Vision Testing

Vision TestingVision Testing is required where visual acuity is intrinsic to the function of the job.

Some jobs require a high degree of visual acuity, such as:

  • Fork Lift Driving
  • Visual Inspection
  • Any role requiring fine hand to eye co-ordination
  • Any role requiring depth perception (work under microscopes)
  • Visual Display Unit (Computer screen) working

 

Some jobs require good colour perception test to ensure that personnel are capable of distinguishing and differentiating colours where colour perception is required for product verification / inspection activities

  • Visual Inspection where colour is important
  • Any role dealing with colour coding or colour signals Engineering/Architectural Drafting
VDU Working

Regular breaks are required to rest the eyes and break from continuously using a single focus to avoid eyestrain and fatigue. Struggling with uncorrected vision will make eyestrain and eye fatigue worse and diminish performance.

There is no evidence that Display Screen Equipment (DSE) work causes any permanent damage to eyes. However, long spells of DSE work can lead to tired eyes, discomfort, temporary short-sightedness and headaches. DSE work is visually demanding, so it can make you aware of eyesight problems not noticed before (including changes in eyesight that happen with age)

The Law for VDU work and Vision Testing

The Safety, Health and Welfare at Work, (General Application) Regulations 2007, outlines the requirements in relation to Display Screen Equipment where the employee uses the VDU for continuous periods of more than one hour

The key requirements are to:

  • Provide training to employees in the use of workstations
  • Carry out an ergonomic risk assessment of employee workstations
  • Provide an appropriate eye and eyesight test


Every employee who uses a VDU as a significant part of normal work has a right to opt for an appropriate eye test and an eyesight test which must be made available and paid for by the employer.

On-Site Vision Testing

MedWise Mobile Medicals can provide an OH Nurse trained to use the keystone vision-screening machine.

The OH Nurse is trained and qualified to know when to refer employees who do not pass the eyesight tests at the screening level to a doctor or optometrist.

A vision Questionnaire is used to inquire about symptoms.

The Keystone Vision Screener is capable of testing several different parameters of vision in a short test time:

  • Acuity Right Eye – Far and Near
  • Acuity Left Eye – Far and Near
  • Acuity Binocular – At Far, Intermediate, Night and Near
  • Phoria (eye co-ordination) – Far and Near
  • Fusion – Far and Near
  • Stereopsis – Far and Near
  • Colour Perception – Severe and Mild
Colour Perception Testing

Should there be a requirement for more in-depth colour perception testing MedWise can carry out the Ishihara plate test

The Ishihara plate test consists of either 24 colour plates. It is the most widely used screening test for red-green deficiency and has been shown to be the most efficient test for this purpose. A very general indication of protan (Red-green colour blindness) and deutan defects is given in this test, but it is not, as such, a diagnostic test.

What is In Scope for MedWise Vision Testing?

MedWise will provide a simple 1-page vision health questionnaire to be completed by the employee.

Medwise will provide a competent person (RGN or OH Nurse) at our client’s site, trained in the use of the vision screening machine.

The Medwise Nurse will carry out the Vision tests using a Keystone vision screening instrument.

Abnormal results will be referred to the employee’s optician (or on occasion to their GP) using a letter of referral.

A vision test certificate will be issued to the employer.

An excel tracker file will be issued to the employer stating if a referral has been made.

MedWise provides a screening test service which screens out the employees who do not require a full optician assessment thus saving the employer time and money.
