I'm 71. I Bought Four Night-Driving Products and Every One of Them Was a Waste of Money. Here's the One Thing They All Had in Common.

I'll say it plainly, because I've already said it in four one-star reviews.

Night-driving products were a waste of money. Every one I bought.

I'm 71. I've bought four of them. Clip-ons, wraparounds, fit-overs, and a tinted thing that hangs off the sun visor. $114.83 all up. I kept the receipts, because I was raised to keep receipts.

Not one of them did what the box said. Not one.

And if you're reading this with a drawer full of yellow glasses, I'd bet you've had the same thought I had standing in the return line: how is this allowed on the shelf?

So no, I'm not going to tell you I found a miracle. I'm going to tell you what I bought, why every one of them failed the same way, and the one reason I was willing to try anything at all after that.

The clip-ons. $19.88. First thing I tried, because they were cheap and the picture on the package looked like somebody had turned the headlights down. They didn't turn anything down. The lights went yellow. Same glare, different color. I was just as blinded coming over the hill on Route 9, only now it was a yellow blind. Waste of money.

The wraparounds. $29.97. "HD night vision," it said on the front. I got them home and read the side of the box. In small print: NOT FOR NIGHT DRIVING. On the night-driving glasses. I'm not making that up. I took a photo of it and put it in my review.

The fit-overs. $39.99. These were the "good" ones. Polarized. Went over my regular glasses. My daughter-in-law said her father swears by them. The glare was still there, and now the whole road was darker too. I drove home from bingo feeling like I had sunglasses on at nine o'clock at night. Took them off halfway and never put them back.

The visor. $24.99. A tinted flip-down thing that clips to the sun visor. You pull it down when a car comes at you. I pulled it down. The headlights got dimmer. So did the mailbox, the deer crossing sign, and the edge of the road. I pushed it back up and drove the rest of the way with my hand over my eye like my mother used to.

Four products. Four reviews. Ripoff, waste of money, not as advertised, never again. I used all those words and I'd use them again.

Here's the part nobody told me, and it took me a kitchen table to work out.

I was boxing the fit-overs up one night. The lamp was on. And just to see how dark the things really were, I put them on and tried to read the newspaper.

Not "it was harder." I could not read the headline on the front page of a newspaper, under a lamp, in my own kitchen.

I took them off and sat there a minute. Then I got the clip-ons out of the junk box. Put those on. The newspaper went yellow and a shade dimmer. The wraparounds, same. I got the visor off the car and held it up in front of my face. Dimmer.

That's the whole trick. A tint can't tell a headlight from a mailbox. It takes a piece out of all of it. The headlight, yes. And the lane line. And the curb. And the deer standing on the shoulder.

In the daytime you've got light to spare, so you don't notice. At night, on a country road, you haven't got any to spare. Every bit they take is something you can't see anymore.

That's why it felt like wearing sunglasses at night. That's exactly what it was.

If you've bought these things and called them a waste of money, I'm not here to talk you out of it. You were right.

You weren't using them wrong. You didn't get a bad pair. They do exactly what they're built to do. They take light away. And light is the one thing a 71-year-old driving home in the dark has got the least of.

So they were never going to work. Not for me, not for you, not for anybody. At least one of the boxes says as much on the side, in small print, if you read it.

Once I saw what all four had in common, I saw the other thing too.

Every dollar I'd spent was on the light coming in. Not one cent on the eyes doing the looking.

I'd been treating my eyes like a windshield. Something you put a film over. It never once occurred to me that the eyes themselves need anything.

So I did two things. I booked an eye exam. My prescription had drifted. New lenses, clear ones.

And the second thing, I started reading about what's actually in an eye.

Two things stuck with me.

The clear fluid in the front of your eye carries vitamin C at 20 to 70 times the level in your blood. Your body goes out of its way to pile it up right there.

And the back of the eye carries some of the highest zinc levels of any tissue in the body.

I'm not telling you this to sound clever. I'm telling you because in four product boxes and four sets of instructions, nobody said one word about the eye. It was all tints and coatings and visors. The eyes were just where the glasses went.

Your body can't make vitamin C. It can't make zinc. They come from what you eat and what you take, every day, or they don't come at all.

I've been burned four times. So before I tell you what I take now, here's what it isn't. If any of this is a deal-breaker, stop reading and keep your money.

If you want something you'll feel by Friday, this isn't it. I'd rather lose you here than have you write the review I wrote four times.

I'll be honest. After four products I wasn't trying anything else. My sister Ruth sent me the link to Stay Able Vision Support and I told her I'd sooner set fire to the money.

Then I read the guarantee.

That's it. That's the one and only reason I ordered it. Not a doctor on the label. Not a study. Not a before-and-after. I've seen all of those on boxes that said NOT FOR NIGHT DRIVING on the side.

A company that puts 100 days and a refund in plain words is a company that expects you to keep it. I've never had a pair of yellow glasses offer me that.

A short list of things your eyes use every day. No tint, no coating, no visor.

Two capsules a day with breakfast. It supports healthy eyes as part of a daily routine. That's the claim. The whole claim.

The gadgets went in the junk box. This went on an index card.

1. Eye exam every year. Before you buy anything from anybody.
2. Clear lenses only. Nothing yellow, nothing tinted, nothing that takes light away.
3. Windshield clean inside and out, every week in winter. The film on the inside is worse than you think.
4. Headlight covers checked. Mine had gone cloudy. A $20 kit from the auto parts store.
5. Dash lights down low.
6. Slow down and look at the white line on your side of the road when a car comes at you.
7. Two Stay Able Vision Support capsules with breakfast. Looking after the eyes, not the windshield.

I'm not going to tell you a capsule fixed my night driving. It never claimed to, and I'd be no better than the clip-ons if I said it did.

Here's what I can tell you. I had the eye exam. New lenses, clear ones. I still drive in the daytime when I can, and I still slow down on Route 9.

The capsule is one line on the index card. With breakfast, like the coffee. Not a fix. One small thing for the eyes I've got, and I've stopped spending money on things that make the road darker.

The bottle's still here; I didn't send it back. The four products are going to the donation bin this week, box and all.

It's not for anyone still hoping for a magic pair of glasses. There isn't one. I've bought four.

I spent $114.83 on four things that live in a shoebox marked JUNK.

Stay Able Vision Support is $37.99 for a one-month bottle. If you'd rather not run out, Subscribe & Save brings it to $29.99 a month (that's the subscription price; skip or cancel anytime). 3-month supply $99.99, 6-month $179.99.

100-day money-back guarantee. If it's not for you, email us within 100 days and we'll refund you.

Choice one. Buy a fifth pair of glasses. Read the side of the box when it arrives. Write the review. Put it in the shoebox with the others.

Choice two. Get the eye exam. Put the checklist in your visor. And give the eyes doing the looking one small thing every morning, with 100 days to ask for a refund if you change your mind.

I've been burned four times. I wouldn't be writing this if I thought this was a fifth.

P.S. If you've still got your night-driving glasses, try them on at the kitchen table tonight and read the paper. Then decide if you want to buy another pair.

P.P.S. The eye exam first. Before this, before anything.
