My name is Jamie Turner and when I turned 22, I started to form a horrible case of acne. I used every cleanser and lotion I could find and I even asked my physician for a topical steroid cream to clear up the zits on my face. After six months of treatment, my physician completed a blood test that concluded that a hormone imbalance was causing my acne. I started on therapy to control the amount of estrogen my body produced. The therapy along with a good diet and exercise regimen helped to clear up my acne. I am sharing my story, because acne is not just a condition that affects teenagers. It can affect adults at any age, and it can cause a great deal of embarrassment. Don't let your acne go untreated. Read my blog instead and learn about both natural and medical treatments that can help you.
If you experience headaches, nausea and other symptoms every time you expose your eyes to bright holiday decorations and lights, you may have light-sensitive eyes. An eye doctor can examine your eyes and prescribe eyeglasses with special light filters in the lenses to improve your condition. Until you see an eye doctor or ophthalmologist for treatment, keep in mind the information below.
Why Do You Have Light-Sensitive Eyes?
Your eye doctor defines light-sensitive vision as photophobia. The severity of photophobia varies from person to person, and produces different symptoms because of this variance in light-sensitivity. For example, some people experience sensitivity to all sources of light and develop severe migraines when exposed to it. Other people have problems viewing bright lights, such as those used in seasonal decorations, and develop mild headaches or nausea. Yet, there are some people who have past or current histories of migraines, which can lead to light-sensitivity.
How Can Migraines Cause Photophobia?
Migraines develop when blood vessels inside the head become swollen and inflamed. The swollen tissues send pain signals to the brain through the trigeminal nerve. This nerve can trigger light sensitivity during a migraine that continues long after your migraine goes away.
Here's how.
The trigeminal nerve begins at the back of the neck, travels through the eye sockets, and ends at the brain. Because of this close connection, the pain you feel from a migraine can travel to the eyes from any location in the head, face and neck. If you experience numerous migraines, the eyes' tissues eventually weaken from the strain, including the tissues that filter and regulate light.
Light enters through your eyes' pupils. The pupils decrease and increase in size to control how much light enters your eyes. When your pupils enlarge and stay that way, they allow too much light to pass through them. Seasonal lights can produce a lot of bright light that aggravates your enlarged pupils.
How Can You Enjoy the Season's Lights and Decorations?
Until you see the eye doctor, change how you view seasonal lights. For instance:
Keep the tips above in mind when you visit any location that has bright, seasonal lighting.
If you have a history of migraines or any other head and facial pain, you should tell your ophthalmologist during your appointment. The doctor may refer you to a specialist to evaluate your migraines after treating your light-sensitivity. For more information, visit websites like http://arizonaeyes.net.
