Computational Phase-Modulated Eyeglasses
IEEE Transactions on Visualization and Computer Graphics, 2021We present computational phase-modulated eyeglasses, a see-through optical system that modulates the view of the user using phase-only spatial light modulators (PSLM). A PSLM is a programmable reflective device that can selectively retardate, or delay, the incoming light rays. As a result, a PSLM works as a computational dynamic lens device.

A prototype for the Bionic Eyeglass
2010 12th International Workshop on Cellular Nanoscale Networks and their Applications (CNNA 2010), 2010An experimental prototype for the Bionic Eyeglass will be demonstrated including three sample functions: pedestrian crosswalk detection, light detection and a basic color recognition. The prototype is built on the Bi-i visual computer, and uses a commercial cellular phone as a front-end towards the user.

The Use of Photochromic Eyeglasses by Radiologists
Radiology, 1975Photochromic lenses which undergo a change in density with varying intensities of sunlight have been incorporated into routine eyeglasses. Laboratory tests have shown that glasses of this type do not decrease the visual acuity of the radiologist.

Eyeglasses and Gender Stereotypes
Optometry and Vision Science, 1989Under the guise of forming impressions of a job applicant in a hiring interview, subjects rated a videotaped male or female stimulus person (SP) on several gender stereotypical and task relevant traits. In one condition, the SP's wore eyeglasses, and in the other condition they did not.

Ectropion Produced by Eyeglass Frames
Archives of Ophthalmology, 1979• Two patients had nonspecific, but severe, symptoms of ocular irritation. In each case, full ophthalmologic examination failed to show a cause for the irritation. When the patients were observed wearing their eyeglasses, an ectropion, caused by the eyeglass frames, was observed. Changing the frames produced complete relief of symptoms in one patient.

Ultrasonic eyeglasses for the blind
The Journal of the Acoustical Society of America, 2000There is an obvious need for blind persons to perceive their environment in the greatest detail possible. The bat has demonstrated the effective use of ultrasonic waves for its own purpose of perceiving its environment. Man now has his own air-sonar technology, in the form of eyeglasses mounted on the head, so as to perceive his environment.
