At Crystal Vision Center, we know that comprehensive eye exams are the foundation of all good vision and eye care. You depend on our optometrist to catch subtle changes as early as possible, and we have high diagnostic standards for each and every one of our exams. That's why we use precise tools and a variety of detailed tests for our eye exams, including dilating eye drops for dilated eye exams. The effects of dilation last for a few hours after your dilated eye exam, so it's important to be prepared before you come in. Let's learn more about the process of eye dilation, why it's important, and which eye conditions we can detect thanks to eye dilation.

How Eye Dilation Works

Before your next eye exam begins, your eye doctor may "prep" your eyes with a few drops of dilating eye drops. Dilation is an important part of several routine eye exams and tests, and it simply involves the use of special drops to improve visibility. After the drops are applied, your pupil will begin to enlarge, increasing your light sensitivity until your eyes are ready to be examined. Eye dilation itself may take up to half an hour, depending on your eyes and your optometrist's diagnostic needs.

Benefits of Dilation During Eye Exams From Your Local Optometrist

So, why do we need to enlarge your pupils and increase your light exposure? Dilation is actually the only way for your optometrist to get a glimpse of your whole retina. Before dilation, it's difficult to see all the way to the back of your eye, but dilation illuminates your optic nerve for diagnostic purposes. Your optic nerve is crucial for your vision and eye health, and it may contain telltale information about degenerative diseases before any other symptoms are apparent.

Conditions We Diagnose with Dilated Eye Exams  

We use dilated eye exams to diagnose a variety of different eye conditions and injuries. Here are some of the most common conditions that we diagnose with dilated eye exams:

  • Macular degeneration – Age-related degeneration may cause deposits, abnormal blood vessel growth beneath the retina, or deterioration of the macula, which are all more visible after dilation  
  • Diabetic retinopathy – Dilation increases light exposure throughout the retina, allowing our optometrist to check the light-sensitive tissue behind your pupil for the earliest signs of diabetes  
  • Glaucoma – This degenerative disease affects the optic nerve first, so it's important to get a good look at the whole nerve, inspecting its shape, color, and disc for abnormal changes
  • Ocular tumors – Dilation helps to expose any abnormal growth in the eye, including malignant or benign tumors in their early stages
  • Retinal tears – If you show symptoms of a retinal tear or detachment, dilation is necessary to inspect the back of your retina

Reviews From Our Satisfied Patients

  • "We use Anderson Optometry for all of our family’s vision needs. Recently, we had to have our youngest fitted for new glasses and he made the experience fun for her and informative for us. We know Dr. Anderson will always take good care of our family’s eye care and that’s why we wouldn’t go to anywhere else."

  • "Dr. Anderson and his staff are so patient and friendly. Dr. Anderson prescribed me glasses and I had the toughest time picking out frames. They didn’t rush, but instead made helpful suggestions and now I have an awesome pair of frames, not to mention the fact that I can see ten times better than before. You guys are the best!"
