(Picture credit: Freepik)Dr Himanshu Mehta, senior ophthalmologist at ASG The Vission Eye Centre, told HT Lifestyle that reading while sleeping is not advisable, as it may strain the eyes and cause temporary discomfort.Why should you avoid reading while lying in bed?The first thing the ophthalmologist clarified was that reading in this position does not cause permanent eye damage. However, it may still trigger temporary symptoms that cause discomfort.“Your eye muscles have to work harder at an unnatural angle to keep the text in focus, which can cause headaches, blurred vision, and stinging,” Dr Mehta explained the reason behind the discomfort and the resultant symptoms.Another reason he mentioned was that most people are unable to maintain the ideal reading distance of 15 inches while lying down. The book is held much closer to the eyes, forcing the eye muscles to work harder to focus and potentially causing a temporary increase in eye pressure.“If you have glaucoma or a condition that requires you to avoid fluctuations in eye pressure, you should avoid this position,” the ophthalmologist warned who should avoid this position.What are the other unsafe everyday practices for eye health?Often while reading, many people may feel nauseous while travelling in a car. (Picture credit: AI generated)Apart from lying in bed and reading, there are several other habits that you may practice daily without thinking twice, but they could silently affect your eye health. In the short term, it may not appear to cause much harm, but soon, in the long run, the consequences can become more serious.The ophthalmologist outlined these three other unsafe habits, why they are problematic, and1. Reading in moving vehiclesThe inner ear senses movement, but the eyes are glued to a static book, signalling the brain that you are still. It causes sensory mismatch and confuses the brain, and triggers nausea.Constant movement in a car forces the extraocular muscles to work harder to keep the text in focus, leading to temporary eye strain rather than lasting damage.2. Rubbing eyesAggressive or chronic rubbing can cause microscopic tears in the surface blood vessels and transfer bacteria from the hands, increasing the risk of infection.Constant pressure over time can weaken the cornea.In the long run, there are chances of this mechanical stress leading to keratoconus, a condition where the cornea progressively thins and bulges into a cone shape, severely distorting vision.3. Reading in dim lightPupils dilate in low light, making it more difficult for the eyes to focus.As a result, the muscles around your eyes have to work harder, leading to temporary eye strain.You may experience fatigue, dryness and tension, collectively known as asthenopia.Although uncomfortable, these symptoms usually subside after resting your eyes.About the expertDr Himanshu Mehta is an ophthalmologist at ASG Eye Hospital, Mumbai, with over 30+ years of experience in eye care.

As a lifestyle journalist, she crafts compelling, relatable narratives across diverse touchpoints of the human experience, including wellness, mental health, relationships, interior design, home decor, food, travel, and fashion that gently nudge readers toward living a little better. For her, stories exist in flesh and bones, carried by human vessels and shaped through everyday endeavours. It is the small stories we live and share that make us human. After all, humans and their lores are the most natural and raw repositories of stories, and uncovering them, for her, is akin to peeling an orange under a winter afternoon sun. Always up for a chat, she believes the best stories come from unfiltered yapping, where "too much information" is kind of the point. A graduate of Indraprastha College for Women, University of Delhi, and an alumna of the Indian Institute of Mass Communication (IIMC), Delhi, Adrija spends her idle hours cocooned with herbal tea and a gripping thriller, scribbling inner monologues she loosely calls poetic pieces, often with her succulents in attendance. On lazier days, she can be found binge-watching, for the nth time, one from her comfort-show holy trinity: The Office (US), Brooklyn Nine-Nine, or Modern Family. Dancing by herself to her peppy playlists, however, is an everyday ritual she swears by religiously.Read MoreEye StrainCatch every big hit, every wicket with Crick-it, a one stop destination for Live Scores, Match Stats, Quizzes, Polls & much more.
