Abstract Purpose : This study analyzed physical properties using 1,6-Hexanediol diacrylate (HDDA) as an additive to improve functionality of hydrogel lens such as durability. It was checked whether HDDA can be applied as a crosslinking agent in place of ethylene glycol dimethacrylate (EGDMA). Methods : Polymerization used thermal polymerization and photopolymerization methods, and HDDA was added to each polymerization method at a ratio of 1∼20%. Optical and physical characteristics of the manufactured lens were evaluated by measuring spectral transmittance, refractive index, water content, tensile strength, contact angle, and AFM. Results : Regardless of the polymerization method, the tensile strength ranged from 0.232~0.408 kgf/mm2 in thermal polymerization and from 0.146~0.429 kgf/mm2 depending on the addition ratio of HDDA. In addition, as a result of using HDDA instead of EGDMA, it was confirmed that the physical characteristics of the lens were similar to that of EGDMA, and in the case of tensile strength, HDDA was much improved. Conclusion : HDDA has been shown to be effective in improving the functionality of hydrogel lens and to improve stability and durability. In addition, it is believed that it can be used in various ways as an ophthalmic material as well as a photopolymerization crosslinking agent.
