Comprehensive Eye Exam
The eye doctor will use variety of test and procedure to examine and evaluate the health of the eyes. These test include visual acuity, ocular motility test, cover test, color vision test, ocular pressure, stereopsis (depth perception test), refraction and slit lamp exam with high power lens.
Presbyopia occurs due to aging, causing the lens to lose elasticity, creating a blur for near vision. At this point, the lens is no longer able to focus light directly on the retina. Instead, the light focuses behind the retina, creating the blurry vision you experience when looking at something up close. You will recognize this when you are trying to read a book, use a computer, or do anything at close distance.
Myopia, also known as “Nearsightedness”, is when you are able to see objects at a close distance, but have trouble recognizing them at a far distance. Examples; traffic signs and billboards. Commonly, nearsightedness is hereditary. The eyeball will be “too long”, measuring front to back, and causing light to focus in front of the retina, as oppose to direct on. You will find yourself squinting in order to focus and dealing with headaches from the constant straining of your eyes.
Astigmatism is a common cause of blurred vision due to an irregular shape of the cornea, which prevents light from focusing on a single point on the retina. Multiple focal points causes blurry vision at any distance, resulting in squinting, headaches, and eye strain.
