Sildigra 100 mg, which contains sildenafil citrate (the same active ingredient as Viagra), can affect your vision in some cases. Vision-related side effects are known to occur with sildenafil and other PDE-5 inhibitors (phosphodiesterase type 5 inhibitors), although they are rare and typically mild. Potential Vision Side Effects of Sildigra 100 mg: Blurred Vision: Some users may experience temporary blurred vision shortly after taking the medication. This is usually not serious and fades as the drug's effects wear off. Color Disturbances: Sildenafil may cause changes in color perception, such as seeing a blue tint or difficulty distinguishing between blue and green. This effect is related to the drug’s influence on certain enzymes in the retina. Increased Sensitivity to Light: Some individuals may experience photophobia (sensitivity to light), making bright lights uncomfortable after taking sildenafil. Vision Loss (Rare): In very rare cases, Sildigra 100 mg has been linked to non-arteritic anterior ischemic optic neuropathy (NAION), a condition that can cause sudden vision loss in one eye. This is considered a serious medical condition, and if you experience sudden vision changes or loss, you should seek immediate medical attention. Who is at Greater Risk? Pre-existing eye conditions: People with conditions like retinitis pigmentosa, optic neuropathy, or a history of eye problems may be at a higher risk of experiencing visual side effects. Older adults: Men over 65 may be more prone to side effects, including vision changes. Heart problems: If you have a history of heart disease or vascular problems, there may be a higher risk of side effects, including those related to vision. What to Do if You Experience Vision Problems: Mild Effects: If you experience temporary blurry vision or color changes, these side effects typically resolve as the medication leaves your system, which usually takes a few hours. Serious Effects: If you experience sudden vision loss, persistent vision changes, or other severe symptoms (such as eye pain or seeing flashes of light), seek immediate medical attention. Vision loss due to NAION requires prompt evaluation.
