Subject's systemic and ocular medical history must be considered normal in the opinion of the investigator at the Screening and Baseline visits. 4. Subject with Best corrected distance visual acuity (BCDVA) score ≥83 ETDRS letters, ≤ 0.00 LogMAR \[20/20 Snellen or 1.0 decimal fraction\] in each eye at the Screening and Baseline visits. 5. Normal anterior segment on external and slit lamp examination in both eyes at the Screening and Baseline visits. 6. Normal posterior segment on fundus ophthalmoscopic examination in both eyes at the Screening and Baseline visits. 7. Subject must be considered in good systemic health in the opinion of the investigator at the Screening and Baseline visits, as determined by: 1. Subject's body mass index is between 18.5 and 30.4 kg/m2 inclusive 2. A pre-study physical examination with no clinically significant abnormalities. 3. Vital signs within clinically acceptable ranges for the purposes of the study (sitting systolic blood pressure \[BP\] ≥ 90 mmHg and ≤ 150 mmHg; diastolic BP ≥ 50 mmHg and ≤ 95 mmHg; heart rate ≥ 40 and ≤ 100 beats per minute; oral body temperature ≥ 35.5°C and ≤ 37.5°C). 4. An ECG with no clinically significant abnormalities. 5. Pre-study clinical laboratory findings within normal range or not deemed clinically significant in the opinion of the investigator if outside of the normal range 8. Woman subject who meets the criteria for post-menopausal stage (post menopause is defined as the period following peri-menopause, i.e. postmenopausal after 12 months without a menstrual period and with a serum FSH value within the reference range for postmenopausal females at Screening) or permanently sterilised (e.g. tubal occlusion, hysterectomy, bilateral salpingectomy) or woman subject using oral, injected or implanted hormonal methods of contraception or with a double barrier methods of contraception: condom and occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/suppository. A female condom and a male condom should not be used together as friction between the two can result in either product failing. 9.
