Eye and Vision Exam

At Valley View Vision Center, we strive to provide comprehensive, primary eye care for the whole family. Preventative and routine eye exams are important to maintaining good eye health. Often, eye and vision problems do not have obvious symptoms or signs, but are easily diagnosed by a licensed optometrist. By diagnosing eye and vision conditions early on, our optometrist is able provide treatment options and in many cases restore or prevent vision loss. The American Optometric Association recommends yearly or bi-yearly eye and vision exams, depending on whether you are at-risk or not.

Eye Exam and Consultation

During an eye exam, Dr. Wang will ask you questions about any symptoms or issues you are experiencing, medications you are currently taking, any blurry vision, your work environment, and your overall health. Family history and previous eye or vision conditions will also be discussed during this part of the examination. Wang will consider this information when determining any treatments or recommendations.

Vision Testing

Regular vision testing and evaluations ensure that you always have the clearest vision possible. Our Roanoke optometrist provides regular vision acuity test as part of a comprehensive eye exam. Wang will measure how each eye is seeing by using a wall eye chart and a reading eye chart. The results of these tests are portrayed as a fraction, with 20/20 being the standard for normal distance and reading vision. Depending on the results of your vision test, Wang may prescribe corrective glasses, contacts, or eye exercises.

Eye Function Testing

In addition to vision testing, an eye exam in our Roanoke office includes testing eye functionality. Our optometrist performs several tests to evaluate depth perception, color vision, eye muscle capabilities, peripheral vision, and responsiveness to light. Several other simple tests are completed to determine whether the eyes are focusing, moving, and working together properly. The test results enable Wang to diagnose any underlying conditions that may be impairing the eyes ability to focus or work together.

Eye Health

As part of a comprehensive eye exam, our Roanoke optometrist examines the overall health of the eye through a visual examination and tonometry. Dr. Wang evaluates eye health by visually inspecting the eye and eyelids using magnification and a bright light. To examine the internal structures of the eye, we may dilate the pupils. Increased eye pressure may be an indicator of glaucoma, so we utilize tonometry to measure eye pressure. After completing these short tests, Wang reviews the results and discusses any necessary treatment options with you

Contact Lens Exams

At Valley View Vision Center, we strive to meet all of your eye and vision care needs. Corrective lens evaluations and prescription management are provided by our optometrist in Roanoke. After a comprehensive eye and vision evaluation, Dr. Wang will discuss the variety of contact lens options with you to select the type that best fits your vision needs and lifestyle. If you suffer from dry eye, allergies, or recurring eye infections, speak with our staff to determine whether contact lenses are right for you.

Evaluation

Prior to prescribing contact lenses, Wang determines what level of vision correction you require. Refractive error (commonly known as nearsightedness, farsightedness, or astigmatism depending on the error) is evaluated by measuring how the eyes focus when a series of different lenses are placed in front of them. An optometrist may use either a phoropter or an automated instrument to take these measurements. To schedule an appointment for a vision evaluation with our Roanoke optometrist, call (540) 491-9166 today.

Corrective Lenses

After determining the level of refractive error, Dr. Wang works with you to determine whether contact lenses or glasses are best for your lifestyle. If you suffer from certain conditions, such as dry eye or allergies, glasses may be the most comfortable corrective solution. Contact lenses are available in either soft or rigid gas permeable form. Contact lenses need to be changed daily, weekly, bi-weekly, or monthly, depending on what type of lens you select. Specialized contact lenses, such as bifocal contact lenses, are also available for patients with special eye conditions. Call us at (540) 491-9166 if you are interested in learning if contact lenses are a good fit for you.

Hard to Fit Contacts

Finding contact lenses that fit and wearing contact lenses in general can be made more challenging when these conditions affect your eyes: astigmatism, dry eyes, giant papillary conjunctivitis (GPC), presbyopia. However, it does not rule out wearing contact lenses altogether. It just means patients need to discuss options with their eye care provider and obtain specialized hard to fit contacts for their specific vision problems.

 

Gas permeable lenses are a good solution for patients who suffer from GPC. A GP lens will limit protein deposits from accumulating which will reduce GPC symptoms.

 

Toric lenses are useful for correcting astigmatism. Since the lens needs to align with the bulge it is correcting, toric lenses must not rotate in order to fit on the eye. They are typically custom made to correct a specific astigmatism. For that reason, this type of lens takes longer to make and costs more than a traditional contact lens.

 

Bifocal and multifocal lenses can help remedy presbyopia. Monovision lenses are another option for presbyopia. This type of lenses can have one fitted for distance vision and the other for seeing close objects.

 

Medicated eye drops can be an effective solution for dealing with dry eyes. They will lubricate eyes enough to make contact lenses more bearable, although a punctual occlusion also must be done to plug the ducts in some extreme cases. GPC symptoms can also be lessened through medicated eye drops. They flush out protein deposits and reduce inflammation.
