Why Night Driving Often Gets Harder After 50 — and the 2 Pigments Behind Sharp Central Vision

Headlights that seem brighter than they used to. A menu held a little farther away. Here's the part of the eye behind those everyday moments, and the two nutrients it's built from.

The moment nobody talks about

It usually happens quietly. Someone says, "I'll drive, it's getting dark," and everyone goes along with it. Or the phone flashlight comes out at a dim restaurant, again.

Eyes change with age, and plenty of those changes have nothing to do with needing new readers. Sharp, detailed central vision depends on one small spot at the back of the eye.

Meet the macula

The macula is a small area in the center of the retina. At its middle sits the fovea, the part of the eye with the sharpest vision.² It's what you use to read a street sign, a recipe card or a grandchild's face across the table.

The macula has something no other part of the eye has in the same amount: a yellow pigment. Researchers call it macular pigment, and it's made largely of two nutrients, lutein and zeaxanthin.²

Your body can't make them

Here's the catch. People don't produce lutein or zeaxanthin. Like other carotenoids, they have to come from food.² Leafy greens like spinach and kale are the richest sources, and egg yolks are another good one.²

The eye is picky about them. Lutein and zeaxanthin are concentrated in the macula, and in the very center of it, the fovea, levels are about 100 times higher than elsewhere in the eye.² There, the pigment absorbs blue light.²

The gap on most plates

National survey data put the average U.S. adult at about 1.7 mg of lutein and zeaxanthin a day.² The National Eye Institute's AREDS2 formula used 12 mg a day: 10 mg lutein and 2 mg zeaxanthin.¹

Eating more greens is the first step, and we'd tell anyone that. A daily supplement is a simple way to add these two nutrients on the days the salad doesn't happen.

What we sell, plainly

Our formula provides lutein 10 mg, zeaxanthin 2 mg, vitamin C 500 mg, vitamin E 180 mg, zinc 80 mg and copper 2 mg per daily serving. No beta-carotene. It ships in the bottle pictured. No subscription, nothing auto-renews.

Supplements work gradually; take it daily as the label directs. It doesn't replace glasses or a regular eye exam, and it isn't meant to treat any eye condition.* High-dose zinc: don't combine with other zinc or eye vitamins without asking your doctor.
