Vision can change overnight due to several factors, including fluctuations in fluid levels in the eye, temporary dryness, or changes in blood sugar levels, particularly in individuals with Diabetes. Allergies or irritation can lead to swelling or redness, affecting clarity. Additionally, sleep position and the use of contact lenses can also contribute to temporary vision changes. If vision changes persist, it's essential to consult an eye care professional.
