•Control subjects:
•BCVA monocular ? 0.8 decimal (Snellen 6/7.5); age 6 - 58 years; no history of abnormal glare sensitivity, no suspected or confirmed eye disease in history and/or standard eye examination; agreement to participate in the study.
•Group 1: Achromatopsia (ACHM)
•Age 6 - 58 years, VA ? 0.1 decimal, LOCSIII Cataract grading < 2 or pseudophacic
•Group 2: Cone dystrophy (CD)
•Age 18 - 58 years, VA ? 0.1 decimal, LOCSIII Cataract grading < 2 or pseudophacic
•Group 3: Cataract (Cat)
•Age 18 - 58 years, VA ? 0.2 decimal, history of increased subjective glare sensitivity (Note: as prevalence of cataract with glare sensitivity below age 58 is very rare, age limit may need to be expanded to age 80 years for cataract patients and comparison of Visual Acuity Space is then made not with values of controls but only with the average standard BCVA value of these individuals)
•All groups: Agreement to participate in the study.

•Control subjects: Subjects who are incapable of giving consent. Subjects with conspicuous OCT results.
•Impaired vision group (Patients): Patients who are incapable of giving consent; having any eye disease other than achromatopsia, cone dystrophy, or cataract. Patients with conspicuous OCT results other than to be expected.
•All groups: Any (additional) eye disease or systemic disease or condition having influence upon the measurement according to the judgement of the investigator and study physician.
