Appraisal of professional aptitude
For some professions, good stereo vision is essential
Internationally, only some professions require a medical certificate of good stereo vision for employment. These include, but are not limited to, pilots, surgeons, firefighters, weapons-carrying government employees and various military occupations where accurate spatial perception is of great importance.
An employer may also require a certificate of good stereo vision for employment. In certain circumstances, an employer may also require a positive stereopsis as a condition of employment or may be required to obtain an opinion by the authorities.
In many other professions and certain occupations, it is valuable or even essential to have a good stereopsis in order to avoid accidents and harm, or to be able to practice that profession effectively and successfully.
The following list is incomplete and provides a rough overview of professions where good stereopsis is important: Turners, roofers, welders, blacksmiths, heavy current technicians, surgeons, crane operators, pilots, drone pilots, bus and tram drivers, locomotive drivers, shunters, forklift drivers, bowsers, excavator operators, professional divers, chimney sweeps, painters, grinders, dentists and dental technicians, precision mechanics, goldsmiths, gemstone cutters, restorers and art appraisers, forestry workers, loggers, arborists hunters, police officers, firefighters, hunters, mountain and ski guides, professional soldiers, lifeguards and many more.
Applicants of the Stereopsis tests to professional groups
Labour and education authorities as well as employers attach great importance to health and prevention of occupational diseases. Therefore, occupational candidates who meet the minimum health requirements for their respective occupations are usually promoted and trained. For standardised examinations of occupational groups, medical professionals, company doctors, school doctors, as well as ophthalmologists are called in.
A part of occupational eye examinations is nowadays performed by computer-assisted devices. However, these devices often do not provide reliable random-dot stereopsis testing.
The use of the Lang Stereopad® can help to determine the stereopic threshold or reliably detect non-existent or loss of stereopsis. The randomly presented figures of the Lang Stereopad® cannot be guessed by the subject.
Early career: stereo vision and aptitude
The importance of early detection of binocular vision disorders cannot be overemphasised to help young adults make the best career choices.
In many countries, a high proportion of young people still do not undergo stereopsis screening, resulting in them not being confronted with possible limitations due to their monocular vision until during their school career or when choosing a career.
Despite advances in the development of technical aids, many occupations even today do not allow access for people with impaired vision, especially stereopsis impairment. In such occupations, people with stereopsis impairments may reach their performance limits and have difficulty performing their jobs effectively and safely.
Voluntarily taking a stereopsis exam can be very helpful for optimal and successful career planning.
The Lang® Stereopsis Test I and II are ideally suited for this purpose. In the event of abnormalities, clarification should be obtained from an ophthalmologist and the stereopsis threshold determined, for example, with the Lang Stereopad®
