General & Contact Lens Examinations

At Preston Vision, we strive to provide the clearest possible vision using the latest technology. Dr. John performs a thorough examination to determine your prescription, and check the external and internal health of your eyes. A dilated examination helps the doctor to get a better view of the inside of your eyes, which can help to diagnose conditions such as diabetic retinopathy, retinal tears, and more.  

​

We offer a wide range of options of contact lenses to ensure you see and feel your best.

 

Our services include:

Spherical contact lens fitting

Toric (astigmatism) contact lens fitting 

​Monovision & Multifocal contact lens fitting

Training for first-time wearers (how to insert & remove a contact lens)
