Tree Pollens And Eye Allergies
Eye puffiness and swelling are common symptoms of allergic conjunctivitis, usually with itchy, and red eyes, a burning sensation, and a clear, watery discharge. People that suffer from tree pollen allergies may assume that trees with colorful flowers like apple or cherry trees will trigger their symptoms. However, flowering trees usually have bigger, stickier pollen that doesn’t blow in the wind or cause symptoms. In the United States, Spring allergies usually start in February and end in early summer. Seasonal allergies can occur at almost any age, and they usually develop around the age of 10 and peak in the early 20s. Flowers, bushes, and trees, the beauty of Spring, and the potential impact on our eyes.
March 2023 through June 2023 is tree pollen season. June, July, and August are usually when the grass pollens are high, sometimes into September in a warm year. People suffering from eye allergy may experience blurred vision or “sticky eyes” (a mucus buildup in the eyes and the corners of the eyelids). Grass and ragweed pollens are the most common cause. In 2018 a study revealed that hay fever alone causes nearly four million missed workdays each year, costing businesses more than 700 million dollars.
The Pollination Cycle
Tree pollination begins earliest in the year then there is grass pollination later in the spring and summer and ragweed in the late summer and fall. The allergy cycles are:
- Cycle 1: Winter and Early Spring (January to early April)
- Cycle 2: Late Spring and Early Summer (late April to July)
- Cycle 3: Late Summer and Fall (August to December).
We are in the last month of Cycle 1. The main reason for these pollens during this period is due to plant pollens spreading from plant to plant by the insects that visit them (entomophilous plants). Therefore, most of our pollen exposure is due to pollen in the air outdoors, and thus our allergies are due to wind-pollinated plants. Many times we cannot see it in the air and often do not know when the season starts until symptoms begin.
The wind is the driver for pollinating trees. Mold spores contribute to spring allergies during this period. However, they are most annoying in the fall. It is important to note that cross-reactivity between tree pollens is minimum. Some trees are inherently the same and the pollens are somewhat similar. Therefore, many tree pollens have unique features that make it difficult to create a single treatment for tree pollen allergy.
Seasonal allergies, also known as hay fever or allergic rhinitis, are allergy symptoms occurring only during certain times of the year which is when allergens like mold spores and different types of pollen from trees, grasses, or weeds are present in the air.
Causes of Eye Allergies
- Pet dander
Trees That Cause The Most Symptoms
- Box elder
Your immune system cells will treat allergens like mold spores or pollen as a threat. The immune system reacts by releasing substances like histamine into the bloodstream to fight them. When releasing histamine into the bloodstream to fight them it can cause:
- Runny or stuffy nose (nasal congestion)
- Itchy, watery eyes
- Sinus congestion
- Sore throat
- Post-nasal drip
- Itchy nose or throat
- Itchy mouth or skin
- Fatigue(often due to poor-quality sleep as a result of nasal congestion)
Itchy, watery eyes and other symptoms like swollen are signs that you are allergic to something. These are usually small/foreign particles or substance like dust that gets into your eyes. Your body’s natural defense system releases histamine to fight these foreign substances. This results in an eye allergy which occurs when your immune system reacts, allergic conjunctivitis, to the presence of foreign like pollen and or mold or dust. Allergic conjunctivitis can cause eyelid discomfort and swelling. Not all people experience lid inflammation and other corneal irritation and scarring.
Ways To lesson The Impact Of Pollens
- Stay inside when the count is high
- Stay inside when it is windy and warm
- Go outside at the right time
- Know which pollens you are allergic to and respond accordingly
- Start your medication regimen early
- Close windows and doors
- Keep your home clear of dust and allergens
- Change furnace filters frequently
- Shower at night
- Premedicate with an antihistamine or put on a pollen mask before going outside
- Manage pet dander
- Beware of mold
