NightSight™ Healthy Vision Formula

Why Driving at Night Feels Different Over Time

For many people, the first noticeable changes in vision don’t happen during the day — they happen at night.

Headlights may feel more intense. Road signs may seem harder to read. Your eyes may take longer to adjust when moving between light and dark.

That’s because, as we age, the eyes can become more sensitive to glare and slower to adapt in low-light environments.

These changes can make nighttime driving feel more stressful and less comfortable than it once did.

NightSight™ is designed to support your eyes in these moments — helping support visual performance when lighting conditions are at their most challenging.*

So you can feel more confident on the road, out at night, and in any low-light setting.

Targeted Ingredients for Day + Night Vision

NightSight™ combines clinically studied ingredients selected to support how your eyes perform in real-world conditions — from bright daylight to low-light environments.

150 mg

European Black Currant Extract

Provides anthocyanins studied for their role in supporting dark adaptation and low-light visual performance.*

10 mg

FloraGLO® Lutein

Supports retinal health and helps filter blue light exposure during the day.*

2 mg

OPTISHARP® Zeaxanthin

Supports visual clarity and helps the eyes respond to bright light and glare.*

Science That Supports Low-Light Vision

Your ability to see clearly — especially at night — depends on how well your eyes respond to changing light conditions.

Ingredients like lutein and zeaxanthin have been studied for their role in supporting macular pigment density and visual performance — both important for maintaining clarity in both daylight and nighttime conditions.*

Because better vision isn’t just about what you see — it’s about how your eyes perform across every lighting condition.

A miracle for me

A friend told me about Night Sight, and after only four days I could SEE and DRIVE AT NIGHT! I was so excited that when I got to Target that night I started to cry. I could read the road signs! Glare from headlights didn't bother me as much! I have been taking this for four years now and will never be without it. It works!!!!!!!

Reviews

Seem to be effective!

"I spend my work day in front of a computer and my off hours cooking or working on projects, and have been having more difficulty adjusting near/far focus in the past few years, and thought this was worth a shot. I take these with my morning multivitamin, and though I started off somewhat skeptical that there would be a noticable difference, I did notice better clarity and less glare at night after only a few days. I won't be throwing away my contacts or reading glasses but I'm pleasantly surprised with this supplement."

— Tom (5/5)

Solid supplement

"I’ve been happy with this supplement so far. The capsules are easy to take, and the ingredients seem thoughtfully selected for eye health. The product arrived fresh and well-packaged, and the quality meets my expectations. Overall, it seems like a good product, and I’m looking forward to continuing to use it."

— Dadman (5/5)

blurry halos

"I have been having some issues with glare while driving at night. I have been taking these for about 3 weeks now, and I have noticed a difference in the sharpness of sight at night. I was a bit skeptical about these at first, but the supplement definitely seems to reduce the glare or "halo" around objectas while driving at night."

Helps me see better on the computer

"I definitely noticed a difference. I work nights and I’m on a computer pretty often."

— Steve C. (5/5)

Support for Night Glare

"I spend a lot of time driving, including early mornings, late evenings, and Florida rain storms, so I decided to give NightSight a try to support my vision as I get older. After taking it consistently, I’ve definitely noticed improvements in visual comfort, especially in challenging conditions. Much less eye strain. One thing that stood out to me was driving at sunset and during a heavy rains, situations where glare and reflections normally bother me quite a bit. Everything just seemed clearer and less straining on my eyes. I’ve also noticed less discomfort from headlights while driving at night. It's one of those things that after the drive you realize that the drive was easier and the strain wasn't there. I’m realistic, this isn’t some miracle overnight change, but I do feel like my eyes are handling low-light conditions and glare better than before. That alone has made it worthwhile for me. Easy to take and now part of my daily routine."

— Keith (5/5)

A miracle for me

"I have always had poor night vision. It was so bad that I'd go to a new location in the daytime so I wouldn't get lost when driving there at night. A friend told me about Night Sight, and after only four days I could SEE and DRIVE AT NIGHT! I was so excited that when I got to Target that night I started to cry. I could read the road signs! Glare from headlights didn't bother me as much! I have been taking this for four years now and will never be without it. It works!!!!!!!"
