Hi all, I'm really nearsighted (-7 diopters), and came up with the following solution to the problem of VIDEO GOGGLES.
It's basically a ski goggle mod. But the key here is to get a pair of ski goggles that are designed to go over regular glasses (e.g. for people with really strong prescriptions, like me). This type of goggle has extra room in front and along the temples to handle most regular glasses. This one is an old pair of Smiths that I had sitting around, but I think most of the ski goggle manufacturers have a version. Added bonus is that with all the extra room there is zero fogging. It's great.
Basic ingredients: ski goggles, pair of Zeiss Cinemizer Plus, hot glue, goop, and electrical tape. I first removed the front of the goggles to dial in the position of the Cinemizers, which I held in place temporarily with duct tape. I then cut out the profile of the Cinemizers in the plastic front of the goggles using Stanley knife and tin snips. Next, I cut the temples shorter (about 2"), and removed the audio (since I prefer separate headphones anyway if I use them). This allows the stubs of the Cinemizer temples to run *outside* the face seal. To get the cord outside the face seal, I cut the face seal foam and re-glued with hot glue. After replacing front and positioning the Cinemizers in the hole, I glued in place to the plastic with hot glue (goop wherever there was rubber). I covered gaps with electrical tape, and then taped the front to block light. The remaining cable is duct taped to the elastic band like a Petzyl head torch. Result is shown in pictures.
This mod works best with small round or square spectacles, not wide or wrap around style glasses (chances are if you are very nearsighted your glasses are small to reduce bulk and weight anyway).
