OBJECTIVE To verify age of first ophthalmic evaluation and optical prescription along with present optical correction among ophthalmologists of different age groups. METHODS A cross-sectional study was conducted with a nonprobabilistic sample (n = 578) of ophthalmologists and resident physicians using a self-administered questionnaire. RESULTS The first ophthalmologic exam was undergone bef...

Although the trend in manufacturing has been towards centralization to leverage economies of scale, the recent rapid technical development of open-source 3-D printers enables low-cost distributed bespoke production. This paper explores the potential advantages of a distributed manufacturing model of high-value products by investigating the application of 3-D printing to self-refraction eyeglass...

A number of studies have demonstrated that infrared (IR) imagery offers a promising alternative to visible imagery due to it’s insensitive to variations in face appearance caused by illumination changes. IR, however, has other limitations including that it is opaque to glass. The emphasis in this study is on examining the sensitivity of IR imagery to facial occlusion caused by eyeglasses. Our e...

Background and Aim: Various methods have been used to reduce the patient's anxiety during dental treatment. In recent years, there has been an increase in behavioral research regarding virtual reality (VR) and virtual world as it offers more immersive images and works by blocking out real-world stimuli (visual, auditory or both). This study aimed at assessing the impact of VR on working conditi...

While for the evaluation of robustness of eye tracking algorithms the use of real-world data is essential, there are many applications where simulated, synthetic eye images are of advantage. They can generate labelled ground-truth data for appearance based gaze estimation algorithms or enable the development of model based gaze estimation techniques by showing the influence on gaze estimation e...

Ocular infections have been associated with bacterial contamination of eyeglasses. This study assessed contaminants the eyeglasses staff and students Babcock University, Ilishan-Remo, Ogun State, Nigeria. A total 100 participants comprising 33 males 67 females (aged 16-76 years) were recruited for after obtained written informed consents. structured questionnaire was used to collect demographic...

PURPOSE To determine prescribing practices of pediatric ophthalmologists for astigmatism and astigmatic anisometropia in infants and young children. METHODS A survey was sent to the 700 North American AAPOS members listed in the 2004 web site directory. RESULTS A total of 412/700 surveys (59%) were returned. The level of astigmatism at which pediatric ophthalmologists prescribe eyeglasses f...
