隱形眼鏡弧度最大

You're referring to the maximum curvature of invisible glasses! 😄

Invisible glasses, also known as progressive lenses or no-line bifocal lenses, are designed to provide a seamless transition between different powers without visible lines or segmentations. The maximum curvature of invisible glasses depends on various factors, including:

1. Frame style and material: Thicker frames with more robust materials can accommodate higher curvatures.
2. Lens thickness: Thin lenses can be more challenging to shape to high curvatures due to manufacturing limitations.
3. Power range: Higher power ranges require more complex lens designs and may have limited curvature options.

Typically, the maximum curvature for invisible glasses is around 8-10 diopters (D), which is equivalent to a moderate to strong prescription. However, some manufacturers can produce lenses with higher curvatures up to 12-14 D or even higher, depending on the specific design and material used.

To give you a better idea, here are some general guidelines for invisible glasses curvature:

• Low power: 1-3 D ( minimal to moderate curvature)
• Medium power: 4-6 D (moderate to strong curvature)
• High power: 7-10 D (strong to very strong curvature)
• Very high power: 11-14 D (extremely strong curvature)

Please note that these are general guidelines, and the actual maximum curvature of invisible glasses may vary depending on the manufacturer, frame style, and other factors. It's always best to consult with an eye care professional or a reputable online retailer for more information on available curvatures and recommendations for your specific needs. 👓
