According to internal military evaluations, the US Army is not a fan of Microsoft's augmented reality goggles.

Soldiers testing the headsets have complained that wearing goggles can cause headaches, nausea, and eyestrain. Acceptance of the tech remains low, with soldiers complaining that the headsets don't "contribute to their ability to complete their mission."

Insider reported one testimony that was very blunt. The tester said that the devices would have gotten them killed because of the light emitted by the goggles.

The Army thinks the tests are a success.

The hardware's reliability is one of the improvements that the reports point to. Insider was told that the tests of the goggles were a success.

According to the results, the program achieved success in most of the Army evaluation criteria. The Army will address areas where IVAS fell short as a result of the results.

Microsoft won several contracts to provide the US Army with its augmented reality glasses. The contracts have been seen as validation of Microsoft's augmented reality strategy. The goggles give soldiers live information on navigation and commands, as well as thermal and night-vision views.

$350 million of the Army's $400 million procurement request to buy more units from Microsoft was cut earlier this year by a Senate committee. The Army started taking delivery of the first 5,000 goggles in September this year.
