Can Toenail Fungus Spread to Eyes?

If fungus can spread to any part of the body, can it also spread to the eyes?

Just the thought of fungus spreading to the eyes scares us, doesn’t it?

Many people wonder if the toenail fungus can spread to the other parts of the body. They can often worry about their appearance as the toenail fungus makes the toenail looks ugly sometimes. Also, it is very dangerous if the fungal infection spreads in the blood. Many people just think of it as a normal infection and leave it untreated for weeks until one day when the toenail appears to be totally discolored. If you notice a sudden change in the color of your toenails, consult your doctor. Also, if your toenails have become brittle, patchy, black or brown, you have to rush to your doctor as soon as you can.

If you’re wondering whether toenail fungus can spread to eyes, the answer is – ‘it is very rare, but the chances do exist.’ The fungi that exist on the toenails are very contagious and can easily get to the bloodstream. When in the bloodstream, it can reach any part of the body.

Let us dive deeper into how the toenail fungus can spread to the eyes:

Fungi prefer warm and moisturized areas of the skin. Since eyes are always moisturized, they can be the perfect place for fungi. As fungi can be transformed by anything or anyone such as cats, dogs, towels, clothes, soaps, etc, it is possible for the fungi to come in contact with the eyes externally. It is very important for you to know and understand that a fungal infection or mycosis arises when fungi pass the top layer of the skin, hair or nails.

Let me tell you:

  • Toenail fungus is treatable.
  • It is contagious and can spread anywhere, including eyes.
  • However, the spreading of toenail fungus to eyes is a very rare thing.

If you have a toenail fungus, you can do the following to prevent it from spreading to your eyes:

  • Make sure you never use the towel you used to wipe your feet to wipe your eyes.
  • If you wear contact lenses, do not touch them after you touch your feet.
  • Keep your hands clean and wash them always after you touch your feet.
  • Try to strengthen your immune system to avoid the fungus entering your bloodstream.
  • Eat healthy food that can cure or relieve you from the symptoms of toenail fungus.
  • Always wear socks or cover your feet.
  • Keep your feet dry and let them breathe to cure them.
  • If your eyes feel itchy, contact the doctor right away.

As mentioned above, toenail fungus being spread to the eyes is absolutely rare. But… Prevention is better than cure.

Signs that you have contracted a fungal eye infection:

The people who have had exposures that put them under a risk to develop a fungal eye infection should look out for the symptoms that are similar to that of the other eye infections.

Fungal eye infection can appear anywhere from several days to several weeks after the fungi enter the eye. When the fungi start spreading, it can cause:

  • Pain in the eyes
  • Redness in the eyes
  • Blurred vision
  • Excessive tearing
  • Eye discharge
  • Sensitivity to light

If you have candidiasis, there are chances that you already have fungi in your bloodstream. You must make sure that your immune system is not affected by it at all.

There are many types of fungal eye infections like:

  • Fusarium – This fungus lives in the environment and not on a part of toenail fungus.
  • Aspergillus – This is a common fungus that lives in indoor and outdoor environments.
  • Candida -This is a type of yeast that lives on human skin and on the mucous membrane. There is a possibility of this fungus spreading from the toenail to the eyes.


To check if you have contracted a fungal infection in your eyes, the doctor will examine your eye closely and take a small sample of your eye tissue or fluid to test it in a laboratory. However, if you’re someone:

  • Who has had recent eye surgery, eye injury or a chronic eye disease involving the surface of the eye
  • Or whose eyes come in contact with medical products
  • Or, who has fungal bloodstream infection, like candidemia,

Can have a fungal eye infection.

To sum up…

If you want to make sure that the toenail fungus that you or someone else has doesn’t spread to your or their eyes, you must take proper measures to treat the toenail fungus itself. Also, make sure that your eyes are far away from the things that have touched the infected toenails. Though the chances of transmitting toenail fungus to the eyes are rare, we shouldn’t take chances. Get your toenail fungus treated at the earliest. Also, get a prescribed list of anti-fungal ointments and medicines to treat the toenail fungus immediately.
