4.Three Key Features of RETISSA ON HAND

■ Three Key Features 

5. RETISSA ON HAND Compliant with the Reading Barrier-Free Act

■ Promotion of Visual Support Devices and the Reading Barrier-Free Act

This handheld visual support device allows for easy use of retinal projection, unaffected by visual acuity, to alleviate difficulty in seeing both near and distant objects, thereby aiming to improve the quality of daily life. Additionally, this product complies with the "Reading Barrier-Free Act," promoting its use in public institutions such as libraries and schools.

The "Reading Barrier-Free Act," enacted on June 28, 2019, in Japan, aims to improve the reading environment so that all individuals, including those with visual impairments, can benefit from the culture of written and printed text. This law applies to everyone, regardless of whether they have a disability.

6. RETISSA ON HAND: An Innovative Solution for Diabetic Retinopathy with Retinal Projection Technology

■ The Increase in Vision Impairments Due to Diabetes and Its Impact 

Diabetes is on the rise worldwide, and this chronic disease is known to cause vision impairments in the form of diabetic retinopathy. Diabetic retinopathy affects approximately 35% of diabetes patients, and if not properly treated, it significantly increases the risk of blindness. Such vision impairments have severe impacts on the daily lives of patients, leading to a decline in their quality of independent living.

■ The Current State of Global Diabetes Incidence Rates and Vision Impairments 

According to the World Health Organization (WHO), approximately 8.5% of adults worldwide have diabetes, and this number is expected to increase further by 2030. In developing countries, in particular, inadequate prevention and management of diabetes are leading to an increase in the number of people with vision impairments. This situation represents a significant public health challenge, highlighting the need for effective treatment and support systems.

■ Reasons Why Retinal Projection Technology Is a Solution 

Retinal projection technology offers an innovative solution specifically designed for vision impairments caused by diabetes. By projecting high-resolution images directly onto the retina, this technology provides clear visual information that conventional visual support devices cannot achieve. The retinal projection magnifier enables users to obtain the necessary information even as their vision deteriorates, directly contributing to the independence and quality of daily life for diabetic patients. This technology brings new hope to diabetic patients with vision impairments, providing them with the means to lead more fulfilling lives.
