The physical and optical characteristics of hydrophilic contact lens polymerized with addition of 2,5-difluoroaniline in the basic hydrogel contact lens material were evaluated, and in particular, the utility of 2,5-difluoroaniline as a UV-blocking material for ophthalmologic devices by measuring the UV transmittance was investigated. In this study, 2,5-difluoroaniline was added to the cross-linker EGDMA (ethylene glycol dimethacrylate), HEMA (2-hydroxyethyl methacrylate), NVP(N - vinly pyrrolidone), MA (methacrylic acid) and the initiator AIBN (azobisisobutyronitrile) in various concentrations. The results showed that water content, refractive index, contact angle and tensile strength were in the range of 37~38%, 1.434~1.438, 59~64° and 0.210~0.330 kgf independently. The transmittance of visible light decreased from 91% to 90% as the increase of 2,5-difluoroaniline. Also, the transmittance of UV-A and UV-B decreased from 86% to 79% and from 77% to 47%, independently. The material containing 2,5-difluoroaniline is expected to be used usefully as a material for UV-block hydrogel contact lens without affecting the water content and wettability.
