美瞳基弧BC | 佩戴舒适度的关键密码

by CHUMINGMING 27 Mar 2025

宝子们,今天来聊聊美瞳挑选中超级重要但又容易被忽略的一个参数—— 基弧。

什么是美瞳基弧

美瞳的基弧(Base Curve,简称BC)是指镜片内表面的弧度,决定了镜片与眼球表面的贴合程度。基弧数值(如8.4mm、8.6mm)代表镜片的弯曲程度,数值越大,镜片越平坦;数值越小,镜片弧度越弯。

基弧对佩戴体验的影响

如果美瞳基弧选择不合适,佩戴美瞳时就会出现各种问题。基弧过大,镜片太平镜片会在眼球上滑动,导致视力不稳定,看东西模糊,而且还容易滑片,影响美观和舒适度。基弧过小镜片太弯,镜片会紧紧地贴在眼球上,阻碍眼球的正常代谢,眼睛会感觉很干涩、有异物感,长时间佩戴还可能对眼睛造成伤害。

选择佩戴基弧与眼球适配的美瞳,才能让镜片自然贴合眼球,活动度适中同时降低并发症风险

如何确定适合自己的基弧

1. 医院或专业机构测量:最准确的方法就是去医院的眼科或者专业的眼镜店,让医生或验光师使用专业的仪器测量你的角膜曲率,从而得出适合你的基弧数值。一般来说,角膜曲率对应的基弧有一个换算公式,不过专业人员会帮你搞定。

2. 参考过往佩戴经验:如果你之前佩戴过美瞳,并且感觉舒适度不错,可以查看之前购买的美瞳包装上标注的基弧数值,以此作为参考。但要注意,不同品牌的美瞳即使基弧数值相同,实际佩戴感受也可能有差异哦。

3. 多尝试不同基弧的美瞳。对于首次佩戴美瞳的人来说,都很难选择合适的美瞳基弧,但又会觉得去找验光师测量角膜曲率很麻烦。所以我建议先购买试用装,多尝试不同基弧的美瞳,找出最合适自己眼睛的美瞳基弧。美瞳挑选美瞳基弧的小建议

1. 新手选择适中基弧于刚开始佩戴美瞳的宝子,建议选择基弧在 8.6mm - 8.7mm 左右的产品,这个范围相对比较适中,适合大多数人的眼球。

2. 关注品牌说明:不同品牌的美瞳在基弧设计上可能会有一些差异,购买时一定要仔细查看产品介绍和说明,了解该品牌美瞳基弧的特点和适用人群。

3. 试戴感受很重要:如果有机会试戴,一定要认真感受一下佩戴后的舒适度。如果感觉镜片有明显的滑动或者过紧的感觉,那就说明这个基弧可能不适合你。

小贴士:即使基弧合适,每天佩戴时间也建议不超过8小时,并严格遵循清洁流程!

宝子们,选对美瞳基弧,才能让我们在拥有美丽双眸的同时,也能保证眼睛的健康和舒适。希望今天的分享对大家挑选美瞳有帮助呀

What is Lorem Ipsum? Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum. Why do we use it? It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
