Recent social media claims suggest that sunglasses could be harmful to eye health. However, medical professionals provide a more nuanced perspective on the importance of protecting your eyes from UV radiation.
In the age of social media, misinformation can spread faster than ever. Recently, content creator Dennis Echelbarger made a controversial claim that has caught the attention of many. According to Echelbarger, sunglasses are detrimental rather than beneficial. He argues that they “block essential sunlight that is crucial for the mitochondria in our eyes,” potentially leading to severe eye conditions like macular degeneration, myopia, and glaucoma.
However, Dr. Navya C, a senior consultant in Ophthalmology at Athreya Super Specialty Hospital in Bengaluru, challenges these assertions. She emphasizes that sunglasses serve primarily to shield the eyes from harmful ultraviolet (UV) rays, which are known contributors to various eye diseases, including cataracts and macular degeneration. According to Dr. Navya, “Scientific research, including studies published in the Journal of Ophthalmology, supports the use of UV-blocking sunglasses to prevent damage to the eye’s surface and internal structures.”
The debate doesn’t stop at sunlight. The ophthalmologist also highlights concerns about prolonged exposure to artificial light, especially the blue light emitted by digital devices. She notes that this exposure can increase the risk of macular damage and suggests using glasses with blue light filters and taking regular breaks from screens to mitigate these risks.
Another point of contention is the size of the sunglasses. Dr. Navya addresses the controversial notion that smaller sunglasses might be beneficial by allowing some sunlight to reach the eyes. However, she points out that while small amounts of UV exposure can aid vitamin D synthesis, the potential risk of UV damage often outweighs these benefits. She recommends larger, wrap-around sunglasses for more effective protection against harmful UV rays.
In regions with intense sunlight, like many parts of India, Dr. Navya advises wearing broad-spectrum UV protection sunglasses that block out 99% to 100% of UVA and UVB rays. She also suggests that while it’s important to protect the eyes, moderate sun exposure to other parts of the body, with proper skin protection, is beneficial for overall health and vitamin D synthesis.
In conclusion, while it’s essential to consider how best to protect our eyes from both natural and artificial light, expert advice and scientific research advocate for the use of proper sunglasses as a defense against potential eye damage rather than a cause of it.
