Abstract
|
Before
In 2013, the World Health Organization (WHO) set eye health as a priority by creating the“Universal Eye Health: A Global Action Plan 2014-2019.” The WHO’s reasoning is intuitive; poor visual health can impair quality of life in a number of ways- by limiting physical activity, causing emotional health problems, damaging work performance. In India, 55million people suffer from presbyopia (the degeneration of sight related to age). Apart from the large-scale negative impact on quality of life, untreated visual impairments including presbyopia, are estimated to cost the Indian economy $37 billion in productivity losses annually. In this study, we aim to explore the effects of addressing presbyopia of workers in the context of the readymade garment industry in India. We will screen workers and provide eye glasses to those that have a presbyopic refractive error. We will explore adherence to eyeglasses, price sensitivity, effects on productivity and retention of such workers.
To do so, we propose a large-scale randomized controlled trial (RCT) in India which will: 1)measure adherence to eye glasses and willingness to pay of presbyopic sewers with glasses either free of cost or upon the payment of a nominal amount; 2) We will observe whether being in different treatment groups influences how regularly the worker wears glasses to work.

We will screen workers and provide eyeglasses to those with a presbyopic refractive error. We will explore adherence to eyeglasses, the effects on productivity, and the retention of such workers.
To do so, we propose a large-scale randomized controlled trial (RCT) in India which will: 1) measure adherence to eyeglasses; 2) observe the impact of glasses wear on productivity and attrition rate among these workers.

Experimental Design (Public)
|
Before
Participants will be randomized to receive glasses paying a nominal amount or for free. The latter will be randomized once more to one of three treatment arms with different monitoring mechanisms for adherence.
|
After
Participants will be randomized to decide their allotment to the treatment group (receive glasses at the start of the study and assistance mechanism for glasses adherence) or the control group (receive glasses at the end of the study).

Sample size (or number of clusters) by treatment arms
|
Before
110 workers pay for glasses: 55 pay a nominal amount, 55 get a surprise discount; 80 workers receive glasses for free, 80 workers receive glasses for free and are monitored by supervisors and 80 workers receive glasses for free and are monitored by vision champions
|
After
Treatment group: 525 adults receive glasses at the start of the study and assistance mechanism for glasses adherence; Control group: 524 adults receive glasses at the end of the study.
