Occasional blurry vision is very common and often caused by simple factors like dry eyes, fatigue, or digital eye strain. To help soothe your eyes, you can try over-the-counter lubricating eye drops, also known as artificial tears (preferably preservative-free). Avoid using redness-relieving drops frequently, as they can worsen irritation over time. Since blurry vision can sometimes stem from other easily correctable issues like a change in your glasses prescription, it is best to visit an eye care specialist for a proper examination before starting any medicated drops. Please seek immediate care if the blurriness is sudden, severe, or accompanied by pain.
