My daughter has recently had an eye test which showed that she was slightly short sighted. The test occurred straight after a swimming lesson. I wanted to know whether the swimming lesson would have had an adverse affect on the eye test.

The swimming lesson should not have affected the outcome of the test. Most of the tests carried out to determine prescription are objective and we use subjective tests purely to refine the prescription. Short sight simply means your daughters eye is long and we use glasses to compensate for this. I would have no concern that the test result is not accurate.
