It also describes the distances at which you can see clearly. A prescription should provide good vision and allow you to wear glasses comfortably. You should also ask your doctor if you have any eye allergies or health conditions. These questions will help you learn more about your eyes and your vision.

Your doctor may also ask you to perform various tests. These tests can help them to determine if you need glasses or contacts. They may also help to determine your refractive error, which is the ability of your eyes to focus on images. A refractive error can be corrected through eye surgery, glasses, or contacts. You may also have to undergo additional tests depending on your age and medical history.

You may also be asked to use a pachymeter to measure the thickness of your cornea. This is done by placing a small probe on the front surface of your eye. The thickness of your cornea is determined by the amount of light waves that are bent by the lens and the cornea. As you age, your cornea gets stiffer and less able to bend light waves.

Your doctor may also use retinoscopy to test your refractive error. This test uses light to determine how clear your vision is. Retinoscopy can also be used to test other eye disorders, such as glaucoma or macular degeneration. Your doctor may also need to use other tests, such as imaging, to determine if you have eye disorders.
