What is the difference between artificial tears and prescription medications for dry eye?

Artificial tears are the most common treatment for mild dry eye. They are over-the-counter eye drops that work to lubricate the eye and alleviate symptoms [4]. Prescription medications for dry eye, such as cyclosporine (Restasis) or lifitegrast (Xiidra), are eye drops prescribed by a doctor for more severe cases, aimed at helping the eye produce more natural tears [4].

Artificial Tears: When and How to Use Them?

Artificial tears are used as a first-line treatment for dry eye and are designed to compensate for the lack of moisture on the eye's surface. These drops mimic the function of natural tears in maintaining eye moisture and protection [1]. Artificial tears are available in various formulations, and doctors may recommend preservative-free types for individuals who need to use them frequently, as preservatives can cause eye irritation with excessive use.

Prescription Medications: For More Severe Cases

If dry eye is more severe and the condition does not respond to artificial tears, an ophthalmologist may prescribe medications such as cyclosporine or lifitegrast. These medications are eye drops that help the eyes produce more tears [4]. These medications should not be used without consulting an ophthalmologist, as their use requires an accurate diagnosis and medical supervision to ensure their effectiveness and safety.

Additional Dry Eye Treatment Options

In addition to eye drops, there are other treatment options for dry eye. These may include lifestyle changes, such as avoiding smoke, wind, and air conditioning, using a humidifier, limiting screen time, wearing protective sunglasses, staying hydrated, and getting enough sleep [4]. In some cases, a doctor might suggest placing special plugs (called punctal plugs) in the tear ducts to help keep tears in the eyes for longer [4]. In rare cases, if dry eye is caused by loose lower eyelids, a doctor may suggest surgery to correct the eyelids and help tears remain in the eye [4].

When Should You Consult a Doctor?

You should consult a doctor if you experience persistent dry eye symptoms that do not improve with the use of artificial tears, or if the symptoms are severe and affect your vision [4]. You should also see a doctor if you notice any purulent eye discharge or if the eyelids stick together, as these may be signs of an infection such as conjunctivitis [3]. An ophthalmologist can perform a comprehensive eye exam to diagnose the cause of dry eye and determine the best treatment plan for you [4].
