| FVA (log MAR) | 0.01±0.03 (0.00–0.03) | 0.00±0.02 (−0.01–0.01) | 0.4224 |
| VMR (%) | 0.98±0.03 (0.96–0.99) | 0.97±0.04(0.94–0.99) | 0.4537 |
| Blink Rate (frequency/minute) | 17.90±10.12 (11.62–24.17) | 21.20±6.92 (16.91–25.48) | 0.2472 |
Notes: The data are expressed as the average±deviation (95% confidence interval). Compared with narafilcon A, the CA differ significantly in the samfilcon A.
