There are a few ways to determine if your lenses are polarized:
1-Hold your glasses at an angle and look at a reflective surface, such as a mirror or a window. If the lenses are polarized, the reflection on the surface should appear darker or more distorted when viewed at different angles.
2-Hold your glasses up to a light source and look at the lenses from different angles. If the lenses are polarized, the amount of light that is able to pass through the lenses should change as you change the angle.
3-Look for a sticker or label on the lenses or frames that indicates that the lenses are polarized. Many manufacturers of polarized lenses include a sticker or label on the glasses to let customers know that the lenses are polarized.
4-Consult with an optician or eye doctor. If you are unsure whether your lenses are polarized, you can visit an optician or eye doctor who can evaluate your glasses and determine if the lenses are polarized.
Overall, the best way to determine if your lenses are polarized is to look for a sticker or label on the glasses or consult with an optician or eye doctor.
