Eye & Vision Exams

An eye exam consists of a series of tests performed right here at Dr. Obermark Eye Health Care, assessing your vision and ability to focus on objects near and far. Having your eye checked regularly could detect potentially threatening eye diseases that could be treated if caught early.

Eye & Vision Exams

First, we start with a visual acuity test, this is where you read letters from a chart to measure the sharpness of your vision. We use a projected eye chart to test your vision at a distance and a hand-held chart to measure your near vision. When then perform a test called Retinoscopy, which helps determine an approximate prescription for your eyeglasses. The eye doctor has you focus on a letter at a distance and shines a light into your eye to see how you focus light. This gives the doctor a better understanding of where to start the refraction.

A refraction test measures the exact prescription for your eyeglasses. During the refraction, the doctor puts an instrument in front of your eyes called a phoropter. The instrument is used by showing you a series of lens choices, you then pick between one of the two choices which are the clearest. Based on your choice, the doctor changes the lens power until reaching your best fit for your prescription.

We also use an instrument called a slit lamp, which is a light that we look into your eye with and can measure the structures of your eye under high magnification. We can detect a wide range of eye diseases with this instrument such as cataracts, macular degeneration, diabetic retinopathy, and corneal ulcers.

The hand-held device called Icare, which we use to test pressure in your eyes, can get a reading normally between 10-20 if your pressure reading is higher than 20 you could be at risk for glaucoma. The pressure is built up when fluid in your eyes doesn’t drain as it’s supposed to, causing damage to the optic nerve making your vision blurry, or causing blindness.

During a routine check, the doctor may want to dilate your eyes, making your pupils larger so the doctor can see the inside structure of your eye better. Dilation is very important, especially in people with higher risks of eye diseases because it allows for the most thorough examination of the health of the inside of the eye. The effects of the drop can cause blurriness focusing up close and makes you light-sensitive, sunglasses are recommended when coming to the eye doctor, however, we usually provide disposables for you if you do not have a pair of sunglasses. The drops start to wear off after a couple of hours depending on the strength of the drop.

During your comprehensive encounter, the doctor may recommend other tests due to things he or she found while examining your eyes such as a visual field to test for blind spots or an OCT to check the thickness of the macula and optic nerve.
