Pregnancy brings about various changes in the body, including changes in vision. While some women may experience minimal vision changes, others may notice significant shifts in their eyesight during pregnancy. In this in-depth article, we will explore the reasons behind these vision changes, the different types of vision changes that can occur, and how pregnant individuals can manage and address these changes.
Hormonal Influences on Vision
During pregnancy, the body undergoes numerous hormonal changes to support the growth and development of the fetus. These hormonal fluctuations can impact various parts of the body, including the eyes. One hormone that plays a significant role in vision changes during pregnancy is progesterone.
Progesterone is a hormone that rises throughout pregnancy and contributes to various physiological changes. It affects the thickness and shape of the cornea, the clear front surface of the eye. This alteration can lead to refractive changes, meaning that the eye's focusing ability is affected, leading to blurry or distorted vision.
Additionally, hormonal changes during pregnancy can also affect the production of tears and the lubrication of the eyes. This can result in dry eyes, causing discomfort and irritation.
Common Vision Changes during Pregnancy
Refractive Changes: As mentioned earlier, the hormonal fluctuations during pregnancy can cause changes in the shape and thickness of the cornea. These changes can lead to refractive errors such as myopia (nearsightedness) or hyperopia (farsightedness). Pregnant individuals who previously did not require corrective lenses may find themselves needing them during pregnancy. Conversely, those who already wear glasses or contact lenses may notice shifts in their prescription.
Blurred Vision: Blurred vision is a common complaint during pregnancy. It can be caused by both hormonal changes and fluctuations in blood sugar levels. High blood sugar levels, which can occur in gestational diabetes, can lead to temporary vision changes. If you experience sudden or severe blurred vision, it is essential to consult with your healthcare provider promptly.
Dry Eyes: Hormonal changes during pregnancy can affect tear production, leading to dry eyes. Dry eye symptoms include itching, burning, redness, and a gritty sensation in the eyes. Using artificial tears and avoiding environments with dry air or excessive screen time can help alleviate dry eye symptoms.
Increased Sensitivity to Light: Some pregnant individuals may become more sensitive to light during pregnancy. This sensitivity, known as photophobia, can make it challenging to tolerate bright lights, sunlight, or even fluorescent lighting. Wearing sunglasses with UV protection and reducing exposure to harsh lighting can provide relief.
Puffy Eyelids: Fluid retention is a common occurrence during pregnancy, and it can also affect the eyelids. Puffy eyelids often accompany facial swelling and can temporarily affect vision. Applying cool compresses and avoiding excessive sodium intake can help reduce eyelid puffiness.
Gestational Diabetes and Retinopathy: Pregnancy can increase the risk of developing gestational diabetes, a condition characterized by high blood sugar levels during pregnancy. Uncontrolled gestational diabetes can lead to diabetic retinopathy, a condition that affects the blood vessels in the retina. Regular eye exams are crucial for pregnant individuals with gestational diabetes to monitor the health of their eyes.
Managing Vision Changes during Pregnancy
Although vision changes during pregnancy can be bothersome, most of them are temporary and will resolve after giving birth. However, there are several steps pregnant individuals can take to manage and alleviate these changes:
Regular Eye Exams: Schedule regular eye exams during pregnancy to monitor any significant changes in your vision and ensure the health of your eyes. Inform your eye doctor about your pregnancy and any specific concerns you may have. Regular eye exams are essential, especially for individuals with pre-existing eye conditions or gestational diabetes.
Manage Dry Eyes: Use preservative-free artificial tears to moisturize the eyes and alleviate dryness. Avoid excessive screen time and maintain a healthy level of humidity in your environment. Remember to blink regularly while using digital devices to prevent further eye dryness.
Wear Corrective Lenses: If you experience refractive changes during pregnancy and require corrective lenses, consult with your eye doctor for an updated prescription. Wearing properly fitted glasses or contact lenses can help improve vision clarity and reduce discomfort caused by blurry vision.
Practice Eye Hygiene: Keep your eyes clean and free from any potential irritants. Avoid rubbing your eyes excessively to prevent infection or exacerbation of dry eye symptoms. Wash your hands thoroughly before touching your eyes to reduce the risk of eye infections.
Protect Your Eyes from UV Rays: Wear sunglasses with 100% UV protection to shield your eyes from harmful ultraviolet rays. UV protection is especially crucial during pregnancy, as the eyes may be more sensitive to light.
Maintain a Healthy Lifestyle: Proper nutrition, regular exercise, and adequate hydration can contribute to overall eye health during pregnancy. Incorporate foods rich in antioxidants, omega-3 fatty acids, and vitamins A, C, and E into your diet to support healthy vision.
When to Seek Medical Attention
While most vision changes during pregnancy are normal and temporary, it is important to recognize when symptoms may indicate a more severe issue. If you experience any of the following, consult with your healthcare provider or eye doctor immediately:
Sudden and significant vision loss
Severe and persistent blurred vision
Flashing lights or sudden onset of new floaters
Eye pain or redness
Double vision
Changes in peripheral vision
Seeing halos around lights
These symptoms may indicate conditions that require prompt medical attention, such as preeclampsia, gestational diabetes complications, or retinal detachment.

Pregnancy is a time of joy and excitement, but it can also bring about changes in vision. Understanding and managing these vision changes are essential for the well-being of pregnant individuals. By staying informed, scheduling regular eye exams, and adopting healthy habits, individuals can navigate the temporary vision changes during pregnancy with confidence. Remember, while most vision changes during pregnancy are normal, it is crucial to seek medical attention if you experience any sudden or severe symptoms. Stay proactive and prioritize your eye health to ensure a smooth pregnancy journey.
