Please follow the instructions below to determine which size eye patch will best accommodate your needs. Please make sure to measure carefully as the eye patches are not returnable once the package has been opened.

Using a tape measure, measure around your entire head, following the path of where the strap would rest. If you do not have a tape measure, use a piece of string or a belt to measure around your entire head, then use a ruler to determine the total length. Use this circumference measurement to determine which eyepatch would fit you best.

The diagram below shows the eye patch with dimensions.
