At Glasses online we pride ourselves in offering a range of products to suit different budgets, lifestyles and needs. Our frames come in four sizes (based on internal frame width): small (less than 125mm), medium (126-130mm), large (131-135mm) and extra-large (more than 136mm).

Additional frame measurements can be found on the inside arms of every pair of glasses. The first number refers to the lens width, the second number refers to the bridge width and the third number refers to the side length. For an accurate fit, compare the numbers of a frame you own to the numbers on screen.

Using our Best Fit Machine, you will always be able to find the perfect fit for your glasses. Simply enter the relevant measurements and you will be presented with a list of frames that fit your measurements. If you are considering purchasing a new pair of glasses, you might want to consider your current pair first.

Can you tell me how to select the right pair of glasses for me?

In a market where there are more than 1000 styles to choose from, it can be difficult to determine which style is most appropriate for you. You may, however, find that certain glasses are more suitable for you based on the shape of your face. We can help you with this by providing a helpful Face Shape Guide.
