Blindness is a significant health issue that affects millions of people worldwide. According to the World Health Organization, an estimated 253 million people live with visual impairments, with 36 million of them being completely blind. While some cases of blindness are unavoidable due to genetic factors or conditions like age-related macular degeneration, cataracts, and glaucoma, many cases of blindness can be prevented through early detection and intervention.
October is Blindness Awareness Month, a time dedicated to increasing awareness about blindness and vision impairments. This month serves as a reminder to educate ourselves about the challenges faced by individuals who are visually impaired and the importance of access to resources and support.
Low vision is a visual impairment that cannot be fully corrected with regular glasses, contact lenses, or surgery. People with low vision often struggle with daily tasks such as reading, writing, and navigating their surroundings. However, with the help of low vision devices such as low vision glasses, they can improve their visual acuity and quality of life.
