Metal

Metal sunglasses are available in a variety of shapes, including round, rectangular, square and larger sunglass designs. Depending on the individual frame, materials may include stainless steel, titanium or other metal alloys.

Compared with many plastic sunglasses, metal frames tend to have a finer rim around the lenses. Some designs also use adjustable nose pads, which can help fine-tune how the frame sits on the bridge of the nose.

Frame size is particularly important when prescription lenses are being fitted. Lens width, bridge width and temple length can help you compare a new pair with glasses or sunglasses that already fit comfortably.

The frame is only one part of choosing prescription sunglasses. The lenses also need to suit your prescription and how you expect to use them.

Depending on the selected frame and prescription, available choices may include:

• Single vision prescription sunglass lenses
• Bifocal or varifocal options where suitable
• Different sunglass tint colours
• Different tint levels
• Higher-index lens materials
• Anti-reflective treatments where available
• UV protection options

Not every lens combination will be available with every frame, so it is important to check the specific product before ordering.

For stronger prescriptions, frame size and lens shape can influence the thickness and appearance of the finished lenses. A very large sunglass frame may therefore require different consideration from a smaller metal design.

Prescription sunglasses can be made with different lens tints depending on the options available.

The tint affects the appearance of the lenses and how much visible light passes through them. Some customers prefer a neutral everyday sunglass tint, while others may choose a different colour depending on personal preference and intended use.

If the sunglasses will be used regularly for driving, holidays or general outdoor wear, check the available tint and lens specifications for the frame you are considering rather than assuming every pair offers the same choices.

Metal and plastic prescription sunglasses provide different frame styles while serving the same basic purpose: prescription vision correction with sunglass lenses.

Metal frames often have a finer profile and may include adjustable nose pads. Plastic sunglasses usually have thicker rims and are commonly available in a broader range of solid colours and more prominent shapes.

Neither material is automatically better. The most suitable option depends on your prescription, preferred fit, frame size and the sunglass lens options available.
