Your ophthalmologist will assess your eye and check the vision clarity. Your doctor might ask you to go through an eye chart test to check your vision from a distance. The doctor might also check your eye pressure. This is known as the tonometry test.
To check your pupils, the doctor might put drops in your eyes which will make the pupils bigger. This is done to check the optic nerve and to confirm if there is any damage to the retina of the eye.
The ophthalmologist might ask you to do a few more tests to check your eye's sensitivity to glare and perception of colors.
