Allergies: Put the Spring back in your step!
Just like any other allergic reaction, eye allergies are caused by a misfiring of the immune system. The body’s natural defense mechanism reacts to things that aren’t really harmful (like pollen) and releases a chemical called histamine, which causes swelling and inflammation. The blood vessels in the conjunctiva (clear membrane on the surface of the eye)swell and the eyes become red. Sometimes the eyelids also become swollen, and there might be some light sensitivity. Often the eyes water and there may be some stringy discharge or mucous in the tears. A big giveaway for ocular allergy is the itching–and children especially want to rub their eyes or blink a lot! There are many allergy relief products out there. Some of the same oral medicines that you use for nasal allergies also work for eye allergies (ask your GP or pharmacist which option is right for you).A cold, damp facecloth can provide some temporary relief. Taking your contact lenses out can also help alleviate some of the irritation. And don’t rub your eyes, no matter how much they itch! It will only make the irritation worse. Sometimes eyedrops will be the most effective for itchy, watery eyes–but not all allergy eye drops are created equal. Some eyedrops (called decongestants, or ‘anti-red’ drops) should not be used for more than a few days at a time, and can cause a rebound redness if used too frequently. Some eyedrops area topical lubricant(artificial tears), which can be used to soothe the eyes and flush out any antigens (e.g. pollens)that the body is reacting to. Some eye drops work over a longer time period, and the effects last longer, so are best used before you know your symptoms will hit. These are often combined with an anti histamine to relieve the itch quickly and will require a prescription.
