Choosing eyeglass lenses is more than picking a stylish frame. Patients rely on their eye care providers to recommend lenses that match lifestyle, address ocular conditions, and support long-term visual health. In this episode of the Eye – Q Podcast, host Dr. Rudrani Banik sat down with Dr. Jennifer Tsai, optometrist, business owner, and national media authority, to share her expertise on navigating lens options, managing dry eye, and guiding patients through the complexity of modern eyewear choices.

The Three O’s and Why Co-Management Matters
One of the first challenges patients face is understanding the “three O’s” of eye care: optometrists, ophthalmologists, and opticians. Dr. Tsai explained that optometrists serve as the primary eye care providers for most patients, offering comprehensive exams, prescribing glasses and contact lenses, and managing ocular disease. Ophthalmologists step in for surgical or advanced medical care, while opticians provide expertise in fitting and dispensing glasses.
Dr. Banik emphasized that patients should view both optometrists and ophthalmologists as “eye doctors.” Comprehensive exams go beyond vision checks and glasses—they include dilation, ocular health evaluations, and screenings for systemic conditions like hypertension or diabetes. Co-management between specialties ensures patients receive seamless, full-spectrum care.
From Patient Story to Practice Model
Dr. Tsai’s path into optometry was shaped by her own experiences with serious eye issues, including a corneal ulcer and retinal tears. Those encounters revealed how essential vision is in daily life and how much patients depend on compassionate care. Inspired by these experiences, she pursued optometry to provide preventive care in a setting that emphasized both clinical excellence and meaningful patient relationships.
In 2020, during the height of the pandemic, Dr. Tsai opened her own practice, Line of Sight, in New York City. She envisioned a concierge model that merged medical eye care with the hospitality of a luxury service experience. Her focus has been on proactive therapies, patient education, and an environment where every patient feels cared for personally.
Dry Eye: Root-Cause Evaluation and Therapy
Many patients struggling with dry eye are given only lubricating drops, which often provide incomplete relief. Dr. Tsai described her process of looking deeper into the root causes through lid evaluation and imaging of the meibomian glands. By identifying whether the glands are clogged, atrophied, or inflamed, she can create personalized treatment plans.
Her practice incorporates therapies such as intense pulsed light (IPL) for blepharitis-related dry eye, radiofrequency for meibomian gland dysfunction, and advanced regenerative options including amniotic membranes and stem-cell–based approaches. Patients may also benefit from prescription drops designed to improve tear or oil production. Often, successful outcomes require a combination of these strategies.
Contact Lens Strategy for Dry Eye and Scleral Lenses
For patients with dry eye, wearing contact lenses can feel like a challenge. Dr. Tsai emphasized that the goal is not to limit patients’ lifestyles but to find a balance between treatment and safe lens wear. In some cases, she recommends limiting use to special occasions until dryness is under control. Daily disposable lenses are often better tolerated by patients with heavy screen use or ocular surface sensitivity.
When traditional lenses are not viable, scleral lenses offer an effective alternative. These larger, rigid lenses vault over the cornea and are filled with saline, creating a smooth optical surface while protecting and hydrating the cornea. They can provide both comfort and excellent vision for patients with keratoconus, corneal scarring, or severe ocular surface disease.
UV Safety: Polarized vs UV Protection
One of the most common misconceptions among patients is that polarized lenses automatically provide UV protection. In reality, polarization is designed to reduce glare from reflective surfaces such as water, snow, or roads, making them excellent for outdoor sports and driving. However, they do not inherently block UVA and UVB light.
True UV protection requires lenses that are certified UV400, blocking both UVA and UVB wavelengths. Importantly, the darkness of a lens tint does not indicate UV safety. In fact, darker non-UV lenses may increase risk by dilating pupils, allowing more harmful light to reach the retina. Ensuring patients understand this distinction is critical when counseling them on sunglass purchases.
Tints, Filters, and Blue Light Blocking Lenses
Lens tints play a powerful role in tailoring eyewear to individual needs. Gray lenses maintain color balance and are useful for general outdoor wear. Brown or amber tints enhance contrast and depth perception, making them excellent for driving, golfing, or fishing. Yellow tints can assist in low-light conditions, while rose or FL-41 tints are valuable for patients with migraine or light sensitivity.
Blue light blocking lenses continue to generate interest. Light, nearly clear filters may only block 10–20% of blue wavelengths, while deeper amber or red lenses can block nearly all, though with noticeable color distortion. Contact lenses with integrated blue light filters, such as certain daily disposables, add another layer of protection for screen-heavy patients.
Counseling Patients on Choosing Eyeglass Lenses
Dr. Tsai underscored that lens selection should be guided by lifestyle. Patients who spend hours on screens, drive at night, or engage in outdoor activities each require different solutions. Multiple pairs of glasses may be necessary: computer lenses with anti-reflective coating, UV-blocking sunglasses, and night-driving lenses with enhanced contrast.
She also reminded practitioners that glasses are much like clothing—different pairs serve different purposes. Just as patients rotate wardrobes for the seasons, they should consider separate eyewear for different visual demands. Presenting lenses as part of a system rather than a single purchase helps patients understand the value of having more than one pair.
