1. A wearable head device comprising:
a see-through display configured to present content to an eye of a user of the wearable head device, such that presenting the content to the eye produces an eye glint;
a combiner;
one or more sensors configured to capture an image of the eye glint; and
one or more processors,
wherein:
the eye glint comprises light of a first wavelength,
the combiner is configured to absorb light of the first wavelength,
the one or more sensors are configured to detect light of the first wavelength,
the content comprises visible light, and
the one or more processors are configured to perform a method comprising:
capturing, via the one or more sensors, an image of the eye glint, wherein the image of the eye glint comprises a portion of the content reflected from the eye;
determining, based on the image of the eye glint, a focus of the content;
determining whether the focus of the content is below an image quality threshold;
in accordance with a determination that the focus of the content is below the image quality threshold, adjusting the focus of the content; and
in accordance with a determination that the focus of the content is not below the image quality threshold, forgoing adjusting the focus of the content.
