General Information About The Vision Tester

By Helga Stokes


The ability to see clearly enhances the quality of life of individuals and allows them to perform their daily activities effectively. For this reason, good vision has to be cherished, nurtured and guarded to prevent any potential risks. This can be achieved through frequent screenings and periodic visual exams. A vision tester helps to detect and treat eye problems as soon as they occur. It is advisable to seek medical assistance when any eye-related problem is experienced.

This equipment is very useful and performs various visual tests. Some of the common tests performed using testers include depth perception, muscle balance and visual acuity (horizontal and vertical phoria). It is widely used in aviation and the military to ensure the staff have a perfect visual ability. It is also used to test night vision particularly for those driving at night.

Modern forms of this device have several advanced features that enhance their efficiency. They are designed to accommodate both adults and children, either standing or seated. This is important to ensure patients are comfortable during testing process in order to obtain accurate results. It has a fluorescent light source which provides true color testing, replicates daylight conditions and improves slide illumination.

The lighting system is very efficient and consumes less power. This feature ensures no high voltages occur in the internal parts of the machine. It also protects the machine form the risks associated with high internal voltages which keeps in good working condition for a long period of time. It has a diffusor which provides clear backlighting. The tests are performed within a short time which saves time when multiple exams have to be performed.

They are easy to operate and convenient to use. This is made possible by the various features. They are light in weight, portable and compact and therefore the technicians can easily move them around and perform tests in different locations. It is possible to control them via a computer or remote controller. They are supplied with PC software that automates various tasks. Once installed, the software prompts the questions, records the response, prints and saves the results automatically.

Most of them have sensitive headrests that are removable. This is useful to ensure easy and proper positioning of the patient. The slides produce light as an indication that the forehead of the patient is in the right position. The slides should be removed and changed regularly to avoid infections. They may also be disinfected and reused.

The device is accompanied by a detailed manual to enable the technician to use it correctly and safely. It specifies the safety precautions, operating procedures and the specifications of the device. It is important to make proper use of the machine to avoid damaging it. It should also be maintained regularly to enhance the reliability of the results obtained. It has to be cleaned regularly using a suitable detergent.

A majority of eye problems can be cured if they are detected in their early stages. Routine visual screenings are necessary to detect these problems. Failure to treat visual defects increases the chances of developing blindness or impaired vision. Once they are detected and treated individuals are able to live more comfortably and productively. A vision tester is one of the most effective visual screening equipment used by eye care professionals.
