Basic features in all devices:

• Simultaneous measurement of both eyes

• 1 meter (3.3 feet) working distance ±5cm (±2 in)

• 0.5 second acquisition time

• Full refraction recording, i.e. sphere, cylinder, and axis

• Interpupillary distance, and pupil size readings

• Eye alignment, and asymmetry of gaze assessment

Optimal illumination

• Plusoptix devices use a unique 54 LED strong flashlight.
  This optimally illuminates the pupil

Accurate measurement algorithm

• Numerous peer-reviewed clinical studies validate that Plusoptix devices consistently deliver highly accurate refraction recordings.
• Plusoptix devices take measurements automatically, when measurement prerequisites (i.e. distance, pupil size and eye alignment) are being met. Measurements are always accurate. There is no need to repeat it.

High-resolution camera

• The quality of a Plusoptix photo is not limited to simply derive refractive recordings. It enables an experienced user to identify media opacities within the pupil.
