Red-eye is something that can affect many people and significantly hamper their enjoyment of everyday activities, but there are ways to avoid it, one expert has noted.
Dr Chris Purslow, a leading optometrist, explained that the appearance of a so-called 'red eye' is the result of the capillary vessels in the conjunctiva, or white of the eye, becoming dilated and engorged with blood.
This is a common response to irritation or inflammation and the appearance, which is sometimes accompanied with mucus discharge from the eye, is generically referred to as conjunctivitis, or inflammation of the conjunctiva.
"Conjunctivitis can be caused by a number of factors including dry eye, environmental irritation such as swimming pool water, or allergies such as hay fever," she explained.
The impact that hay fever season and red-eye can have on our eyes is significant, but there are steps we can take to combat this, the expert noted.
Dr Purslow noted that hay fever can cause an allergic reaction in the eyes of some people known as allergic conjunctivitis, but there are products available to treat it.
"Eye drops can help to alleviate signs and symptoms. Eye drops, such as ROHTO Dry Eye Relief, can help make the eyes feel more comfortable and relieve sore, itchy eyes," she advised.
The key thing to remember is that people need to avoid environments where any irritation may occur, such as fields and other areas, unless they have hayfever medication, while they should also use any approved products at their disposal to combat any eye irritation, the expert noted.
Recently, News USA pointed out that when irritation occurs, it is always best to remove contact lenses, but this does not mean they can not be worn at all at certain times of the year.
"Prescription eyedrops, pills or allergy therapy can help reduce symptoms, and some companies are working to make contact lenses healthier for allergy sufferers," the source explained.
