1. Superior Binocular Accuracy

Plusoptix S20 measures both eyes simultaneously, just like how vision works in real life.

✔ More reliable detection of:

• Anisometropia (unequal prescription between eyes)
• Amblyopia risk factors
• Binocular refractive errors

Benefit: Fewer false positives and more confidence in screening results.

In contrast, the Spot which can miss subtle binocular issues.

 2. Built for Pediatrics — Doesn’t Feel Scary

The S20 uses engaging fixation targets that capture attention easily — even from toddlers and uncooperative children.

✔ Longer working distance (~1 m / 3 ft)
✔ Friendly prompts and visuals
✔ Fewer attempts required to get a reading

Benefit: Higher first-attempt success rate and less stress for patients and staff.

Spot’s closer range and handheld posture can feel more invasive to young kids.

 3. Faster Throughput — Real Time Results

The S20 delivers results quickly and efficiently.

✔ Instant automated interpretation
✔ Clear Pass/Refer indicators
✔ Reduced operator training time

This speeds up high-volume screenings — ideal for busy pediatric clinics, school screenings, and community vision programs.

 4. Clinically Validated Against Established Guidelines

Plusoptix technologies align closely with AAP and AAPOS vision screening recommendations.

✔ Strong evidence in detecting amblyopia risk
✔ Reduced over-referral rates
✔ Clinician confidence backed by published performance

Spot is effective, but several studies show Plusoptix devices often outperform handheld screeners in specificity and sensitivity.

 5. Less Operator-Dependent

Plusoptix S20’s firmware and optics reduce user variability.

✔ Easier to use consistently, even for minimally trained staff
✔ More standardized results across screeners
✔ Less impact from operator experience

With Spot, handheld operation means readings depend more on steadiness, angle, and distance — increasing variability.

 6. Better Screening Results in Challenging Populations

Children with developmental delays, sensory issues, or low cooperation are no match for the S20’s:

✔ Engaging targets
✔ Built-in prompts and feedback
✔ Longer, comfortable screening distance

The Spot, with its closer and more direct method, can yield more retries and frustration
