Dry eyes are a condition in which there is insufficient tear production or an unstable tear film. This can lead to irritation, redness, and a sandy, gritty feeling. It can also cause difficulty wearing contact lenses, making them feel uncomfortable.

Symptoms of dry eyes can also include:

  • The sensation that there is something in your eye even when there isn’t
  • Burning or stinging
  • Watering eyes
  • Red, swollen, or crusted eyelids

Tears are made up of three main components: water, oils, and mucus. The most abundant element is water, which helps keep the eye’s surface lubricated and provides a medium in which substances can be dissolved.

Oils are produced by tiny glands located in the eyelids. These help to reduce evaporation and keep the surface of the eye smooth. If you don’t have enough of this oily substance in your eye, tears will tend to evaporate too fast, even if they are abundant enough. These poor quality tears occur if the glands that make the oily substance are not functioning correctly. Mucus helps to spread the tears over the eye’s surface and trap dust and other particles. Together, these three substances help to keep the eye clean and healthy.

Why do you get dry eyes?

Dry eye occurs when the eyes do not produce enough tears or when the tears are not of the right consistency to keep the eyes lubricated. This can lead to discomfort, redness, and blurred vision. Some causes of dry eye include wind, smoke, and air pollution; medications that cause decreased tear production; long hours of screen use, and ageing.

In severe cases, this condition can damage the cornea. Dry eyes are a common problem, especially among older adults.

What if you wear contact lenses?

Contact lenses are a great way to improve your vision, but they can also cause problems if not used properly. One of the most common issues is dry eyes. When you wear contacts, your tears can evaporate more quickly, making your eyes irritated and uncomfortable.

The contact lens itself makes the user prone to dry eyes as it can partially block oxygen from flowing to the eyes. Healthy eyes need a good supply of oxygen from the environment. Even though your eyes can get dry whether you wear contact lenses or not, it is incredibly uncomfortable when you do wear contacts.

There are a few things you can do to help prevent this problem:

  • make sure you clean your lenses regularly
  • avoid touching your contacts with unwashed hands
  • keep the lens case clean
  • replace them according to the manufacturer’s instructions
  • make sure the lenses you use fit your eye well and try different types if they don’t
  • use eye drops and gels as regularly as you need to keep your eyes lubricated
  • take breaks from wearing your contacts throughout the day to give your eyes a chance to rest
  • take screen breaks

If you follow these tips, you should be able to wear your contacts without any trouble.
