Lenses decide how you see.
Frames only decide how you look.
At Parekh Opticals, we treat lens dispensing as a custom prescription. The alignment, thickness index, and specialized coatings are selected to match your unique screen habits and vision requirements.
Lens Type Matrix

Zeiss vs Essilor vs Crizal: Our Optometrist's Review
Zeiss — Optical Precision & Customisation
Originating in Germany, Zeiss is the world leader in microscopic and astronomical optics. In spectacles, their SmartLife digital lenses are designed with high precision for visual tracking, minimizing distortion as your eyes shift from distance views to mobile phones.
Essilor — Pioneers in Progressive Design
Essilor invented the modern progressive lens (Varilux). If you have been struggling to adapt to progressives or complain of "swim" effects (peripheral blur when turning your head), Essilor’s Varilux Series offers the widest, most stable visual fields in the industry.
Crizal — The Benchmark in Protective Coatings
Crizal is Essilor's dedicated lens coating line. While Zeiss excels in raw optical glass formulas, Crizal is the gold standard for lens longevity. Their coatings protect against the "5 enemies of vision": scratches, reflections, smudges, dust, and water.
