The BPL Studylite is designed and developed based on the study and survey of literature on the essential components of lighting related issues for the task of reading. The survey was carried out by the faculty and post graduate students of Elite School of Optometry.

Inputs of the findings were given to the BPL team on standards for illuminance, reading area, uniformity index, IR & UV tolerance, colour rendering index, glare, etc.

This study lamp is 'green' because it uses the LED, the so-far most energy efficient light producing device. The product has a rechargeable battery. The battery can be charged from AC mains as also from BPL u.power SP 1000 Solar Panel. The lamp enables uninterrupted reading since the battery provides a back up of 6 hours.

Sankara Nethralaya has tested this studylite with 18 subjects in the age bracket of 13 to 25 years who were screened for normal vision parameters.

For all the 18 subjects, variance in the visual functions such as Visual acuity and Contrast Sensitivity (using SVIS Chart), Color vision (using achromatic setting), Stereopsis (using Titmus Stereo Test), Tear function (using Schirmer’s strips), and Reading speed (using SNREAD) are checked and effects found in the analysed parameters are well within the clinically accepted values.

The studylite has been checked with and without ambient light.
