SpotChecks™ Contrast Sensitivity Test

SpotChecks™ is a contrast sensitivity test designed to support functional vision assessment through simple, affordable, and repeatable testing. Developed by vision science pioneer Dr. John Robson ScD FRS., SpotChecks enables clinicians, researchers, and patients to monitor visual function changes that may not be detected through standard visual acuity testing alone.

Designed for both clinical and home use, SpotChecks provides an accessible method for measuring contrast sensitivity and tracking visual performance over time.

Contrast Sensitivity Testing Reveals More Than Visual Acuity

Visual acuity testing measures the ability to identify high-contrast targets, but many patients experience visual difficulties despite achieving normal acuity results.

Contrast sensitivity testing helps evaluate how patients perform in real-world visual environments involving:

• Low lighting conditions
• Night driving
• Glare sensitivity
• Reading under reduced contrast
• Face and object recognition
• Everyday visual function tasks

By measuring visual performance across varying contrast levels, clinicians can gain a more complete understanding of functional vision.

Functional Vision Assessment Beyond Standard Eye Charts

Many visual conditions can impact contrast sensitivity before significant changes appear on standard visual acuity tests.

SpotChecks may be utilized when monitoring patients with:

• Cataracts
• Glaucoma
• Macular degeneration
• Diabetic eye disease
• Multiple sclerosis
• Neurological disorders
• Low vision conditions
• Vision rehabilitation programs

Contrast sensitivity assessment provides valuable insight into visual function that traditional eye charts may not fully capture.

Frequently Asked Questions

What is the SpotChecks™ contrast sensitivity test?

SpotChecks™ is a self-administered contrast sensitivity test designed to measure functional vision and monitor visual performance changes over time.

What does contrast sensitivity testing measure?

Contrast sensitivity testing evaluates a person's ability to detect subtle differences between objects and their background, providing insight into real-world visual performance.

How is SpotChecks different from a standard eye chart?

Traditional eye charts primarily measure high-contrast visual acuity. SpotChecks evaluates contrast sensitivity, which may reveal visual function changes not detected by acuity testing alone.

Can SpotChecks be used at home?

Yes. SpotChecks was specifically designed to support patient self-monitoring and home-based visual function assessment.

What conditions may affect contrast sensitivity?

Contrast sensitivity may be affected by cataracts, glaucoma, macular degeneration, diabetic eye disease, multiple sclerosis, neurological disorders, and low vision conditions.

Who uses SpotChecks?

SpotChecks is utilized by ophthalmologists, optometrists, researchers, vision rehabilitation specialists, educators, and patients participating in visual monitoring programs.

Why is contrast sensitivity important?

Contrast sensitivity provides valuable information about how patients function in everyday visual environments and may identify visual performance changes before they appear on standard acuity tests.
