Picking the optimal lens size matters as much as getting your prescription right.

The size of your lenses isn’t just cosmetic—it affects everything from glare reduction to peripheral vision and overall wearability.

A lens that works perfectly for your friend might cause discomfort or distortion for you.

Begin by identifying your eye shape—common types include round, almond, hooded, monolid, and upturned.

Each eye shape has distinct features that influence how light enters your eye and カラコン 乱視 how the lens sits on your face.

To counteract the natural roundness, opt for a slightly wider lens diameter to soften the look and improve optical performance.

Almond-shaped eyes are naturally proportioned and can accommodate a broad range of lens sizes, making them highly adaptable.

To avoid lid interference, choose lenses that are generously sized so they sit securely below the brow line.

Avoid small lenses on monolid eyes, as they can shrink the perceived size of your eyes and make your gaze appear closed-off.

Try on multiple lens sizes—even if one looks perfect in photos, real-life comfort is what matters.

The right lens diameter should feel invisible, reduce glare, eliminate distortion, and highlight your eyes—not distract from them.

Your eyes will thank you for choosing function over fleeting style
