8 out of 19 cases of acute or chronic hepatitis, with positive hepatitis B surface antigen (HBsAg) had HBsAg-positive tears. In 25 healthy HBsAg carriers, no HBsAg was found in the tears. The HBsAg concentration in the tears of hepatitis patients was less than 1% of the HBsAg in their blood. Contact lenses (soft hydrophilic, silicone) experimentally contaminated with HBsAg were practically free of it after the usual cleaning and washing with a commercial contact lens cleaning fluid. No adsorption of HBsAg was found on hydrophilic soft lenses; a minimal adsorption on silicone lenses could not be entirely excluded, but practically it was without any importance. In 14 samples of 79 storage fluids of a contact lens fitting set HBsAg was found. The cause of this contamination is not clear.
19例急性或慢性乙型肝炎表面抗原（HBsAg）阳性患者中，有8例泪液HBsAg阳性。25例健康HBsAg携带者泪液中未检测到HBsAg。肝炎患者泪液中的HBsAg浓度低于其血液中HBsAg浓度的1%。用市售隐形眼镜清洁液对实验性污染HBsAg的隐形眼镜（软性亲水、硅水凝胶）进行常规清洁和冲洗后，其上的HBsAg基本清除。未发现HBsAg吸附于亲水性软性隐形眼镜；硅水凝胶镜片上有极少量吸附不能完全排除，但实际上无任何影响。在79份隐形眼镜试戴套装储存液样本中，有14份检测到HBsAg。这种污染的原因尚不清楚。
