Size Lens Kit
The Chadwick Optical Size Lens Kit is your tool to help you correct image size differences between a patient's eyes caused by aniseikonia that isn't apparent in the refraction. The kit provides a range of afocal lenses with varying magnifications that allow you to subjectively assess and address the unequal image sizes.
The KIT
What is the Size Lens Kit?
Unlike standard lenses that correct focus, the lenses in the Size Lens Kit offer pure magnification. By viewing through these afocal lenses over their current prescription, your patient can directly experience how different percentages of magnification affect the perceived size of images between their eyes.
This subjective feedback allows you to pinpoint the magnification needed in one eye to create a more balanced and comfortable binocular visual experience. By testing in real-world scenarios, you move beyond mere acuity and address true functional vision.
The Fit
Who is the SIZE LENS KIT for?
The Size Lens Kit is specifically for your patients who report visual discomfort despite having clear vision with their regular prescription. This discomfort often arises from aniseikonia caused by a past surgery or some other anatomical variation that won't show up in the refraction.
It helps you identify the necessary magnification to balance the image sizes, improving binocular comfort and functional vision.

How to ORder
The magnification parameters you gather from the size lens kit can be added to any prescription. Whatever your patient finds most beneficial, we can work with you to get it done.
To place an order, include the magnification information when filling out our order form. Simply add the necessary magnification to the prescription for the eye with the smaller image, such as:
-
- OD +100 +5% (magnification)
- OS +100
Keep in mind, the higher the magnification, the thicker the lens will be; so, patient tolerance is a consideration. If you're concerned that your patient will dislike the lens thickness, we can work with you to find a more aesthetically pleasing way to achieve the desired magnification.
Once you've identified the magnification, you can order it for your patient in their current prescription. We have a digital version of the Chadwick Optical order form available. If you have any questions about your order, please call or email Chadwick customer service.
