The materials that have been reported as causing allergic contact dermatitis within spectacle frames are identified, and their most likely location on the frame is highlighted. The lack of any real control over spectacle frame quality and content is indicated to be a problem, as is the difficulty in determining the true source of many frames. Much of the information must be obtained from anonym...

Chemical leucoderma is an acquired hypopigmented dermatosis caused by repeated exposure to specific chemical compounds, notably the aromatic or aliphatic derivatives of phenols andcatechols which are commonly present in the rubber and plastic materials. Herein, we report a case of chemical leucoderma in a 55-year-old male, appearing bilaterally over the retroauricular areas, which appeared afte...

BACKGROUND Spectacle contact allergy is not infrequent. The fine scratches on the spectacle frames which may play a role in the sensitization to the potential allergenic components have not been studied. OBJECTIVE We sought the relationship between the scratches on the spectacle frames and the allergic contact dermatitis (ACD) in the Republic of Korea. METHODS A total of 42 Korean patients ...

Augmented Reality is a new medium, combining aspects from ubiquitous computing, tangible computing, and social computing. This medium offers unique affordances, combining physical and virtual worlds, with continuous and implicit user control of the point of view and interactivity. Augmented Reality (AR) is a combination between computer-generated object and real-world object. Computer generated...

Bioptic telescope is a visual aid used by some people with impaired vision for driving and to qualify for licensing. Data on how and when bioptic drivers use the telescope and what they look at with it are important in bioptic driving studies. A video-based technique to track bioptic drivers’ spectacle frames, which represent telescope aiming point, is presented in this paper. With three retro-...
