Short-term Study of Myday Sphere and Myday Toric Lenses in Existing Spherical Soft Contact Lenses Wearers With Low Astigmatism (Pacific)
The primary objective of the study is to evaluate and compare the performance of two soft contact lens.
• At least 17 years and no more than 42 years of age.
• Have read and signed the study consent form.
• Are willing and able to follow instructions and maintain the appointment schedule.
• Are habitual wearer of spherical soft contact lenses (not toric or multifocal design), any brand and any replacement frequency.
• Are willing to wear the study contact lenses for 6 days a week while in this study and on three days (day 1, Day 7 and Day 13) for at least 12 hours.
• Are willing to provide a contact email and telephone number and to use a device that allows them to respond to a short online questionnaire every 3 hours on days 1, 7 and 13 of each lens arm, while wearing one of the 2 study lenses.
• Are non-presbyopic i.e. no requirement for a reading addition for routine daily tasks (self report).
• Have astigmatism of either -0.50, -0.75, -1.00 or -1.25 DC in each eye by subjective sphero-cylindrical refraction.
• Achieves at least 0.10 LogMAR in each eye by subjective sphero-cylindrical refraction.
⁃ Can be fit with available study contact lens powers of between +6.00 to -10.00 DS.
⁃ Demonstrate an acceptable fit with the study contact lenses.
