What is Blind Spots?

Blind spots are areas in our vision that are not visible, usually located near the nose or center of vision. They occur when the optic nerve and blood vessels pass through the back of the eye, blocking light from reaching photoreceptors in this area. Blind spots can be a nuisance and affect day-to-day activities such as driving, reading and more.One of the most common causes of blind spots is age-related macular degeneration (AMD). This condition occurs when the macula, a part of the retina located at the back of your eye, deteriorates over time. When AMD affects both eyes, it can lead to permanent blind spots in both central and peripheral vision. Other causes include glaucoma, cataracts and retinal detachment.Having a blind spot can potentially lead to dangerous situations while driving because it makes it difficult to judge distances between cars or read road signs properly. It is important to get checked by an optometrist if you notice any changes in your vision such as dark patches or wavy lines that indicate a problem with your eyesight. Your optometrist may recommend treatments such as corrective lenses or surgery to help improve your sight and reduce your risk for accidents resulting from visual impairment. In addition to medical treatments, there are lifestyle adjustments you can make that may reduce symptoms associated with blind spots: -Wear sunglasses outdoors on sunny days: UV exposure can worsen existing conditions like AMD that cause blind spots -Avoid smoking: Smoking increases your risk for developing AMD, which is one cause of blindness -Eat foods rich with antioxidants: Foods like spinach, kale and blueberries contain vitamins A & C which help protect against free radical damage that can contribute to developing AMD -Be aware of changes in light intensity: If you start noticing dark patches around objects when going from bright to dim lighting conditions; this may indicate a problem with your vision -Visit an optometrist regularly for checkups: Even if you think everything looks fine; regular checkups will ensure any potential problems are caught early on before they become serious Blind spots can interfere with everyday activities if left untreated so it’s important to pay attention to changes in your vision and seek treatment immediately if needed.
