Ask HN: Instead of autofocus glasses, why not have auto "focus mode" glasses?
The concept of auto focus mode glasses is proposed as an alternative to autofocus glasses. This idea utilizes the capability of devices such as iPhones to detect when they are being looked at and automatically adjust the glasses' focus accordingly. The technology could potentially be expanded to other devices like Macs, allowing for seamless transitions between different focus modes.
- ▪iPhones can detect when a user is looking at them and communicate with glasses to adjust focus.
- ▪The proposed auto focus mode glasses would use the user's prescription adjusted for device usage.
- ▪The technology could potentially be integrated with Macs for computer usage focus modes.

iPhones can already tell when you are looking at them.So they could automatically communicate with your glasses to tell them to go into iPhone focus mode. This would use your prescription but adjusted for phone usage.And maybe in the future, Macs would be able to do something similar so your glasses would use your prescription adjusted for computer usage.So instead of trying to determine distance by looking at eye alignment, which is problematic in some people with eye alignment issues, you just automatically switch between focus modes based on device feedback.
