Eye Care for Your Life
Dry eyes are a common problem, affecting up to one third of the population, and increasing with age to affect as many as 70% of seniors.
Your eyes are constantly producing tears, even when you aren’t aware of it. They provide moisture and lubrication for the surface of your eyes to help you see and to keep your eyes comfortable.
What is a tear?
A tear is a mix of:
What are the symptoms of dry eye?
Dry eye symptoms may include any of the following:
Sometimes, dry eyes create too many tears. This confusing condition is called reflex tearing. It happens because the lack of moisture irritates your eye. This sends a distress signal through your eye nerves asking for more lubrication. Your body sends a flood of tears to try to protect your eyes, much as when you get sand in your eye and it runs. But these tears are mostly water, so they can help wash away debris, but they can’t coat your eye surface like regular tears.
Causes and Risk Factors
What are the causes of dry eye?
Dry eye can be a temporary or chronic condition. It can be caused by:
How is dry eye treated?
Our doctors will first determine the cause of your symptoms. Once the diagnosis is made, there are several approaches to relieve the symptoms.
If dry eye results from taking a medication, your doctor may recommend switching to a medication that does not cause the dry eye side effect.
If contact lens wear is the problem, your eye care practitioner may recommend another type of lens or reducing the number of hours you wear your lenses. In the case of severe dry eye, you may be advised not to wear contact lenses at all.
Changes in your environment can be very helpful. In dry climates, a humidifier can reduce symptoms. Lowering the height of your computer monitor will reduce eye surface exposure. Avoid direct exposure to heating or air conditioning vents, and take a break every twenty minutes from reading, or staring at a computer.
Ocular Lubricants and Ointments
The most common first line of treatment is artificial tears and ointments. Most of these are available over the counter. No one product is right for everyone, so you may have to try a few to find the one that works best for you. They are available in increasing thickness, so your choice depends somewhat on the severity of your condition. Your eyes may dry out primarily when you are asleep, so you may find relief in using drops first thing upon awakening, or by using an eye ointment when you go to sleep.
Prescription Eye Drops
There are two prescription eye drops that can help boost tear production. Cyclosporine, also known as Restasis, an anti-inflammatory medication, and Lifitegrast, or Xiidra, can increase basic tear production, and reduce symptoms of dry eye. It may take two to six months of twice-a-day dosages for the medication to work. In some cases of severe dry eye, short term use of steroid eye drops that decrease inflammation is required.
Other Medications and Nutrition
Other medications can be formulated to treat persistent dry eyes. Adding fish oil or Omega-3 fatty acids to your diet can also help. The use and dosage of nutritional supplements and vitamins should be discussed with your primary medical doctor.
There are methods that allow both natural and artificial tears to stay on your eye longer. Each eyelid has a punctum— a little opening that drain tears away from the eye.
Punctal plugs are painlessly inserted into the puncta to partially or completely block the “drainpipe,” through which tears usually go from your eye into your nose, allowing more tears to be available to the eye. For people who have not found dry eye relief with drugs, punctal plugs may help. They are reserved for people with moderate or severe dry eye.
