Apple Vision Pro doesn't even have a firm release date yet and the Cupertino-based tech giant is already running into problems with the device.

In the latest edition of his Power On newsletter, Bloomberg's Mark Gurman (a reliable source of insider Apple info) reported that Apple is currently wrestling with a couple of medium-grade concerns with its upcoming mixed reality headset. Namely, it might weigh too much and getting prescription lenses for people with vision problems might be problematic.

The first of those two issues is pretty simple to grasp. As it stands, Vision Pro weighs around one pound, and wearing something that heavy on your head for an extended period of time can cause neck strain. Gurman said Apple might alleviate the issue on the first Vision Pro with straps, but a more sustainable solution is to simply make future iterations more lightweight.

As for prescription lenses, a big problem with Vision Pro is that you can't really wear glasses with the headset, a decision Apple made to keep the device from being too bulky. Apple partnered with a company called Zeiss to provide prescription lenses that attach to the Vision Pro, but Gurman called it a "headache" to provide a variety of different lens options to customers.

The company could make custom headsets with prescription lenses built-in and ship those directly to consumers, but then the device might be unusable by other people (or even by the original owner if their prescription shifts over time). It's tricky and it doesn't appear that Apple has a bonafide, slam-dunk solution to the problem yet.

That's just how it goes with new tech, I guess. It takes time to figure these things out.
