Summary of Content

This module will develop an understanding of occupational visual requirements and eye protection regulations, lighting, colour vision and special optical appliances contact lenses to a level appropriate for a Dispensing Optician not registered to fit contact lenses.

Syllabus

Introduction to module and coursework details Special optical appliances Clinical decision making Real world clinical dispensing problem solving; dispensing the commercial world Light sources; types; efficacy; lighting terminology & units; inverse square and cosine laws Colour; Hue, luminosity, saturation Common occupational visual requirements Personal eye protection; limitations of spectacle eye protectors; principal British Standards; relevance of other BS; types of device; types of hazard Other occupational and recreational spectacles Colour vision: common tests and their use; types and names of common anomalies; significance; use of spectacles for colour vision deficiencies. Contact lenses: Corneal contour measurement; types of lens; materials; benefits and disadvantages; presbyopic correction; overview of therapeutic use; initial lens selection and fitting of RGP and soft contact lens patients; design, parameters and relationship to corneal contour; patient selection; hygiene; risk factors and advice; the adaptation process; significance of aftercare; contact lens insertion and removal by the patient or carer; insertion and removal by the Dispensing Optician.

Learning Outcomes

On completion of this module, students should be able to: Demonstrate communication skills.Demonstrate understanding of optical appliances beyond that of routine Dispensing practice.Demonstrate understanding of lighting and illumination.Use of an evidence-based approach to the supply of optical appliancesDemonstrate an understanding of colour and colour visionDemonstrate and understanding of contact lens practiceInsert and remove contact lenses

Teaching / Learning Strategy

Using concepts delivered within the module, students will develop their ability to communicate the module content to others, both their professional peers and the lay public. Module-specific on-line resources, conventional lectures, tutorials and laboratories will be used to develop a foundation of knowledge with directed study tasks expanding this to that expected of a Dispensing Optician
