Video - What Causes Astigmatism?

Click the video above to learn what is the cause of Astigmatism. It is most commonly caused when the shape of front surface of your eye (called the cornea) is not perfectly round (like a baseball)  but, it is more oblong shaped (like a football).  When this oblong shape is located on the cornea then it is called “Corneal Astigmatism”.  Less often, the lens inside your eye (located right behind the colored part of your eye called the iris) can also be oblong shaped.  This is called “Lenticular Astigmatism”.

Most commonly, people are born with this oblong shape to their eyes and often it can become a bit worse as time goes on.  More rarely – astigmatism can be induced by a trauma to the eye.

Astigmatism causes a blur and distortion to your vision – for both distance and near objects.  The higher the amount of astigmatism – the worse the blur and distortion will be. Astigmatism can be corrected with a variety of options – glasses, contact lenses (called toric or astigmatic contacts) and laser vision surgery.

TO SEE A FOX NEWS VIDEO ABOUT EYE CANCER AND PROTECTION WITH SUNGLASS WEAR

The sun can cause aging changes to your skin… and also to your EYES.

Macular Degeneration and Cataracts are aging changes that can be brought on earlier in your life by exposure to the sun its ultraviolet (UV) radiation.  Wearing sunglasses with good UV protection can be like wearing sunscreen for your eyes.

There are many different types of eye cancer that can affect any part of the eye.  A patient can get cancer on the Eyelids, the Conjunctiva (the “skin” over the white of your eye), the Iris (the colored part of your eye), the Optic Nerve (the nerve from the eye back to the brain), the Retina (the nerve layer inside your eye – responsible for your vision), the Choroid (the blood vessels beneath the retina) and more.

The types of cancers that usually affect the skin (aka on the eyelids….basal cell carcinoma, squamous cell carcinoma, melanoma etc.. ) can be the same types of cancers that particularly thrive in sunlight and UV exposure – just like any other type of skin cancer.

EVERYONE (including children) should be wearing sunglasses with UV protection any time they are outdoors. People who are particularly vulnerable are those with with blue eyes, light complexions, work outdoors, have had any PREVIOUS skin cancer or who are taking any medications that make them more light sensitive.

Routine yearly eye examinations are the KEY to early detection and treatment for any types of eye cancer and any other type of eye disease
