Essential vision testing equipment

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.

Halberg trial clips

Nearly every refraction stand carries Halberg trial clips, which act as trial frames for patients who already have glasses but need a new lens prescription. They fit over the patients’ current glasses so they can look through test lenses before leaving.

If you already know the patient’s distance is correct, these clips enable you to check the presbyopic addition.

You can also check with Halberg trial clips in various conditions – in any position, with any power, and with any plus or minus lenses during the retinoscopic testing.

Each Keeler Halberg trial clip has space for three additional lenses. Our clips have a protective rubber coating, preventing scratching on the patient’s lenses during the exam.

Color vision testing

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

  • Aging
  • Genetics
  • Certain medicines
  • Certain diseases
  • Exposure to chemicals

Ishihara color vision tests

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

Waggoner color vision testing

Waggoner offers traditional book-style tests and a software that makes it even easier to correctly examine and diagnose color deficiencies.

Since color blindness can be genetic, it is important to start screening at an early age. The Waggoner Color Vision Testing Made Easy (CVTME) was designed to help screen children as young as three years old. Using circles, stars, and/or squares makes it easy for children to read, and on most plates, children will be able to see at least one symbol even if they have a color deficiency.

The Waggoner PIP24 book is designed for both children and adults and has 24 pseudoisochromatic plates that screen for protan (red weak), deutan (green weak), and tritan (blue/yellow weak) deficiencies.

The Waggoner Computerized Color Vision Test (CCVT) software takes assessment to the next level. Designed for any one to use, CCVT is an all-in-one color vision testing suite containing all traditional tests, and more. The app’s self-scoring functionality eliminates manual work while ensuring a consistent test-taking experience every time.
