Viagra, or sildenafil, can cause several types of vision problems. The most common is a temporary blue-tinted vision. This usually resolves quickly once the medication wears off. However, more serious issues, though rare, may occur.
Non-Arteritic Anterior Ischemic Optic Neuropathy (NAION)
NAION is a sudden decrease in vision, often affecting one eye. It’s caused by reduced blood flow to the optic nerve. While a link between Viagra and NAION exists, it’s primarily observed in men with pre-existing risk factors for NAION, such as high blood pressure, diabetes, or high cholesterol. If you experience sudden vision loss, seek immediate medical attention.
Retinitis Pigmentosa
Men with retinitis pigmentosa, a hereditary eye disease, should exercise extreme caution when considering Viagra. The medication may exacerbate existing vision problems in individuals with this condition. Consult your ophthalmologist before using Viagra if you have retinitis pigmentosa.
Other Visual Disturbances
Less frequently reported side effects include light sensitivity, blurred vision, and difficulty distinguishing colors. These effects are generally mild and temporary. If these symptoms persist or worsen, consult your doctor. Remember to always discuss any medications you’re taking, including Viagra, with your physician or ophthalmologist to minimize potential risks.
