Effect of Blue Light Filtration on Visual Performance

Effect of Blue Light Filtration on Visual Performance

The purpose of this study is to evaluate photostress recovery with blue light filter clip-on glasses among pseudophakes [ie, subjects in which the natural lens of the eye has been replaced with an artificial lens (intraocular lens) during cataract surgery]. This study will enroll subjects previously implanted with no blue light filter intraocular lenses (IOLs) for at least 3 months.

Inclusion Criteria:

• Cataract surgery in both eyes with no blue light filtering intraocular lenses for at least 3 months;
• Good ocular health;
• 20/40 or better vision with best correction in both eyes;
• Willing to provide voluntary consent and sign informed consent form;
• Able to competently perform testing;
• Other protocol-defined inclusion criteria may apply.

Exclusion Criteria:

• Ocular pathology, degeneration, or media opacity (cloudiness) that could impact study measurements;
• Other protocol-defined exclusion criteria may apply.
