Avoid Allergens
To deal with blurry vision due to allergies, the best strategy is to avoid allergens. The first step is to identify which may trigger an allergic reaction and take proper approaches to prevent them. For instance, if dust is the main culprit, it is important to clean your living space regularly to prevent them from accumulating and affecting your eyes during sleep. For outdoor allergens, always keep the windows close and use an AC system that would filter them out. If necessary, ask your healthcare provider for prescription antihistamine eye drops to manage the symptoms. [9]
