The decision between wearing prescription sunglasses or contact lenses depends on your personal preferences and lifestyle. If you prefer the convenience of not having to switch between glasses and sunglasses, contact lenses may be a better option. However, if you have sensitive eyes or prefer not to wear contact lenses, prescription sunglasses can provide protection from the sun while correcting your vision. It's best to consult with your eye care provider to determine which option is most suitable for your needs. **

Yes, Ahura Mazda and Angra Mainyu can be seen as metaphors for the inner struggle in every being. Ahura Mazda represents the forces of good, light, and truth, while Angra Mainyu represents the forces of evil, darkness, and falsehood. This duality mirrors the internal conflict between our own positive and negative tendencies, highlighting the eternal struggle between right and wrong within each individual. By understanding and balancing these opposing forces within ourselves, we can strive towards personal growth and spiritual enlightenment. **

Ahura Mazda and Angra Mainyu are central figures in Zoroastrianism, representing the forces of good and evil, respectively. While they are not explicitly a metaphor for the inner struggle in every living being, their eternal conflict can be seen as symbolic of the universal struggle between good and evil that exists within individuals. The concept of duality and the constant battle between positive and negative forces is a common theme in many religious and philosophical traditions, and can be interpreted as reflecting the inner struggles that people face in making moral and ethical choices. Therefore, one could argue that Ahura Mazda and Angra Mainyu can serve as a metaphor for the inner struggle within every living being. **

Optical glasses can be converted into sunglasses by adding tinted lenses to the frames. These tinted lenses can be either prescription or non-prescription, depending on the wearer's needs.

Polarized lenses in sunglasses are designed to reduce glare from surfaces such as water, snow, and roads. They contain a special filter that blocks intense reflected light, allowing only vertical light to pass through.

Polarized lenses are also effective in reducing the harmful effects of UV rays, providing added protection for the eyes. **

Each type of contact lens has its own advantages and considerations, such as cost, convenience, and maintenance requirements. **
