The Spark 4™ Measurement Experience

Taking measurements has never been easier, more precise, or as simple as it is now, thanks to Shamir’s Spark™ 4 measurement experience. With just one picture taken in a few seconds, an eyecare provider can get an automatic measurement of a patient’s PD. The remaining measurements can be marked later, with or without the patient.

Tip: Spark 4™ will position your store as advanced and innovative while also providing consultation time with a personal touch.

Combined, they detect and process 192 different facial landmarks. Another plus? Spark 4™ sees the patient’s pupils clearly even through sunglasses and various coatings.
