Table 1.

A short description of the purpose of each of the experimental sessions and the measurements taken during the session. All rankings were made without ties.

Experimental session	Purpose	Measurements taken (units)
Naturalistic task and phoria	Identify symptoms during everyday tasks	Physical symptoms: headache, dizziness, and nausea (Likert 1–5)
		Perceptual symptoms: objects distorted, blurry vision, etc. (Likert 1–5)
		Eye strain (Likert 1–5) Phoria (prism diopters; Δ)
		Discomfort ranking
		“Would you wear the lenses on a regular basis?” (Yes/No)
Oscillopsia	Investigate perceived motion associated with head movement	Afterimage motion range (degrees) Perceived motion (Likert scale 1–5) Motion ranking “Would you wear the lenses on a regular basis?” (Yes/No)
Controlled head and eye movement	Identify which head and eye movements are responsible for physical discomfort in naturalistic task	Physical symptoms: headache, dizziness, and nausea (Likert 1–5) Discomfort ranking “Would you wear the lenses on a regular basis?” (Yes/No)
