Essential Vision Testing Equipment for Optometrists

Many eye patients will only get a check-up once in a long while, so ensuring you can provide excellent service every time is vital.

High-quality vision testing equipment is essential in assessing your patients’ vision as accurately as possible and being the best in the optometry field. With sight testing and optometry equipment from Keeler, you can ensure your prescriptions and prognosis are fully accurate.

Let’s take a look at some essential vision testing equipment.

Amsler chart manual

Our Amsler chart manual is a widely-approved standard piece of equipment in the optometry field. First invented in the early half of the 20th century, these grid charts are among the most recognised and influential eye exams worldwide.

This set includes charts for an exam and instructions on how to interpret those examination results.

The easy-to-use charts help with early detection of changes in the macula and fovea ocular regions. A patient only needs six responses during the exam to provide information that will lead you to a complete diagnosis of critical vision disturbances.

These may include:

Scotoma
Metamorphopsia
Maculopathy
Plus, many others

Maddox Wing test

Keeler’s Maddox Wing is an excellent piece of vision testing equipment for measuring heterophorias and heterotopias. It’s a go-to for many ophthalmologists, especially when patients describe double vision with no obvious cause. It also has numerous other uses.

This hand-held device provides quick and efficient measurements for various eye conditions
Its red vertical scale measures heterophoria
The white horizontal scale measures esophoria and exophoria
You can also measure cyclophoria by moving the red arrow pointer to be parallel with the white scale

The Maddox Wing testing tool causes no discomfort, takes little time to learn and use, and produces valuable measurements for eye patients of all ages, including children.

Trial lens sets and frames

Nearly every practice has a set of trial lenses, which act as trial glasses for patients who already have glasses but need a new lens prescription. Although this is considered an older technology, this classic technique is an important part of examining low vision patients. Some benefits of using trial frames are:

Allows for low vision patients to move their heads and eyes around as they would on a daily basis, improving testing accuracy
Lenses have larger refractive increments so low vision patients can tell the difference.
It enhances accurate vertex distance, which is useful for high refractive error patients.

Colour vision testing

According to Colour Blind Awareness, colour blindness is more common in men affecting about 1 in 12 men, and only 1 in 200 women. The majority of people with colour blindness have inherited the condition, but it can also be caused by:

Aging
Genetics
Certain medicines
Certain diseases
Exposure to chemicals

Ishihara colour vision tests

Having the right colour vision test is important for correctly diagnosing patients. Keeler Ishihara tests come as books, which contain either 24 or 38 pseudoisochromatic plates containing different coloured dots to check for colour blindness.

Why invest in high-quality essential vision testing equipment?

Purchasing high-quality sight testing equipment should be a no-brainer for any eye specialist.

Good equipment can not only improve the accuracy of your test results and prescriptions, but it can also help make the whole process more comfortable for your patients.
