When it comes to choosing the best glasses for men, it largely depends on personal style, face shape, and individual preferences. However, here are some popular styles that are commonly considered as versatile and suitable for many men:

1. Classic Wayfarer: This timeless style features a bold, square-shaped frame with thick rims. Wayfarer glasses are known for their iconic look and suit various face shapes.

2. Aviator: Originally designed for pilots, aviator glasses have a distinctive teardrop shape and thin metal frames. They offer a masculine and fashionable look that suits many face shapes.

3. Clubmaster: This style combines thick acetate or plastic rims on the top half with metal rims on the bottom half. Clubmaster glasses provide a sophisticated and retro-inspired look.

4. Rectangular or Square Frames: These frames have straight lines and angular edges, creating a modern and masculine appearance. They work well for men with round or oval face shapes, adding structure to their features.

5. Round Frames: Round glasses can add a vintage or intellectual vibe to your style. They are suitable for men with square or angular face shapes as they help soften the facial features.

Remember, it’s essential to try on different styles and shapes to see which ones complement your face shape and enhance your personal style. Additionally, consider factors such as frame materials, lens options (prescription or non-prescription, polarized, etc.), and proper fit to ensure comfort and functionality.
