The Tarsier Eclipse ™ is the most advanced Night Vision Goggle (NVG) accessory on the market, allowing the operator to see objects from 3" to infinity at the same time and without loss of clarity. It incorporates a smooth action, high performance optical iris that can quickly be adjusted depending on the amount of ambient light.  Additionally, the Tarsier Eclipse ™ offers a high-quality Corning Glass sacrificial lens that can quickly be replaced without tools. The sacrificial lens serves as a critical piece of protection for your NVG lenses, shielding them from dust, dirt or scratching that may cause expensive repairs and potential downtime. 

Included in a Tarsier Eclipse kit are 2 x Tarsier Eclipse ™ (880021-NAVAIR or 880021- GROUND ), an additional Sacrificial Lens, cleaning kit and 2 lanyards with swivel hook attachment. 

  • Provides the ability to see objects at all distances without adjusting the focus on Night Vision Goggles.

  • Infinitely variable from open to close to allow the optimal amount of light into the NVGs and maintain auto-focus capability.

  • Clear front sacrificial lens to protect lens of NVGs and prevent dust and debris from entering apparatus.

  • Rapid adaptation to ambient light by turning the adjustment ring, opening or closing the iris.

  • Easy and secure attachment to end of NVGs.

      Fast shipping, but for what it’s worth… these are not worth $240 PER cover. Save your money and do the diy. Still a quality product but definitely over priced

      Excellently designed and executed piece of kit

      Takes a few turns to break them in however after that they run smooth like butter. Operation is simplistic, precise and expedient under stress. The ability to "dial in" the exact light transmissivity level is a game changer when engaged in environments requiring multiple focal ranges. The sacrificial lens quality is excellent with no degradation, aberration of the image or lens flare. My only recommendation would be to upgrade the lanyard, but hey, it works! The Matbock Tarsier Eclipse is the Alpha and Omega of protection and function for NODs, the solid mounting, intuitive focal shift and sacrificial lens ensure you will achieve maximum utilization of your unit and not loose your gear due to gravel kicked up, or debris blowback from your suppressed gear.

      Tarsier Eclipse ™ Kit - Awesome!

      I served in the infantry in Iraq from 2003-2005 and wish we had something like this back then. I was actually thinking about getting rid of my PVS-31 because I was getting tired of not being in focus when going from outdoors to indoors. Now, I love my 31s and the Tarsier Eclipse!! Great product!!!

      tarsier eclipse

      got them for my RNVG, best accessories for the unit, faster near focus and also act as a brightness adjustment tool

      These are awesome

      It is nice not having to adjust focus. Hands, weapons and targets are all crystal clear. They make it much easier Starting IV’s and doing trauma assessments as well.

      A must for night vision

      This item is great it is a must for CQB applications. Feels extremely smooth and durable.



      Thanks for the great support and awesome review!

      Works as expected

      These lenses are expensive, but to be able to dial to the exact light transmission you prefer is a plus. Of course this also affects your depth perception up close, but can be changed on the fly. Helps with passive aiming too. Outside of pin holes in the lens caps that came with the goggles, these are the only solutions I’ve used, so can’t speak to the merits of any other ones, but they’re solid for sure. They’re a little stiff to dial out of the box, but seem to be loosening up with extended use + additional Teflon oil.



      Thanks for the review Nicholas, if they do not loosen up to your liking let us know!

      Love it

      Legit for driving and fine up close use and increased field of view. Shot an indoor night match with an enfield 38 revolver and still took 8th out of 30

      Works well

      Easy to use. Works well as described. My only complaint is that when making adjustments to the Tarsiers, the objective lens on my DTNVG spins, creating a degraded image. I had to apply tape to the objective lens to prevent them from moving.

      Tarsier Eclipse

      Great product but very expensive and not sure it warrants the price tag. I think this product would sell significantly better if priced at 125 and would be considered a requirement for anyone running nvgs.

      Refocus done right

      Purchase, slip on, then perfection!!! No really it is, Easy on the fly refocus like it was meant to be. Price is a high, but so is the customer service and the quality of the Tarsier. If you are on the fence, I would recommend taking the leap. Would buy again 100%



      Chad, thank you for the support and the great review!

      Good, but only after some tweaks

      First off, they took 3 months to get here. For an instant gratification guy, that ******. Thank they were geey sticky.They would adjust the focus instead of the iris. When you buy 2, they give you the lube kit and extra sacrificial lens for free. I suppose if you only buy one, you will also neednto biy the lube.Hopefully they will include yhe luve free, or fix the sticking problem. Once all that was done , and i finally got them in my hot little hand, they worked as advertised. I even got a free hat. Thanks guys and gals!



      Chris, thank you for the review. We apologize for the long wait we had some issues obtaining materials the last few months and some operational shutdowns over the holidays. As for the sticking problem, they usually have a small break-in period that can be jump started with the dry teflon lube. If you have any additional issues please email sales@matbock.com

      Benefits vs Cost

      The purpose for these eclipses are substantial and help with NVG usage and focus. But improvements can be made to the current design. I can reason with purchasing a pair for 50% off, not full msrp. I also expect either smaller profile eclipses with more firm fit as well as a more slim profile on the eclipse lense.

      every set of nods should come with these

      although pricey, well worth the money. provides protection, ability to adjust aperture, etc

      Great product fast shipping.

      These make a world of difference on close range fucus and controlling light intake.
