Clip-on sunglasses attach to regular eyeglasses through magnets, clips, or hinges, allowing wearers to easily transition between indoor and outdoor settings without switching glasses. More affordable than prescription sunglasses, they come in various styles and tints to match different frames. This practical accessory provides convenient sun protection for eyeglass wearers.

Match frame shape/size for proper fit. Choose attachment type (magnetic, clip, flip-up) per preference. Select appropriate tint for activities—darker for bright sun, amber for low light, polarized for driving/water. Verify 100% UV protection. Ensure durable construction and lightweight design to prevent frame stress.

Attaching clip-on sunglasses varies by design: magnetic types simply align with the metal frame of your glasses; clip-style versions require gently squeezing the clips to open them, placing over your frames, then releasing; flip-ups attach at the top bridge and remain hinged. For removal, magnetic clip-ons pull away with gentle pressure; clip styles need careful squeezing to release without scratching lenses; flip-ups stay attached but can be flipped up when not needed. Always handle clip-ons by their frames rather than lenses to prevent smudges and scratches.

Quality clip-on sunglasses typically provide UV protection, with most reputable brands offering 100% UV-A and UV-B blocking capabilities. However, protection levels can vary significantly between products, so it's essential to check the manufacturer's specifications before purchasing. Look for labels indicating "UV400" or "100% UV protection" to ensure adequate shielding from harmful ultraviolet radiation. While tint darkness relates to visible light reduction and comfort, it doesn't necessarily indicate UV protection level, so even lighter-tinted clip-ons can offer complete UV defense if properly manufactured.

Clip-on sunglasses typically work with plastic frames, but compatibility depends on frame design, thickness, and clip mechanism. Standard clips and universal designs fit most plastic frames, while magnetic clips require compatible frames. Consult an optician or check product specifications before purchasing to ensure they'll work with your plastic frames.
