Visual Acuity Screener

Current Standard of Care for Vision Screening of Young Children

There is consensus among healthcare providers that the earlier a vision problem is diagnosed and treated, the less the potential negative impact on the child’s development, delayed reading and poor overall school performance.

66% are not screened before starting school

33% of vision impairments are missed

60% have vision problems that are missed 

80% of impairments are preventable with early diagnosis

 


VIFANT Visual Acuity Screener

Our visual acuity screening method uses the principles of the OptoKinetic Nystagmus (OKN) reflex to tell whether a patient’s eyes can follow a moving target. VIFANT can objectively measure vision acuity in patients as young as 6 months of age, even without verbal communication between the tester and the patient.

No Extra Hardware to Buy

Leveraging an off-the-shelf tablet, VIFANT is able to perform this evaluation without requiring any specialized hardware, expensive cameras, or equipment.

Ease of Use

Primary Care Physicians and their staff can perform visual acuity testing of young children using just an iPad and the VIFANT Vision Acuity Screener app.

Speed

With young children, every minute counts for a speedy patient experience. Screening only takes 2 minutes.


What is OKN?

OKN, or optokinetic nystagmus, is the reflexive eye movement response to moving targets: eyes will follow moving targets. It is a natural behavior of the eyes.

When a target leaves the visible field, the eye’s ability to make corrective adjustments is a sign of a normally functioning visual system.

By using OKN, no verbal communication is needed between the tester and the patient; therefore, the visual acuity testing can be extended to pre-verbal and non-verbal patients.
