Erectile dysfunction (ED) can be a difficult and overwhelming problem for many men. Fortunately, there are medications available that can help. One of the most popular and commonly used pills is Viagra (sildenafil).

However, while the drug may help with erections, it can also have some unwanted side effects, including vision problems.

What is Viagra (Sildenafil)?

Viagra is a medication used to treat erectile dysfunction. It works by relaxing the blood vessels and allowing more blood flow to the penis. This increased blood flow can help to achieve and maintain an erection.

Viagra is typically taken 30 minutes to an hour before sexual activity. It can be taken with or without food, but it should not be taken more than once a day.

How Does Viagra Affect Sight?

One of the potential side effects of Viagra is vision changes. These changes can include:.

Blurred vision
Sensitivity to light
Difficulty distinguishing between blue and green colors

The exact reason that Viagra can cause these vision changes is not fully understood. However, it is believed to be related to the way that the medication affects the blood flow to the eye.

In rare cases, men taking Viagra may experience more serious vision changes, such as:.

Vision loss in one or both eyes
Sudden decrease in vision
Non-arteritic anterior ischemic optic neuropathy (NAION)

If you experience any of these vision changes while taking Viagra, you should stop using the medication and seek medical attention immediately.

Who is at Risk for Vision Problems While Taking Viagra?

While vision changes are a potential side effect of Viagra, they are not common. According to the manufacturer, only around 3% of men taking Viagra develop vision problems. However, the risk may be higher for certain groups of men, including:.

Men over the age of 50
Men with pre-existing eye conditions, such as macular degeneration or glaucoma
Men with diabetes
Men who have previously experienced vision problems while taking Viagra or other similar medications

What Should You Do if You Experience Vision Problems While Taking Viagra?

If you experience vision changes while taking Viagra, you should stop using the medication and seek medical attention immediately. Your doctor may recommend that you switch to a different medication to treat your erectile dysfunction.

In some cases, the vision changes may be temporary, and your vision may return to normal once you stop using the medication. However, in rare cases, the changes may be permanent.

What Are the Other Side Effects of Viagra?

In addition to vision changes, Viagra can also cause other side effects. These can include:.

Headache
Flushing
Indigestion
Nasal congestion
Urinary tract infections
Dizziness
Nausea
Back pain

If you experience any of these side effects while taking Viagra, you should talk to your doctor. They may recommend adjusting your dose or trying a different medication.

Always follow the instructions provided by your doctor or pharmacist
Do not take more than the recommended dose of Viagra
