The CYL figure helps to correct an Astigmatism - which means the eye has problems focusing at particular angles. The eye will be slightly rugby ball shaped rather than football (soccer for our American customers!) shaped.

Featuring HYDROFREAK™ lenses for optimal protection and ZEROFORM™ frame material for comfort. The price is an incredibly important consideration for buying any product, so we’re going to delve into the price of O’Neill Sunglasses ONeill CHAGOS Polarized 103P and see how it compares to the other alternatives from O’Neill or competitor products in the Men’s Accessories category. The simplest way for you to get the right frame size is to read the measurements from a comfortable pair of sunglasses (or glasses) that you already own. Often, your sunglasses will have wider lenses than regular glasses (to better protect against the suns rays) so it's probably better to read the measurements from your sunglasses. You can usually find the dimensions (perhaps with the help of a magnifying glass) on the inside of the arms/sides of your sunglasses and occasionally on the inside of the bridge (the part of your sunglasses that sits on your nose). This figure designates the strength of lens needed to correct your focus: A positive (+) SPH for long sightedness (problems focusing on close objects) and a negative (-) SPH to correct short sightedness (problems focusing on far objects). If you are neither short nor long sighted, on your prescription, you will see the word PLANO or PL, or the figure 0 (sometimes 0.00), or the sign for infinity:∞ However, this does not necessarily mean you have perfect eyesight as you may have an astigmatism (see below).

If there are 2 PD measurements shown on your prescription, such as 63/60, this will mean that the 63mm figure is for distance use and 60mm will be your reading or computer PD.
