For most people the standard fit should be fine. If you know the size of your old frame enter it in the drop down boxes on the orderpage and choose a frame with similar sizes – unless of course you want to try a new frame style and size, then your old frame size will give you a good reference to work from. If you don’t know the size of the frame you require here are some guidelines Don’t choose a frame that is too large, visual distortion and glare can occur. If your frame is too small, you limit your peripheral vision.

Generally, the frames shouldn't be wider than the widest part of your face, with the exception of frames for oval faces, which can be a little wider. When you put on a pair of glasses, your eyes should look out of the centre of each lens. The frames should not be so tight that they pinch your nose or leave red marks. Conversely, they should not be so loose that they slide down your nose. If they have nose pads, try adjusting them very gently.

Tip: The top of the frames should not be above the eyebrow line and the bottom shouldn't touch your cheeks, so they don't irritate your skin. Finally, they should be comfortable around your ears. If your frames become uncomfortable over time, pop into a spectacle shop and ask them to help you adjust them. Usually, adjustments are free. You can try to adjust frames yourself but be very careful because they break easily if you force them.

Determine size of your face

The letters next to the frame below are measurements in mm (millimetres). The first letter A is the width of the lense. In this picture it is 52. The second (C) is the distance between the lenses (DBL) in other words the bridge width. In this picture it is 18. The third letter E is the full temple length (TL) - length of the arm . In this picture it is 135 (Including the part that goes behind your ear).- 52/18/135

The total width of the frame is the distance across from the far left to the far right of the frame when looking straight at it. In this picture it is 140 and the lens height is 35. These 2 measurement are not usually found on the frame.

These dimension details are shown below

Tip 1 : Lens height is important if bifocals or progressive lenses are ordered so choose a frame or lens shape suited to them, a small lens height is normal for children. It is possible for you to have a frame that has a 52mm lens width and another frame with a 48mm lens and they both fit perfectly. These numbers are not precise, they are meant as a guide only. In fact many frame companies now only manufacture in one or two sizes. All of our metal frames are manufactured with the highest quality materials and finishes and our frames have adjustable nose pads and bend-able temples, so they are simple for you or an Optician to adjust!

The contemporary designs, durable lightweight construction and high finishes of our frames produce stylish and comfortable fits and the frames come in many sizes and shapes. Should you require a special size or shape of lens, then order one of our rimless frames and choose a lens shape and size from our list of 50.

Tip 2 : To see how wide your face is, just look in the mirror with an ordinary ruler resting on the top of your nose and measure the total width of your face. You will also need to find your pupilary distance (P.D.) Do this by measuring the distance, in millimetres, between the centres of your two pupils (black spots in the centre of your eye). The number should be somewhere between 40-90 millimetres.Most people have a distance of 63. Enter the P.D on the prescription page.
