1. Age 45 years or more
2. Spectacle or soft contact lens wearer
3. Refraction: best sphere (corrected for back vertex distance) -6.00 Diopters (D) to +4.00 D; Astigmatism - 0.00 D to -0.75 D; Near addition for 40 cm; Medium Add: +1.50 D to +2.00 D; High Add: +2.25 D to +2.50 D
4. Best spectacle corrected visual acuity of 6/9 or better in each eye
5. Willingness to adhere to the instructions set forth in the clinical protocol
6. Signature of the subject Informed Consent form after review of Information to Participant document.

Exclusion Criteria:

1. Systemic or ocular allergies which might interfere with contact lens wear

3. Ocular disease which might interfere with contact lens wear (e.g. hypothesia, insufficient lacrimal secretion)
4. Use of medication which might interfere with contact lens wear
5. Active ocular infection
6. Use of ocular medication
7. Significant ocular anomaly
8. Presence of two or more corneal scars in either eye
9. Monovision contact lens wearers
10. Pregnancy or lactation
