. All of the style statements of the young ones below are basically irrelevant to most folks over 45 years of age (or those who have worn prescription lenses all of their lives) and who still want to see their instrument panel as well as look down the road. Most of the style names do not market clip ons, or they have a clunky one size that fits all with a giant claw clamp in the middle. Not good for the field of vision and not good for a plastic lens surface.
Some clip ons are made to exactly match the frames purchased with your Rx by the same company that makes the frames. Nice fit, but they can be very pricey. My last set cost $72, and that is a figure from many years ago. I am sure it is much more now. And, again, many of those style match clip ons are not polarized.
So, my optometrist and optician now both tell me to get el cheapo clip ons that will fit the Rx frames fairly closely.
I hate Walmart, but out here in the hinterlands it is very hard to find anyone else that carries an assortment of clip ons in different sizes. Less that $10, polarized, and they come in an assortment of sizes that will fit most prescription frames that are out there. A set lives in each of my cars. If I misplace them, easily replaced with little pain.
Or, vanity can set in. Buy the fancy style names --- and have blurry instruments, and look cool. To others. Not yourself though, since you will not see yourself clearly at close range in the mirror He He.
Just my $.02 from a lot of experience in this department.
