There are many diseases and associated conditions which can be picked up with an eye test, including glaucoma, cataracts and diabetes. The College of Optometrists in the UK recommends a yearly check for children under 16 and every two years for adults and at SN&N Optico the focus is always on encouraging regular eye exams for good health.


A very common complaint here in the sunny Algarve is Allergic Conjunctivitis:
The two most common types of allergic conjunctivitis are seasonal allergic conjunctivitis (SAC) and perennial allergic conjunctivitis (PAC).

Both are triggered by an immune reaction when you come into contact with a particular substance you are allergic to, leading to symptoms such as itching and sneezing.


Eye allergies often affect the conjunctiva, a clear layer of skin overlying the eyes, which is the same type of skin that lines the inside of the nose; this is why the same allergens (e.g. pollen, grass, dust and pet dander) can trigger the same allergic response in both areas.


The main symptom of eye allergies is itchy eyes and may be associated with redness, watering, a burning sensation, and mucous production and blurring.


Diagnosis of eye allergies are usually made from symptoms and by examining the front of the eyes with a slit lamp (a special microscope) to check for dilated blood vessels, conjunctival swelling and eyelid swelling, all of which are indicative of an allergic reaction.


If you can identify and avoid the particular agent you are allergic to, symptoms will improve dramatically. Unfortunately, this is not always easy or possible! Some of the following treatments can provide relief from eye allergies: applying cold compresses, using artificial tears as needed, allergy eye drops and oral antihistamines. Avoid rubbing your eyes as this can worsen symptoms.


Unfortunately, other than avoidance of the allergens, allergic conjunctivitis cannot be prevented. Although it is an annoying inconvenience and can sometimes make daily activities miserable, no long-term vision loss is to be expected.
