Many patients arrive for their first comprehensive eye exam at Harnos Optometry unsure of what to expect. They've had school vision screenings, maybe a quick glasses prescription update at another practice — but a truly thorough eye exam is more involved than either of those experiences, and the difference matters. Here's exactly what happens during your exam at our New Paltz office, and why each step is there.
Medical History and Current Concerns
Your exam begins with a thorough review of your ocular and medical history — current medications, family history of eye disease, any symptoms you've been experiencing. This isn't a formality. Many eye conditions have systemic links, and knowing that your father had glaucoma or that you've been on long-term hydroxychloroquine changes what we look for and how often we monitor.
Visual Acuity and Refraction
We measure your current visual acuity at distance and near, then perform a careful refraction — the process of determining your exact glasses or contact lens prescription. This involves both objective measurements (autorefraction) and subjective refinement (the "which is better, 1 or 2?" sequence that patients remember from every exam). Together these produce a prescription optimized for your visual demands — whether that's reading fine print, driving at night, or spending 8 hours at a computer.
Binocular Vision and Eye Movement
We evaluate how your eyes work as a team — checking alignment, convergence, and the ability to maintain single, comfortable binocular vision. Problems here cause headaches, double vision, and reading difficulties that many patients attribute to their prescription rather than their eye teaming.
Intraocular Pressure and Glaucoma Screening
Glaucoma is one of the leading causes of irreversible vision loss, and it produces no symptoms in its early stages. We measure your intraocular pressure at every exam and evaluate your optic nerve appearance. Patients with elevated pressure, suspicious optic nerves, or family history of glaucoma receive additional testing including visual field assessment and OCT imaging of the nerve fiber layer.
Anterior Segment Examination
Using a biomicroscope (slit lamp), we examine the external and front structures of your eye — lids, lashes, conjunctiva, cornea, iris, and lens. This is where we identify conditions like dry eye disease, cataracts, corneal irregularities, and uveitis, among others.
Posterior Segment and Retinal Examination
The back of the eye — retina, macula, optic nerve, and blood vessels — is examined through a dilated pupil or, for many patients, using our digital retinal imaging system as a non-dilated alternative. This is where we identify signs of diabetic retinopathy, macular degeneration, retinal tears, and other serious conditions. Retinal images are stored in your record for year-over-year comparison.
Your complete exam takes approximately 30–45 minutes and ends with a thorough discussion of everything we found and any recommendations for treatment or monitoring. We'll never rush you out the door — your questions are part of the visit. Book your comprehensive exam in New Paltz online today.
