How to Size Tomato Glasses


There are a few different ways to determine the what size of Tomato Glasses to purchase.  This is our guide to sizing and fitting Tomato Glasses properly.


Here’s a guide to our Tomato Glasses.  Note that Tomato Glasses tend to fit SMALLER than other frames.  If this is your first time trying Tomato Glasses, you may want to order different sizes to try on your child.  We have a 30 day return policy on purchases made through our Canadian website (www.tomatoglasses.ca). See our “Return Policy” for more details.

Method 1.  Size by age.

Our first recommendation is to determine the Tomato Glasses sizing by age.  The chart below shows recommended sizes by age for each model of glasses.  First, find the model you are interested in on the left size of the chart.  After you find the frame model, you will be able to find the recommended size by age.  If your child is between two recommended sizes, then try the larger size because Tomato Glasses tends to fit smaller than other frames.  However, if your child is petite for their age, then try the smaller size.

 

Method 2.  Size by pupillary distance (PD).

The pupillary distance (PD) is the distance between the two pupils measured in millimetres.  Keep in mind that pupillary distance is only an estimate of the size of Tomato Glasses because everyone’s eyes are set different distances apart relative to the head size.  For example,  some kids have narrow set eyes (hence a narrower PD) but they may have a large head size.  Another example is if you child has strabismus (eye turn), then the PD may be too narrow or too wide.  If this is the case, then the pupillary distance will not be an accurate way to determine the size for Tomato Glasses.  Instead, refer to method 1 (size by age).

How to get your child’s pupillary distance?  An optician or optometrist can measure your child’s pupillary distance  when they provide a glasses prescription at your child’s eye examination.  After you have the pupillary distance, then you can determine the size of Tomato Glasses here:

PD is less than 42mm = Try Tomato Glasses sizes 35 to 37

PD is 42 to 48 mm = Try Tomato Glasses sizes 37 to 40

PD is 49 to 52 mm = Try Tomato Glasses sizes 40 to 42

PD is 53 to 55 mm = Try Tomato Glasses sizes 43 to 45

PD is 56 to 58 mm = Try Tomato Glasses sizes 45 to 47

PD is 59 to 62 mm = Try Tomato Glasses sizes 47 to 52

 

Method 3.  Exact measurements.

These are the exact measurements of each Tomato Glasses frame.  You can use a ruler to determine which width to try for your child.  A proper fitting pair of glasses will fit the width of the head right above the two ears.  Additionally, the eyes should be centred in the middle of the lens of the glasses.  If this is your first time trying Tomato Glasses, you may want to order different sizes to try on your child.  We have a 30 day return policy on purchases made through our Canadian website (www.tomatoglasses.ca).

How to read this chart: All measurements are in millimeters. For example, Tomato Baby A 35×13-26-35: The first number 35×13 means that the lens width is 35mm for one eye and the nose bridge is 13mm across. For every frame, the temples tend to stick out about 2mm on each side of the frame. The total width across the frame is two lenses plus the nose bridge plus two temples = 35+35+13+ 2+2= 87mm across. The height of the lens is 26mm. The diagonal length is 35mm.
