A PIONEER AND ECO-FRIENDLY INNOVATION: Grand is a blending work of imagination and creativity. From the moment you hold it, you will sense the attention to detail that went into its design. Manufactured from Non-Toxic Environmental Materials, this unique design is lightweight and portable. The carefully selected material on the inside of the device and magnetic clasp, protects your smartphone and display from scratches. 42 MM PMMA LENSES MADE with JAPANESE TECHNOLOGY: Keeping in mind the optimum performance of our VR Box along with the protection of your vision, we have carefully chosen the PMMA lenses with 8 layer nano coating. The 5 times polishing of the lenses helps in blocking the electromagnetic radiations and allows high light-transmission through the lenses which makes the image clearer and in-turn reduces glare. By using unilateral myopic adjustments; you can adjust interpupillary (Range 55 - 75 mm) and smartphone distance (Upto 10 mm), which in turn helps to clear the focus.

Added Advantage with Smartphones having Gyroscope and Accelerometer features, as they help in producing a better 3D Experience with Head Tracking and Control of Orientation Based Commands.
