Yes, dry eyes can cause double vision.

Dry eyes occur if you’re unable to produce enough tears or they evaporate too quickly. This can alter how light enters the eye, causing you to see two images, also known as double vision.

Double vision can worsen if you are overworking your eyes from activities like prolonged reading or driving, as this can cause your eye muscles to strain.

You can typically treat dry eyes at home through lifestyle measures, such as:

  • taking regular breaks away from screens, such as your computer, TV, and phone
  • using a humidifier to stop the air in your home from getting dry
  • ensuring you’re getting enough quality sleep each night
  • switching to glasses to rest your eyes if you wear contact lenses
  • staying hydrated

Dry eyes can also be treated using over-the-counter (OTC) eye drops, also known as artificial tears. They are typically only recommended for mild dry eyes and can help provide quick relief.

If your dry eyes are severe, then a healthcare professional may suggest a prescription medication, such as cyclosporine (Restasis) or lifitegrast (Xiidra). These medications can help you produce more tears.

If you still have dry eyes or they worsen even when using OTC tear drops or prescription medication, it’s important to speak with a healthcare professional.

They can take a closer look at your eye health and check for any underlying conditions that may be contributing to your symptoms.
