Background: Low vision affects millions of individuals worldwide, significantly impacting their daily activities and quality of life. While traditional aids such as magnifying glasses have long been utilized, recent technological advancements offer more sophisticated solutions to enhance functionality and independence for individuals with visual impairments.

Objective: This narrative review aims to critically examine recent advancements in low vision devices, specifically focusing on wearable technologies, electronic magnifiers, and assistive software. The review assesses their impact on users’ visual functionality, independence, and overall quality of life.

Methods: A thorough literature search was performed across electronic databases including PubMed, Scopus, Web of Science, and Google Scholar. The search was restricted to articles published between 2018 and 2024, using keywords such as "low vision aids," "wearable technology," "electronic magnifiers," "assistive software," and "augmented reality for low vision." The review followed PRISMA guidelines, which involved four key stages: identification, screening, eligibility, and inclusion. Out of the initial pool, 150 studies were selected for inclusion based on their relevance to recent technological advancements in low vision aids.

Results: Recent advancements in low vision devices have shown significant improvements. Wearable technologies, such as smart glasses and head-mounted displays, have enhanced visual acuity, navigation, and daily functioning. For instance, the eSight 4 smart glasses demonstrated a 45% improvement in visual acuity and a 50% increase in reading speed, while the OrCam MyEye 2.0 facilitated a 60% improvement in performing daily tasks. Electronic magnifiers, including portable devices like the Pebble HD and desktop magnifiers like the Merlin Ultra, have advanced in terms of image quality and user interface, with the Pebble HD showing a 35% increase in reading speed and a 40% improvement in overall satisfaction. Assistive software has also evolved, with screen readers such as JAWS 2024 and NVDA exhibiting a 30% improvement in web page navigation accuracy, and magnification software like ZoomText Fusion enhancing interaction with digital content by 40%.

Conclusion: The advancements in low vision devices have substantially improved the quality of life for individuals with visual impairments. Wearable technologies, electronic magnifiers, and assistive software have provided enhanced functionality and greater independence. Future research should continue to focus on further innovation, affordability, and the long-term impacts of these technologies on users' well-being.
