The EpiGlare Tester will identify visual disability resulting from the glare experienced by subjects with cataracts in the glare-induced change in best spectacle corrected visual acuity (BSCVA).

Inclusion Criteria:

2. Have been evaluated by an opthalmologist and have a lens determination of either Normal or Cataract in each eye based on slit lamp examination.

   2. Cataract = lens opacity of 2+ or greater

3. Have written informed consent as required by the site's IRB and received a copy.

4. Are willing and able to comply with testing according to the Investigator.

Exclusion Criteria:

1. Best corrected visual acuity is worse than 20/60 in either eye
2. Have occular pathology including corneal or macular disease or advanced glaucoma
3. Have cognitive dysfunction which limits the ability to cooperate with testing.
4. Have presence or history of any other condition or finding or concomitant medication that, in the investigator's opinion, makes the subject unsuitable as a candidate for EpiGlare or study participation or may confound the outcome of the study.

Inclusion Criteria:

clear lenses OU cataracts OU willing to comply with testing

Exclusion Criteria:

BCVA < 20/63 either eye ocular pathology (ie corneal, macular disease, advanced glaucoma) cognitive dysfunction other conditions that in the investigators opinion made the subject unsuitable candidate
