Protect your eyes from harmful light with eyeshields. Similar to sunglasses, eyeshields are designed to exclude harmful ultra violet (UV) and blue light which can damage the retina, while the different filter tints can help increase contrast and definition. They're light and easy to wear, in and outdoors and some can even be worn over your existing prescription glasses - just choose the right colour tint for your eye condition and needs. Use the menu below to find out what condition each tint is suitable for. The percentage listed for each filter is the amount of light that is transmitted through and the rest is blocked.
