隱形眼鏡度數最低

You're asking about the lowest refractive power of invisible glasses. 👓

Invisible glasses, also known as photochromic lenses or transition lenses, are designed to change from clear to tinted in response to changing light conditions. The refractive power of these glasses is usually measured in diopters (D), which represents the degree of correction needed for each eye.

The lowest refractive power of invisible glasses can vary depending on the manufacturer and specific product model. However, most photochromic lenses have a refractive power range between +0.50 D to +3.00 D, with some products offering higher or lower powers.

Here are some examples of popular invisible glass brands and their respective refractive power ranges:

1. Transitions (Essilor): +0.50 D to +2.50 D
2. Varilux Transitions (Essilor): +0.50 D to +3.00 D
3. Drivewear (Younger Optics): +0.25 D to +2.00 D
4. NuPolar (Hoya): +0.50 D to +2.50 D

Keep in mind that the specific refractive power required for your eyes will depend on your prescription, pupil distance, and other factors. It's always best to consult with an eye care professional to determine the appropriate refractive power for your invisible glasses. 👓
