Welcome to

, your one-stop destination for thorough, comprehensive, and personalized eye health solutions. Our

is committed to providing an array of tests and assessments designed to keep your vision at its best. One of these crucial tools in our toolkit is the Dynamic Visual Acuity Test (DVAT), an advanced technique for examining the quality of your vision, especially while in motion. This test is particularly important for athletes and individuals whose professions or lifestyles require exceptional dynamic vision.

The DVAT is an essential part of our

comprehensive eye examinations

Initial Consultation: We begin with a thorough understanding of your vision history and any symptoms you may have noticed. This initial consultation helps our experts to cater to your unique needs and to choose the appropriate testing mechanisms.
Pre-Test Procedures: You will be comfortably seated in a distraction-free environment. Instructions will be provided to ensure you understand the procedure fully.
The Test: You will be asked to focus on a visual target, usually letters or images, presented on a video monitor. This target starts moving at varying speeds and directions, and you will be asked to identify or track the object visually.
Evaluation: As you engage with the moving targets, your responses are recorded and analysed to determine how well your eyes perceive details while in motion. The test usually takes a few minutes and is completely painless.
Discussion of Results: Once the test is complete, our eye care professional will discuss the results with you. If any abnormalities are detected, further evaluations or treatment plans will be recommended.
Follow-up: We believe in continuous care. We will schedule follow-up appointments to monitor your dynamic visual acuity and adjust any treatment plans as needed.

What Is Visual Acuity?

What Is Best Corrected Visual Acuity?

In the vast domain of ophthalmology, the term “Best Corrected Visual Acuity” (BCVA) is commonly used. BCVA refers to the sharpest or most clear vision that a person can achieve, usually with the help of corrective lenses such as glasses or

contact lenses

How Is Dynamic Visual Acuity Test Performed?

The patient is seated at a prescribed distance from a computer screen, instead of a standard eye chart.
The patient wears an inertial measurement unit (IMU) that can track head movements in three dimensions.
Images, which could be letters, words, or optotypes (like a tumbling E or Landolt C) are displayed on the computer screen.
The patient is asked to identify these images or their directions (up, down, left, or right) while keeping the head still. This establishes the baseline visual acuity.
Next, the patient is asked to identify the images or their directions during head movements. This measures the dynamic visual acuity.
These head movements can be performed actively (by the patient) or passively (by the clinician).

Can Putting on Contact Lenses Affect Dynamic Visual Acuity Test Results?

When it comes to dynamic visual acuity tests, putting on contact lenses for first-time users may affect the results. The lenses may cause slight blurriness or discomfort at first, impacting the ability to accurately track moving objects. It’s important for new users to allow time for adjustment before undergoing visual acuity testing.

Is Dynamic Visual Acuity Test a Part of the Lasik Consultation Process?

Yes, dynamic visual acuity test is a crucial part of the Lasik consultation process. This test assesses how well your eyes can focus on moving objects, which is important for activities like driving. Understanding your lasik consultation expectations will help prepare you for the comprehensive evaluation.
