Pregnancy often brings various physical changes, including blurry vision. While these vision changes are frequently temporary and harmless, understanding their underlying causes and recognizing when medical advice is necessary is important.
Common Reasons for Vision Changes
Hormonal fluctuations are a common reason for vision changes during pregnancy. These shifts can influence the shape and thickness of the cornea, the clear front surface of the eye. Increased fluid retention, a common pregnancy symptom, can cause slight swelling in the cornea, altering its curvature and leading to temporary blurry vision.
Reduced tear production, also due to hormonal changes, can result in dry eyes. Dryness can make vision feel gritty or scratchy and contribute to blurriness, as a healthy tear film is necessary for clear sight. These vision changes are typically temporary and often resolve within weeks or months after delivery.
When Blurry Vision Signals a Serious Concern
While often benign, blurry vision during pregnancy can sometimes indicate a more serious underlying condition that requires prompt medical attention. Preeclampsia, a condition characterized by high blood pressure and protein in the urine, can manifest with visual symptoms. These symptoms may include sudden blurred vision, seeing flashing lights, auras, or light sensitivity, and they often accompany other signs like severe headaches, swelling in the face or hands, and upper abdominal pain. Preeclampsia typically develops after 20 weeks of pregnancy and can have serious consequences for both the pregnant individual and the baby if left untreated.
Gestational diabetes, a form of diabetes that develops during pregnancy, can also affect vision. Fluctuating blood sugar levels can cause changes in fluid balance within the eye, leading to blurry vision. Unmanaged gestational diabetes can increase the risk of diabetic retinopathy, an eye condition where high blood sugar damages retinal blood vessels. This condition requires careful monitoring and management to prevent complications.
Sudden and significant vision changes, such as new floaters, flashes of light, or a sudden blind spot, could signal a retinal detachment, which is a medical emergency. Any sudden or severe vision changes warrant immediate evaluation by a healthcare provider.
Coping with Pregnancy-Related Vision Changes
Managing vision changes during pregnancy often involves simple, actionable steps, as many alterations are temporary. Resting your eyes frequently can help reduce strain, especially if you spend extended periods focusing on screens. Using lubricating eye drops, also known as artificial tears, can provide relief for dry eyes by moistening the ocular surface. Most lubricating eye drops are considered safe to use during pregnancy, but it is advisable to consult a healthcare provider for recommendations.
It is generally recommended to avoid getting new prescription glasses or contact lenses during pregnancy, as vision typically returns to its pre-pregnancy state after delivery. If wearing contact lenses becomes uncomfortable due to changes in corneal shape or increased dryness, switching to glasses temporarily can be beneficial. Maintaining good hydration by drinking plenty of water can also support overall eye health and help mitigate fluid-related vision issues. Regular prenatal check-ups are important for discussing any vision concerns, allowing healthcare providers to monitor for more serious conditions.
