Contact Lens Fitting
contact lens fitting
At Eye Sight Centre, Varanasi, we treat contact lens fitting as a clinical procedure, not just a retail transaction. Under the expert supervision of Dr. Richa Srivastava, we ensure that your lenses provide optimal oxygen flow, comfort, and crisp vision without compromising your long-term ocular health.
A poor fit doesn't just feel "scratchy"—it can lead to corneal hypoxia (oxygen deprivation), infections, or chronic dry eye.
Our Fitting Process
Unlike a standard eye exam, a contact lens fitting focuses on the topography of your eye and the quality of your tear film.
1. Corneal Mapping (Keratometry)
Finding the 'Base Curve'
We measure the exact curvature of your cornea. A lens that is too steep will "choke" the eye, while one too flat will slide excessively and cause irritation.
2. Tear Film Evaluation
Ensuring Comfort
Dr. Srivastava assesses your tear production. If you have dry eyes, we select specialized daily disposables or silicone hydrogel lenses that retain moisture better than standard materials.
3. Diagnostic Trial
The 20-Minute Test
You will wear a trial pair in the clinic for 20 minutes. We then use a slit-lamp microscope to observe the "centration" and "movement" of the lens as you blink.
4. Handling & Hygiene Training
Safety First
Our staff provides hands-on training for first-time wearers, covering the "pinch" removal technique and the strict "No Tap Water" cleaning protocol.

Important Safety Guidelines
- The "3-S" Rule: Never Sleep, Shower, or Swim in your contact lenses unless specifically cleared by Dr. Srivastava.
- Replacement Schedule: Respect the "Daily," "Bi-weekly," or "Monthly" limits. Over-wearing lenses is the #1 cause of contact lens-related ulcers.
- The Red Eye Rule: If your eye is red, painful, or blurry—remove the lens immediately and call our center.
