Common Causes of Dry Eye

Dry eye is a common condition that affects over 4 million people in the United States of America. If you are one of these people suffering from dry eyes, you know how dry eye symptoms can become a nuisance in your daily life. Beverly Hills dry eyes can cause discomfort, itching, and even vision problems, making it challenging to carry out your daily chores.

Dry eye occurs when the eyes don’t produce enough tears to lubricate and nourish them. If left untreated, dry eyes can lead to more serious eye problems, such as eye infections and vision loss.

Here are common causes of dry eye:


As a person ages naturally, their eyesight and eyes undergo several changes. One of these changes is a reduction in tear production which can lead to dry eye. The decrease in tear production is often due to hormonal changes that occur as you age. According to the studies, most adults over 65 suffer from dry eyes, which impacts their sensitivity to light and their ability to drive at night.


Allergies can also trigger dry eye. One of the primary causes of dry eyes caused by allergies is the use of oral antihistamines. These drugs lessen the quantity of tears that are naturally produced. Furthermore, allergic conjunctivitis, which results in swelling and irritation of the eye tissue, can make the body produce ineffective tears.

Environmental factors

Living in a dry or windy environment can make your eyes dry out more quickly. This is because the wind and dry air can evaporate your tears before they have a chance to lubricate your eyes properly. Additionally, spending a lot of time in front of a computer screen or using a smartphone can also cause your eyes to become dry.

Vitamin A deficiency

Vitamin A promotes eye health. Foods rich in vitamin A include carrots, spinach, eggs, salmon, broccoli, and peppers.

Dry eyes and other visual problems, such as night blindness, might result from a diet low in these vitamin-rich foods. A blood test can be used to identify vitamin A deficiency. You can also inquire with your doctor about utilizing eye drops that contain vitamin A, although they are not frequently used for treating dry eyes.


Blepharitis is an eye condition that causes the eyelids to become inflamed. This can cause your eyelids to become red, swollen, and itchy. The inflammation can also interfere with the production and distribution of your tears, leading to dry eye.

Although there is no known cure for this condition, you can lessen inflammation by placing a warm compress over your closed eyes for a few minutes and cleansing your eyelids with baby shampoo. Consult your doctor if your symptoms don’t go away, and inquire about using antibiotic eye drops as a remedy.

Sjögren’s syndrome

Sjögren’s syndrome is an autoimmune disease that causes white blood cells to attack your salivary and tear glands, lowering tear production. You can use prescription lubricating eye drops to treat this condition. Also, your doctor may prescribe a steroid eye drop.

In addition, people with autoimmune diseases like rheumatoid arthritis and lupus are at a higher risk of developing dry eye. People with diabetes, thyroid problems, and other hormonal imbalances can also be more susceptible to dry eye.
