TL;DR: you now need to pay a $20/month “meta premium” subscription to use a 100% offline feature that runs on your own malware-ridden smartglasses.
If you don’t subscribe, you can use the feature that is already included in the hardware that you already paid for 3 hours each month
The now-paywalled feature boosts the voice of the speaker in front of you, something that even low-end ANC earphones are doing now. 5 minutes of free usage per day is basically nothing.
Depending on your visual impairment they may not help at all. For instance there are zero models that come with an astigmatism correction strong enough for me to use them.
I’m looking for something that could magnify text, or read text and convert it into, well digital text where I can adjust the size, like say from a menu behind the counter at a fast food restaurant. Or identify the walk / don’t walk sign across the street at a stop light intersection cross walk. Most of this can already be done simply by using the camera app and zoom features on any phone. So the next step is just getting the wearable form factor. And ensuring the HUD is actually readable with proper size, color and contrast. (Here “proper” means properly adjustable to accommodate the wearer’s needs. As that will vary.)
