Visual migraines
There are three visual disturbances that occur in visual migraines, and each of these disturbances is triggered by separate stimuli. This kind of migraine is triggered by tiredness and stress, and this is often followed by your normal migraine headache, accompanied with vomiting. Good to know is that the visuals come after the headaches. If it was the other way around, you would probably experience the vomiting and the visuals at the same time. There is a central irregular point in the eye that becomes nothingness at the start of the migraine, and this might grow and last for around 30 minutes. This is easy for one to get around because you will still be able to see things around the edges of that nothingness. The border of this nothingness has unpredictable sides. It takes time before the nothingness fades and you are able to see properly. A great way of representing this visual migraine is in an oil painting. Superimpose an irregular polygon of a cold color onto the center of the painting. Now portray that polygon to grow in size and it will make an uninteresting painting. Second type, this time the expanding polygon has a major difference. The borders of it appear as bands of pulsating and scintillating color. The colors flow through and around the bands in waves, but irregular ones. There is no central part in the vision that is nothingness, but there is a distorted and broken image of the things you are looking at. If you are one that stares too long at table information on a monitor, visual migraines are usually triggered. If you can get around looking at spreadsheets on a computer, do so. Once you are infected, the migraine usually lasts for an hour. It is better to describe this type of migraine in a water painting. The visual content is high in degree that when trying to express it in a painting it’s difficult. The straight lines in the bands can be portrayed as bright colors scattered with white. Third type, this visual migraine is different. Spreadsheets on a computer can trigger this, but for other reasons. This migraine creates odd space in one’s vision that is not there. This is disturbing and can lead to unbalance. In a portrait, it is better to describe this as a 3D portrait, which can be extremely hard to produce when looking a flat image.

Hawaii activity cruises dolphin snorkeling
An activity with a combination of entertainment and recreation is dolphin snorkeling at the beaches of Hawaii. Interacting with the dolphins is a highlight of most of the Hawaiian vacations. It can be from a boat or swimming alongside in the water. Snorkeling in clear waters, cruising alongside the dolphins, touching them, knowing them is an ultimate fantasy to look for in a Hawaiian activity. The tour operators offering snorkeling have an addition tour of providing snorkeling in combination with the playful dolphins, the colored fishes and sea turtles. The Pawai Bay on the big island of Hawaii is a home for snorkelers opting for the activity of cruising alongside dolphins while snorkeling. The Pacific Bottlenose Dolphin, the Rough-Toothed Dolphin, the Spotted Dolphin and the Spinner Dolphin are the four species of nai’a found in Hawaiian waters. Nai’a is the Hawaiian name for the dolphins. Of these the most popular and frequently spotted species of dolphins are the Bottlenose and Spinner Dolphins. Spinner Dolphins are the smallest. In Kealake’akua Bay on the island of Hawaii, off the Leeward Coast of Oahu, on the southern boundaries of Maui and off the coastline of Lanai are the snorkeler sites not to be missed to snorkel alongside the Spinner Dolphins in Hawaii. The star stealer amongst the cruises, vessels is the Bottlenose Dolphins. With their characteristic playfulness and inshore habits, they are star performers at the oceanariums too. Currently there is an estimate of a few thousand of the Bottlenose Dolphins as inhabitants of the Hawaiian waters. The dolphins come in groups of ten and fifteen to entertain while indulging in the snorkeling activity. At night large herds of the dolphins can be spotted in the deep channels between the islands when they feed, whereas during the day they form smaller groups to rest and play near the shore. Hence the best time to perform the snorkel activity alongside the dolphins in Hawaii would be the daytime. The spectacular leaping high into the air, spinning above water and falling back into the water is one of the treats that these dolphins offer while snorkeling with them. Hawaiian residents and the tourists have been impressive in maintaining nature for the breeding and existence of these dolphins which live a lifetime of about thirty years. The dolphins along the coastline of Hawaiian Islands seem to enjoy the company of the snorkelers. With an ability to learn and imitate behaviors, these dolphins steal the show at the Hawaiian activity of the visitors who come down to snorkel and swim with them.
