To report the symptoms and experiences associated with habitual hydrogel (Hyd) and silicone hydrogel (SiHy) contact lenses (CLs) among young adults and measure their association with age.
Questionnaire responses from 699 Hyd and 183 SiHy wearers were analyzed to test the association of age with features indicating struggle with CL wear. Prevalence by age was compared between groups with Pearson's chi-square and within groups with Spearman's correlation coefficient.
Hyd and SiHy groups were similar for sex and age distribution. Diagnosis of dry eye increased with age in the Hyd wearers from 10.6% to 21.1% (18-24 vs. 30-35 years), but was approximately 19% in the SiHy wearers across age. Adverse environments caused more discomfort with Hyd than SiHy lenses and Hyd wearers' discomfort increased with age (smoky (p=0.0001), dry air environments (p=0.002), after napping or sleeping (p=0.004). More Hyd wearers considered discontinuation of CL wear with age, from 4.6% to 14.2% (18-24 vs. 30-35 years, p<0.04), but the proportion remained steady at 9% across age for SiHy wearers (p=0.46).
From 18 to 35 years, hydrogel CL wearers reported increasing struggle with CL wear and more negative ratings compared to SiHy wearers. Older hydrogel CL wearers were also more likely to consider discontinuing CL wear compared with younger hydrogel or silicone hydrogel CL wearers in general. Young adult CL wearers should be routinely queried directly about specific aspects of CL wear in order to determine whether different lens types should be prescribed to avoid abandonment of CL wear.
报告年轻成年人中与习惯性水凝胶（Hyd）和硅水凝胶（SiHy）隐形眼镜（CL）相关的症状和体验，并测量它们与年龄的关联。
分析了699名Hyd佩戴者和183名SiHy佩戴者的问卷回复，以测试年龄与表明佩戴CL有困难的特征之间的关联。通过Pearson卡方检验比较组间年龄患病率，通过Spearman相关系数比较组内年龄患病率。
Hyd组和SiHy组在性别和年龄分布上相似。Hyd佩戴者中干眼症的诊断率随年龄增长从10.6%升至21.1%（18 - 24岁与30 - 35岁），但SiHy佩戴者在各年龄段的干眼症诊断率约为19%。与SiHy镜片相比，不良环境会使Hyd镜片佩戴者更不适，且Hyd佩戴者的不适感随年龄增加（烟雾环境（p = 0.0001）、干燥空气环境（p = 0.002）、午睡或睡眠后（p = 0.004））。随着年龄增长，更多Hyd佩戴者考虑停止佩戴CL，从4.6%增至14.2%（18 - 24岁与30 - 35岁，p < 0.04），但SiHy佩戴者在各年龄段的这一比例稳定在9%（p = 0.46）。
在18至35岁之间，水凝胶CL佩戴者报告佩戴CL的困难增加，且与SiHy佩戴者相比负面评价更多。总体而言，与年轻的水凝胶或硅水凝胶CL佩戴者相比，年长的水凝胶CL佩戴者也更有可能考虑停止佩戴CL。年轻的CL佩戴者应被直接常规询问CL佩戴的具体方面，以确定是否应开具不同类型的镜片以避免放弃CL佩戴。
