PureVision2 HD Halos and Glares

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

BigBen 


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

retinal image

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.
