By Helga Stokes


Good vision is an important asset that has to be constantly guarded and cherished throughout our entire lives. It enhances the ability of individuals to actively participate in their daily activities and lead a better quality life. To achieve and maintain the ability to see clearly individuals are required to get frequent screenings and visual exams. These procedures are made much easier by the vision tester which allows eye specialists to detect eye problems before they advance into serious cases. It is important to seek the services of medical experts.

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.

Technological advancement has led to the development of devices with additional features that are designed to enhance its efficiency. These machines can be used to both children and adults in standing or sitting position. They are very comfortable which ensures accurate readings are obtained without any difficulties. They are equipped with a fluorescent light source that enhances slide illumination, efficient color testing and replicates daylight conditions.

It has an efficient lighting system that consumes less power. This helps to avoid high voltages in the internal parts of the equipment. This is important to ensure the display slides are in good condition which helps to prolong the life of the equipment. It is regulated using a diffusor to provide clear and powerful backlighting. They allow medical professionals to perform multiple eye exams within a short period of time.

There are several features that make it easy to operate and convenient to use. It is compact, lightweight and portable which allow technicians to transport them easily as well as administer tests in different places. The remote control and PC control feature allow them to be controlled through a remote controller or a computer. There is PC software that is usually installed to prompt the test questions, register and tabulate the answers, print results and automatically save these results to an internal database.

It has an adjustable sensitive headrest. The headrest is adjusted to provide comfort to the patients and ensure the head is in perfect position. When the head is in perfect condition, the slides produce light and activate the elastometer. It can also be changed regularly or disinfected to prevent infections.

This device is usually accompanied by a manual containing essential information needed to operate it properly and safely. The document provides specifications, safety precautions and operating procedures. It should strictly be used for its intended purpose. Proper maintenance ensures accurate results are obtained every time it is used. This can be done by cleaning the cover and the panels on a regular basis using a neutral 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.
