Folding Foropter (FoFo) is a novel device developed by the LVPEI Center for Innovation, Hyderabad to combat the lack of access to tools for Refractive Error screening in low resource areas. FoFo is eco-friendly, affordable, and easy to use!
Uncorrected Refractive Errors are the largest cause of avoidable blindness in the developing world. Visual impairment can have immediate and long-term consequences in children and adults, such as lost educational and employment opportunities, and impaired quality of life. However, refractive errors can simply be diagnosed, measured, and corrected with the aid of spectacles and contact lenses, or by refractive surgical procedures.
people affected due to Refractive Errors.
million visually impaired
43% of visual impairment is due to uncorrected refractive errors.
in low-resource areas
Current data suggests that more than 90% of people with Uncorrected Refractive Errors worldwide reside in rural areas and low-income countries.
Today, FoFo is making an impact in 18 countries!
Inspired by the Foldscope by Dr. Manu Prakash, the Folding Foropter is a simple paper cut-out that folds around two lenses, forming two tubes that slide in and out of each other. The user then needs to look at a fixed target through the device and slides the tube to see the target clearly. The device has a simple scale that then gives the approximate refractive error.
They (Folding Foropters) were fantastic and really helped us to identify the appropriate lens strength for our patients.
The gift of sight opens an entirely new realm in which to experience life. I want to thank you and your team for all you’ve done to create the Folding Foropter.
