If you’ve been shopping around for tritium night sights, chances are you’ve come across Night Fision a time or two. And there’s a good reason for that. While the company might be overshadowed by its competitors, Night Fision has serious experience with tritium. Their sister company, Cammenga, has been making tritium lensatic compasses for the U.S. military for over 30 years. So yeah, they know their stuff.
But enough about the backstory—let’s cut to the chase. What makes Night Fision sights stand out, and what are the key designs they offer?
The Perfect Dot Technology Actually Works
Most tritium sights use aluminum sleeves with painted white rings around the tritium vials. Night Fision threw that design out the window. Instead, they use the “Perfect Dot” injection molded sleeve design. In simple words, the high-vis polymer ring on Night Fision Perfect Dot sights isn’t painted but molded, which addresses two major issues: durability and visibility.
Being an integral part of the sight’s structure, the Perfect Dot ring is injected through the lens, so nothing flakes off under solvent or ultrasonic cleaning. In contrast, painted rings chip, fade, and wear off over time.
Then, the ring is very bright. You can choose from five colors: white, blue, yellow, orange, or red. The yellow and orange options are particularly effective because they’re among the last colors your eyes lose in low light.
That said, the colored rings can make the tritium holes appear smaller, but the overall brightness more than compensates. The front sight becomes incredibly easy to acquire, even for those with vision issues or astigmatism.
Finally, the Perfect Dot ring uses fluorescent properties, meaning it absorbs ambient light during the day and glows slightly even without the tritium. This not only helps in lowlight but also creates a bright front sight for daylight that remains hi-vis even in overcast conditions.
30% More Tritium Makes a Real Difference
Night Fision claims their night sights contain 30% more tritium than competitors, and based on side-by-side comparisons, this isn’t just marketing speak. In unlit and backlit rooms, Night Fision’s front lamp does appear visibly brighter than other other tritium sight brands.
The science behind it is pretty straightforward. Night Fision fills a slightly larger glass lamp (so there’s more tritium gas) and adds a moulded, slightly domed lens. Unlike a flat lens, the domed design focuses the tritium rays, creating a sharper and more intense glow.
Besides increased brightness, greater tritium content contributes to longer lifespan. While most tritium sights are guaranteed for 12 years, Night Fision backs theirs for 16 years.
The Borosilicate Glass
Tritium is a radioactive isotope of hydrogen. While it’s safe in properly manufactured sights, it can only be completely contained by borosilicate glass, the same material used in laboratory equipment. Other materials allow some tritium to escape over time, potentially undermining longevity. Night Fision sights do utilize borosilicate glass.
The Overview of Night Fision Tritium Sights
Now, let’s take a look at all the popular Night Fision sights series:
Standard Height Perfect Dot
The bread-and-butter option, available with square or U-notch rear sights. The U-notch provides slightly more space around the front sight, which some shooters prefer for faster target acquisition.
These sights sit lower than some competitors like Trijicon HD, creating a more streamlined profile that’s less likely to snag on clothing or holsters.

Suppressor Height
Night Fision Suppressor Height Sights are basically taller versions of standard OEM replacement sights, designed to clear suppressors. At the core, they are the same Perfect Dot sights but redesigned for a lower 1/3 co-witness with red dot optics. However, as red dot optics have been evolving into more compact designs, these sights may partially obstruct the red dot window on slimmer optics. All in all, they’re a good choice for those who want sights that work well with suppressors and larger red dots.

Optics Ready Stealth Series
The Optics Ready Stealth sights are shorter than Suppressor Height sights to avoid blocking the window of a carry size red dot. They also have domed lenses for brighter tritium, serrations to reduce glare, and a wider rear notch for quicker aiming. They’re made to give shooters a simple, distraction-free experience with their red dot optics.

Real-World Performance
Multiple reviewers have noted that Night Fision sights tend to shoot slightly low when using traditional three-dot alignment. This isn’t necessarily a flaw—many defensive shooting instructors prefer a slightly low point of impact for center-mass hits.
The front sight is substantial enough to be easily acquired but not so large as to obscure targets at distance. The Perfect Dot measures approximately 0.142 inches, making it suitable for both close-range defensive work and precision shooting out to 25 yards.
Also, the rear sight features a true 90-degree face, making one-handed slide manipulation much easier than sights with angled faces. This is crucial for defensive applications where you might need to rack the slide against a belt, holster, or other object.
Installation and Compatibility
Night Fision sights install like any quality aftermarket sight using standard dovetail specifications. The company provides detailed installation videos, though most shooters opt for professional installation to ensure proper alignment.
Current compatibility includes:
- Glock (all major models)
- Sig Sauer P320, P365, P226, P229
- Smith & Wesson M&P series
- CZ P10, P07, P09, 75
- Springfield XD, XDM, Hellcat
- Canik TP9 and Mete SF series
- as well as Beretta, HK, FN, Ruger, Shadow Systems, Taurus, Walther, and 1911 pistols.
The Optics Mounted Stealth series (with the rear sight mounting directly onto the red dot battery pack) works with the most popular RMR footprint red dots, like Trijicon RMR or Holosun 507C.
Pricing and Value
Night Fision sights typically retail for $90-115 for a complete set, positioning them about $20-30 below premium options like Trijicon HD or Ameriglo Pro series.
The front sight alone runs approximately $48, making it an affordable upgrade for shooters who prefer blacked-out rears.
Given the 16-year warranty, proven brightness, and build quality, Night Fision sights represent great value in the tritium sight market. The cost per year of use is actually lower than many competitors due to the extended warranty period.
Minor Considerations
Night Fision sights do have a few characteristics worth noting:
The Perfect Dot rings, while more durable than paint, do make the tritium vials appear slightly smaller during daylight use. The increased brightness generally compensates for this, but it’s noticeable when comparing to sights with larger tritium windows.
The lower profile compared to some competitors means they won’t co-witness with all red dot optics. If you’re planning to use them with a specific optic, verify the height requirements before ordering.
Some shooters report a brief adjustment period when switching from taller sights. The lower profile changes the sight picture slightly, though most adapt quickly.
Finally, if you’re transitioning from Trijicon sights, keep in mind that the fluorescent ring on Night Fisions glows brightly when exposed to an external light source and stops glowing when the light is removed, while photo-luminescent paint on Trijicons absorbs light and then continues to glow in the dark for several minutes after the light source is gone.
Final Thoughts
For most defensive shooters, Night Fision sights offer an excellent balance of performance, durability, and value. They’re bright enough for serious low-light work, tough enough for daily carry, and priced competitively against other brands.
