Polymerization and Physical Property Assessment of Optical Lens Materials Containing Amide Group
Min Jae Lee, A Young Sung*
Water content, Oxygen permeability, N,N-dimethylacrylamide, N-methyl-N-vinylacetamide
The basic hydrogel lens with addition of N,N-dimethylacrylamide (DMA) and N-methyl-N-vinylacetamide (NMV) were manufactured. The optical and physical characteristics of ophthalmic lens were evaluated by measuring water content, oxygen permeability (Dk), refractive index and optical transmittance. The water content & oxygen permeability (Dk) of sample containing Ref., DMA group and NMV group was in the average of 34.48%, 35.54~49.19% & 13.003~18.468 × 10−11 (cm2/sec)(mlO2/ml×mmHg) and 36.28~44.95% & 12.270~16.883 × 10−11 (cm2/sec) (mlO2/ml×mmHg), respectively. And also, refractive index of the sample containing Ref., DMA group and NMV group was in the average of 1.4350, 1.4330~1.4131 and 1.4335~1.4195, respectively. Standard hydrogel monomer containing DMA and NMV was expected to be used usefully as a material for fabricating hydrophilic functional ophthalmic lens.
