The issue of uncorrected Presbyopia is an emerging health and livelihoods problem in Bangladesh. Presbyopia is easily corrected with an appropriate pair of reading glasses. Non-governmental organizations and government agencies have been working in many emerging markets, including Bangladesh, to increase eyeglass coverage among low-income adults by introducing basic vision screening and the dispensing of reading glasses at the community level. While vision screening is typically considered a health intervention, the primary motivation of these organizations and government agencies is to correct blurry vision with the intention of improving adults' income earning potential.
VisionSpring and BRAC (previously know as Bangladesh Rural Advancement Committee. Now it is know as BRAC-no full form used) are two such NGOs who are partnering to implement a "Reading Glasses for Improved Livelihoods" program. VisionSpring is a social enterprise with a mission to increase access to affordable eye care and glasses in low-income settings. BRAC is an international development organization dedicated to alleviating poverty by empowering the poor.
VisionSpring and BRAC have initiated a Randomized Control Trial to assess the economic and social impact that reading glasses may have on individuals that earn less than $4 a day. The study hypothesizes that post-intervention, the adoption of reading glasses will increase productivity related to paid work and non-paid household activity, and will enhance the vision-related quality of life of adults with Presbyopia.
This experimental trial is designed to test the aforementioned hypotheses. In March 2017 a census survey was conducted in 59 villages of adults aged ≥35 and ≤65 years old in order to identify individuals with uncorrected presbyopia who would be eligible for enrollment in the study intervention. Following household visual acuity screenings, study participants were selected for enrollment. Randomization was conducted at the household level. Based on the inclusion criteria, a total of 1086 random households were surveyed at the baseline. Following completion of the baseline survey, in August 2017 the treatment group was given reading glasses free-of-cost. The endline survey will be conducted in May 2018, eight months from the baseline. Although some income-related outcomes may take more time to manifest, it is anticipated that the wearing of glasses precipitates changes in a relatively short time frame. The control group will receive reading glasses at the conclusion of the endline survey.

Experimental: Reading glass provided
Randomization took place after conducting the census survey. Participants were selected based on the inclusion criteria.
555 random households were surveyed at the baseline. These households have been given reading glasses free of cost.
Other: Reading glass
Participants from the experimental group have received reading glasses free of cost. Investigators hypothesize that a simple pair of eyeglasses could improve the lives of these people by enabling continued participation in the workforce, restoring productivity levels in both paid and unpaid work, and enhancing the ability to perform everyday tasks. Investigators also hypothesize that reading glasses will improve quality of life.
No Intervention: Non-reading glass
A total of 1086 households were surveyed at the baseline survey. Among them, 555 households have been provided reading glasses. The 531 remaining households were not given reading glasses during the baseline survey. The endline survey will be conducted in May 2018. Upon completing the endline survey, the non-reading glasses group will be provided reading glasses.
- Income (Bangladeshi Taka) [ Time Frame: 7 to 8 months. ]Each participant's income data will be captured before and after the intervention by structured questionnaire (e.g: how much taka you earned in last 30 days?). The data will then be calculated into per hour income before and after the intervention (8 months period) and will be compared between intervention and control group participants to see the difference.
- Secondary outcome 1: Difficulties in performing daily wise task: [ Time Frame: 7 to 8 months. ]• Likert scale (scale of 5) will be used to capture data on participants' Difficulties in performing daily wise tasks. Each question related to visual function is rated on a five-pointed scale consisting of (1) None; (2) Mild difficulty; (3) Moderate difficulty; (4) Severe difficulty; (5) Extreme difficulty.
- Quality of vision: Likert scale [ Time Frame: 7 to 8 months. ]• Self-reported quality of vision as per responses of the respondents will be measured. Measurement will be based on a five point Likert scale as (1) Very Good; (2) Good; (3) Moderate; (4) Bad; (5) Very Bad.
- Discomfort in functioning social activities [ Time Frame: 7 to 8 months. ]• Social functioning such as feel ashamed or discomfort due to eye problem in the society will be measured. Measurement will be based on a five point Likert scale consisting of (1) Never; (2) rarely; (3) Sometimes; (4) Often; (5) Very often.
