REVIEW
Vivek K Gupta, Veer B Gupta
Rapid advances in ocular diagnostic approaches and emerging links of pathological changes in the eye with systemic disorders have widened the scope of optometry as the front line of eye health care. Expanding professional requirements stipulate that optometry students get a meticulous training in relevant information and communication technologies (ICT) and various bioinformatics and health informatics software to meet current and future challenges. Greater incorporation of ICT approaches in optometry education can facilitate increased student engagement in shared learning experiences and improve collaborative learning...

BACKGROUND: Extensive literature in ergonomics and optometry has indicated that computer use is closely associated with visual problems. Computer-Aided Design (CAD) requires a substantial effort on behalf of the visual system. The manifestations of visual fatigue phenomena may affect the working behavior and the human-system interaction. OBJECTIVE: The aim of this survey is to identify the normal working conditions and how the eventual visual fatigue phenomena are able to influence the working behavior of CAD users...

Visual impairments are common after traumatic brain injury (TBI) and negatively affect quality of life. We describe a 39-year-old woman with a severe TBI who was evaluated by the inpatient optometry and vision rehabilitation service with findings of complete right homonymous hemianopia and right cranial nerve III palsy with 30-degree right exotropia (eye turn out) and complete right ptosis (eyelid will not open). The 30-degree exotropia advantageously generated 30 degrees of right visual field expansion when the right ptosis was treated with a magnetic levator prosthesis, which restores eyelid opening...

INTRODUCTION: Hearing and vision loss among long-term care (LTC) residents with dementia frequently goes unnoticed and untreated. Despite negative consequences for these residents, there is little information available about their sensory abilities and care assessments and practices seldom take these abilities or accessibility needs into account. Without adequate knowledge regarding such sensory loss, it is difficult for LTC staff to determine the level of an individual's residual basic competence for communication and independent functioning...

Min Zhang, Songjing Li
In this work, liquid colour-changing lenses for vision protection, camouflage and optical filtering are developed by circulating colour liquids through microfluidic channels on the lenses manually. Soft lithography technology is applied to fabricate the silicone liquid colour-changing layers with microfluidic channels on the lenses instead of mechanical machining. To increase the hardness and abrasion resistance of the silicone colour-changing layers on the lenses, proper fabrication parameters such as 6:1 (mass ration) mixing proportion and 100 °C curing temperature for 2 h are approved for better soft lithography process of the lenses...

James R Auvil
Appreciation for combat eye protection steadily increased following World War II. Products derived from experiences in World War I, World War II, Korea, Vietnam, and the Iran/Iraq war drove technical improvements throughout the 1980s and 1990s. Dismal wear compliance prior to 2004 indicates Soldiers and their leaders did not appreciate these improvements and found little value in the bulky, ugly, and uncomfortable products. In 2003, the 10th Mountain Division requested enhanced eye protection. Program Executive Office Soldier, the optometry consultant to the Army Surgeon General, members of the Tri-Service Vision Conservation and Readiness Program, and other subject matter experts selected and tested commercial off-the-shelf eye protection against military ballistic impact standards...

BACKGROUND: Optometry students are taught the process of subjective refraction through lectures and laboratory-based practicals before progressing to supervised clinical practice. Simulated leaning environments (SLEs) form part of an emerging technology used in a range of health disciplines; however, there is limited evidence regarding the effectiveness of clinical simulators as educational tools. METHODS: Forty optometry students (20 fourth year and 20 fifth year) were assessed twice by a qualified optometrist (two examinations separated by four to eight weeks), while completing a monocular non-cycloplegic subjective refraction on the same patient with an unknown refractive error, simulated using contact lenses...

In recent years, new technologies and ideas of modern ophthalmology and optometry have emerged. Based on the wavefront technology and its derivatives, the traditional concepts of refractive errors and vision correction have been redefined and supplemented. Human optical quality can be evaluated effectively and objectively. Moreover, the studies about the wavefront vision correction have shown preferable vision correction results. Application of these modern methods of wavefront refraction and correction offers important opportunities for better optical quality and visual performance in corneal refractive surgery...
