2024年9月24日 · Gas permeable (GP) or rigid gas permeable (RGP) contact lenses offer many benefits compared to soft lenses. They also have some limitations. GP lenses are made of durable plastic that allows more oxygen and moisture to reach your eyes. This offers clearer vision and a lower risk of eye infections.

rgp跟普通的软性隐形眼镜不一样，不能自己购买，有毕竟严谨的配镜流程，要到眼科医院专门的验光医生进行验配和试戴。 这种眼镜开封后有效期是两年，但如果护理得当，没有什么不舒服，我个人觉得戴个两年半都行，之前知乎上看到过戴一副戴三年的都有。

RGP即Rigid Gas Permeable Contact Lens的英文缩写，中文涵义是硬性透氧性角膜接触镜。 RGP所含的硅、氟等聚合物，能够大大增加氧气的通过量。 与软性 隐形眼镜相比,既提高了透氧性,又保证材料的牢固性，并且具有良…

A rigid gas-permeable lens, also known as an RGP lens, GP lens, or colloquially, a hard contact lens, is a rigid contact lens made of oxygen-permeable polymers. Initially developed in the late 1970s, and through the 1980s and 1990s, they were an improvement over prior 'hard' lenses that restricted oxygen transmission to the eye.

2017年3月2日 · rgp根据不同的镜片品牌来选择一个试戴基弧（根据医生经验和检查结果），然后试戴，通过在裂隙灯下看配适来确定这个基弧是否合适。 如果只是看地形图、验光、曲率这些检查结果，不看试戴染色后的配适（包括镜片位置、活动度等）是绝对不能确定RGP的基弧 ...

硬性透氧性角膜接触镜，缩写为RGP（RGP即Rigid Gas Permeable Contact Lens的英文缩写），RGP所含的硅、氟等聚合物，能够大大增加氧气的通过量。 与软性隐形眼镜相比,既提高了透氧性,又保证材料的牢固性，并且具有良好的湿润性和抗沉淀性。

2020年10月10日 · 基弧是镜片光学区后表面曲率，由于光学区构成了镜片直径的大部分，所以在镜片的后表面与角膜的前表面之间产生的配戴动力学关系中，光学区曲率起关键作用。 基弧的选择根据角膜曲率计读数或称K读数。 通常，中央部匹配验配选择较K值平坦的基弧，直径大（>9.0mm）；中央部稍充盈验配基弧角K值稍陡，直径小（<9.0mm）。 这里举一个示例来说明选择基弧的方法。 我们读出角膜平K值为7.94mm，最后选择试戴片可为7.95mm或者8.00mm。 …

2024年11月30日 · Rigid Gas Permeable lenses, sometimes called "hard lenses," are made from a firm, durable plastic material. Unlike soft lenses, which are made mostly of water, RGP lenses hold their shape when you take them out of your eye. Despite their firmness, they allow oxygen to pass through them, which is crucial for maintaining the health of the eye.
