PureVision 2 HD lenses: Incredible vision and helps reduce halos and glare.

In a global survey across seven countries, 3,800 vision-corrected patients stated vision is the most compelling feature when choosing eye-related products.1 Additionally, most patients are looking for more when it comes to their vision.1 

90% of lens wearers experiencing glare are interested in a solution that reduces glare2 

89% of lens wearers experiencing halos are interested in a solution that reduces halos2

Key Features & Benefits

Patients agree PureVision2 HD lenses deliver crisp, clear vision

77% of consumers agree PureVision2 HD lenses reduce halos and glare even in low light2

PureVision2 HD is designed to reduce spherical aberration

purevision2hd-spherical-abberation

PureVision2 HD contact lenses with High Definition Optics are designed to reduce spherical aberration across the entire power range.

Spherical aberration can be a barrier to high-quality vision in low light, resulting in blurred vision, halos and glare

In the general population, 0.15 μm of positive spherical aberration is typical for a 6 mm pupil3

2 Results from a 21 investigator, multi-site clinical study of PureVision2 HD and PureVision lenses. After 7 days of wear, subjects completed an online survey regarding lens performance. A total of 339 subjects completed the survey. Consumers rated the extent to which they agreed or disagreed with performance attributes that used a 6 point scale (1= strongly disagree and 6 = strongly agree)

4 The simulated retinal images of the "E" were generated using Vision Optics Laboratory software. The letter represents a 20/80 letter size viewed through a 6 mm pupil and an eye with and without no other aberration except for spherical aberration.

5 This simulated retinal image was created using Visual Optics Lab (Sarver and Associates, Inc., Carbondale, Illinois) and represent viewing the clock tower at a distance of approximately 800 feet over a 6 mm pupil. The image on the behind the lens graphic represents the effects of +0.15 um of spherical aberration. And the image in the lens graphic represents the retinal image in the absence of any aberrations.

6 PureVision data. In the core minus range, there is no clinically discernible difference between PureVision2 HD and PureVision. Twenty subjects were dilated to achieve a minimum of 6 mm pupil diameter. Baseline spherical aberration was measured using a Zywave™ aberrometer. PureVision and Night & Day (-1.00D and -5.00D) contact lenses were inserted into one eye in random order. The measurement of spherical aberration was repeated with the contact lens in place. A second cohort of 20 subjects compared PureVision to Acuvue Advance (-1.00D and -5.000D) contact lenses using the same protocol. PureVision spherical aberration measures were averaged between the 2 evaluations. A third cohort of 20 subjects compared Acuvue Oasys and 02Optix (-1.00D and -5.00D) contact lenses using the same protocol. Results are presented as the change from baseline compared to the spherical aberration reported for the general population.
