Our experienced optometrists perform both subjective and objective eye testing to minimize errors. We use a digital smart chart to measure visual activity, check the anterior segment of the eye with a slit lamp and ophthalmoscope, and use a retinoscope and auto-refractometer for objective refraction. For subjective refraction, we perform fogging and ICC as needed to determine exact spherical and cylindrical power. We also conduct a color vision test using the Ishihara chart and prescribe the best lenses based on the subject's profession and adaptation.
