Doctors and pharmacists will usually prescribe eye drops for allergies which affect the eyes. The key purpose of the eye drops is to lower discomfort as a result of allergies. During an allergic reaction, the eyes adversely respond to substances that the body translates as risks. For this reason, the immune system releases a hormone recognized as histamine. The eyes then turn into inflammed, teary or watery and their colour changes to red. This reaction may be followed by distinct swelling and puffiness around the eyes. Another typical cause of eye allergy is dry eyes. When the eyes become too dry the tear glands tend to overcompensate by producing more tears which outcome in watery eyes.

There are many reasons of allergies and some individuals are more susceptible to particular allergens than some others. The most frequent of these are airborne meaning they spread through the air. Examples consist of pet fur and fluff, pollen grains, dust and some types of mould. There are people who develop eye allergies from bee stings or even from eye drops recommended for allergies. Regular consumers of contact lenses may produce allergies from time to time.

A number of treatment options are available to help reduce eye allergies. Options vary between prescribed medicines and non prescription medicines. Prescription medicines may be an expensive option but they have proven to be more effective than non prescription ones. The main types of medication are; decongestants which work by constricting the eye's blood vessels reducing redness and swelling, antihistamines which suppress the production and action of histamine, anti-inflammatory drugs, eye washes and medicines which have mast cell stabilizers. These medicines are available as pills to be taken orally or as eye drops. The eye drops produce quicker comfort since they are utilized directly to the eyes. During the allergy season when pollen and dust are more prevalent, it may be recommended to use sunglasses while outdoors, keeps the air refresher operating and to make sure the house is free of dirt and pet fur.

The usage of eye drops for allergies depends on the specific medicine even though the recommended dose is 2-4 times per day. The mode of administration is simple. The individual should ensure that the hands are clean 1st. The head is then tilted back with one hand holding the eye open while the other gently pushes the suggested drops into the eye. If the person uses contact lenses, they should be removed earlier to using the eye drops and a period of about 10 minutes should elapse before the contacts are reinserted.

Painful, burning up and discomfort may occur after the use of eye drops. If this persists longer than a few minutes, a doctor should be consulted. Some individuals may encounter taste changes after applying the medicine. Care should be taken not to contaminate the dropper or the eye drop solution since this could lead to eye infections. People with medical conditions like glaucoma or cataracts should inform their doctors before being given eye drops for allergies they might have.
