Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. They understand their rights as a research subject and are willing and able to sign a Statement of Informed Consent.
3. They habitually use soft contact lenses (multifocal soft contact lenses, sphere lenses for monovision, sphere lenses for distance vision correction and spectacles for near vision correction,) and have done so for at least the past three months.
4. They have a minimum reading add of +0.75DS (based on their spectacle refraction)
5. They have spherical equivalent refractive error between +6.00 to -10.00DS at the corneal plane and refractive astigmatism of no greater than -0.75DC in each eye.
6. They are able to achieve distance HCVA of +0.10 logMAR or better in each eye.
Exclusion Criteria
2. They have a systemic disorder which would normally contra-indicate contact lens wear.
3. They are aphakic.
4. They have had corneal refractive surgery.
5. They have any corneal distortion resulting from previous hard or rigid lens wear or have keratoconus.
