Tadact 20 mg contains tadalafil, which is a phosphodiesterase type 5 (PDE5) inhibitor used to treat erectile dysfunction (ED) in men. It is not typically associated with causing changes in vision to the same extent as some other medications in the same class, such as sildenafil (Viagra).

However, it's essential to be aware that some individuals may experience mild and temporary vision-related side effects while using tadalafil or similar PDE5 inhibitors. These side effects can include:

Blurred Vision: Some people may notice a temporary blurring of vision while using tadalafil. This effect is usually mild and transient, resolving on its own without any long-term consequences.

Color Tinge: In rare cases, tadalafil can cause a slight change in color perception, such as a blue or green tinge to objects. This effect is typically mild and temporary.

Light Sensitivity: Tadalafil Tadact 20 mg may also increase sensitivity to light for some individuals, leading to a sensation of glare or discomfort in brightly lit environments.

Rare Vision Changes: While uncommon, some people may experience more severe vision changes, such as changes in visual acuity, difficulty distinguishing between colors, or changes in peripheral vision. These effects are rare and should be reported to a healthcare provider immediately if experienced.

It's important to note that these vision-related side effects are generally mild and tend to occur infrequently. Most people using tadalafil do not experience significant changes in vision.
