Remember how the first sight of something new or attractive made you glow with wonder. Do you remember the first time you saw something spectacular like a huge waterfall...or a bright rainbow after the rain? Our eyes are the gateways to beauty and splendor.
But the gift of sight is not enjoyed y everyone. Even people who are not clinically blind yet have certain impairments can lose a lot of the visual information that can be found around us. Some people with visual impairments get blurred vision, and much worse, visual migraine. A certain condition that deals with altered vision is called visual migraine. There is temporary visual disturbance caused by a vascular spasm in the brain, usually accompanied by headache. This so-called vascular spasm occurs when there is a decrease of blood flow to the ?occipital cortex?, or the part of the brain related to vision.
Symptoms of visual migraine may include seeing a ?shimmering light?, distorted or blurred vision, pulsating and flashing lights, among others. The headache experienced with this kind of migraine can be very painful and debilitating. Nausea and vomiting are also experienced during a visual migraine attack. A typical episode of visual migraine lasts for fifteen to twenty minutes, then fades away. Fatigue is the common after effect of this kind of migraine.
Symptoms of headaches related to the eyes are as follows: burning eyes, fatigue, migraine, sensitivity to light (photophobia) and sound (phonophobia), nausea and vomiting, visual aura (certain visuals when a person is under visual migraine), throbbing pain, and headaches that begin after extensive use of the eyes, which usually happens after reading, using the computer, or watching television.
Visual migraine is usually caused by stress and prolonged periods of exposure to bright lights. Using the eyes in a stressful manner or in any stressful activity may result in such condition. The use of eyeglasses can sometimes strain the person's eyes and may give headaches. Sometimes, headaches are felt if the person experiences sinus conditions, allergies, tumors, hypertension or hormonal changes, not really related to one's eyesight.
There are three major types of visual disturbances when experiencing visual migraine. Being tired and stressed causes a formation of an irregular polygon of ?nothingness? which is usually experienced following the headaches. The size of the circle of ?nothingness? grows as time passes (for about half an hour), then disappears. Another type would also be associated to visual processing. This time, colors are seen but with irregular waves and distorted images. The last type is quite different. It occurs with patterns that are triggered by relaxation, and can quickly lead to a sense of unreality by somewhat getting a 3-D image from what the person already sees.
If visual migraines are to be discussed further, it is factual to know another type of disorder related to visual migraine. Although rare, retinal migraine is also associated to the vascular spasm in which results in full loss of vision. This rare form of migraine causes total blindness in any of the eyes, and usually lasts less than an hour, also with recurring headaches. The headache may occur before or after this attack of retinal migraine. Having visual migraine or even retinal migraine can be disturbing for most people. Proper treatment of these said disorders may help in dealing with such apparitions, or even visual loss (retinal migraine).
1. First, you need to do a research. Check out the seller's track record before buying anything. Read the comments done by previous customers that shares their experience to that seller. Negative information is a warning sign, but a clean complaint record doesn't guarantee that your transaction will go smoothly.
2. Make a note. You need to get the name and contact information of the seller. Keep all your email correspondence for reference. You may wonder why, it is because it is helpful to check with the seller if there is any problem with the item. Remember not to do business with someone who do not want to give these information. A reputable seller or company will be pleased to provide you with lots of references.
3.Be cautious about collectibles and other expensive items. If you cannot physically examine the merchandise before purchasing it, ask for as much photos as you can. Save the photos and documents of the item because this can be a big help for you.
4.Before you pay for the item, ask about delivery, returns, warranties and other services. Get a definite delivery time and be sure that the shipment is insured. If you're buying appliances, find out if there is a warranty and how to get service.
5.Look for information on the auction site about insurance, some auction sites provide insurance that cover buyers up to a certain amount if something goes wrong. Others may have links to third-party programs that offer insurance for a fee. Read the terms of the insurance carefully, there is often a deductible, and there be other limitations or requirements that apply.
6.If you are now ready to do online shopping, remember not to give your personal information to a site. Read first the policy then if you don't like it you can shop somewhere else.
7. Be careful on using your credit card. Remember to use a credit card not a debit card. Unlike debit card, a credit card has a protection when it comes to limiting your liability for fraudulent use.
8. Carefully review your credit card and bank statement each month for unauthorized charges and notify your credit card company or bank immediately if you notice any charges you didn't authorize. Because some sites do these, since they got your credit card number it is easy for them to charge your card without your permission.
9. Keep a copy of your transaction. Print and save a copy of your online transaction including the product description, price and online receipt. Also keep the copies of emails you exchange with the seller.
10. Clean your computer before you leave. Make sure that you delete all personal information. Deleting files using mouse or keyboard commands are not enough, the files are still on the computer's hard drive, and it is easy to retrieved and a lot of scammers knows that. You can use a "wipe" utility program to overwrite the entire hard drive, it makes a files unrecoverable.
