Contact lenses sit directly on the eye, while glasses sit approximately 13mm from the eye. This distance creates a magnification (farsighted)/minification (nearsighted) effect. If you have astigmatism or a high prescription this effect can increased. It could also mean that your glasses were made wrong or the measurements were wrong. A quality pair of glasses should not create this effect for you. It is one of the main complaints of online glasses actually.

The first step would be to take the glasses in to get adjusted. If the frame has too much wrap or tilt it can increase this effect. Sometimes a simple adjustment can fix the problem

The next step is to book another appointment with your Optometrist to check on the prescription.

Sometimes it is a good idea to take the glasses to a third party Optometry office. Most places will check out your glasses for you for a minimal charge.
