Turn your Oakley Port Bow OX8164 eyeglass frame into a pair of sunglasses, or simply give it new lenses. These Oakley Port Bow OX8164 Replacement Lenses are aftermarket lenses cut in our workshop to the outline of this model, and they are sold without prescription.

Oakley Port Bow OX8164 Replacement Lenses: fit and measurements

Angular lenses have corners, and that is where a poor cut shows first: a gap at the rim or a lens that will not sit flat. This model comes in sizes 51, 53, 55 and 57: choose yours in the size selector. Before ordering, read the code printed inside the left temple: it must say OX8164, followed by the size. A lens from another model will not seat properly even if it looks similar.

• Model code: OX8164
• Sizes: 51, 53, 55 and 57
• Frame front: O Matter
• Lens curve: Base 6
• Colours: 20

Lens material, colours and coatings

Tinted lenses are polycarbonate with a Base 6 curve and UV400 protection; clear lenses are CR39 or polycarbonate, depending on the coating. There are 20 colours on this page. Solid tints: blue, green, pink, red, yellow, brown and grey. Gradients: grey gradient and brown gradient. Mirrors: gold mirror, violet mirror, ice blue mirror, black mirror, blue mirror, green mirror and red mirror. Photochromic, which darken in sunlight: photochromic blue, photochromic green and photochromic grey. Clear lenses are also available, with a blue-light filter option. Green stays close to natural colours, grey is the most neutral and brown adds warmth and contrast. Most tints can also be ordered polarized to cut glare: the options for each colour appear under the colour selector. Blue, pink and red come non-polarized only. When you pick a colour, the photo above shows it on this frame.

How to fit them

The front of the Port Bow OX8164 is O Matter. Push the old lens out from the back, pressing near the edge rather than the centre. Then seat the new one in the groove starting at one end and press round until it sits evenly all the way, without twisting the frame. If you are not confident, an optician can do it for you.

Why change the lenses and keep the frame

Changing the lenses lets you keep a frame that already fits you, and it is also a way to try another tint without replacing the glasses. If you own another pair, there are more models in our Oakley replacement lenses section.
