Start with fit and UV protection: pick a frame size that suits your face width and ensure the lenses provide adequate UV protection; the tortoise pattern should complement your skin tone and wardrobe.

Focus on frame size (lens width and bridge), material and weight, and lens options (UV protection or prescription compatibility) to fit your needs.

Look at frame material (acetate for color and pattern variety or metal for a lighter feel), nose bridge type, and finish (glossy or matte) to match your style and daily wear.

Choose a smaller frame width with a secure fit, prioritize a classic tortoise tone that pairs with many outfits, and check if prescription lenses can be accommodated if needed.
