Purpose: To evaluate and analyze the quality of Korean prescription lenses according to international standards.
Methods: We measured the refractive power, the thickness at optical center and the transmittance, and then made a comparative analysis them with foreign brand products according to international standards.
Results: Most of Korean products had good qualities on the refractive power and transmittance, even if there was out of tolerance in a case of korean products.
Conclusions: To ensure a higher preference of Korean products in the home and abroad marketplace, a high-powered quality control and marketing strategy are necessary to domestic lens manufacturers.
