The flying side kick is an advanced technique that is often used for demonstration purposes. If they are done correctly in a fight, they can also be very effective.  This is a longer range technique than a regular side kick. The run-up to the kick provides a lot of momentum, making this a very powerful kick. A common fighting position is to stand with your left foot in front and right foot in back with your body turned almost all the way to the side. Your right fist will be by your chin with your left 12-16 inches (30-40 cm) from your left shoulder. If you are kicking a target then you can take one or two steps only but if you are trying to jump over a target then you may need to get a running start for more speed and power. Plant your non-kicking foot (the front foot) solidly on the ground and push off of it to get into the air. As you push off turn your body to the side to swing your kicking foot into the front. You should also bring your non-kicking foot up so that your opponent cannot sweep it away from you. While swinging your kicking foot into place be sure to bend your knee up the same as you would do for a normal side kick. This bend of your knee creates a lot of extra power when it is straightened, so keeping your leg straight will lead to a much weaker kick.  The farther you bring your knee to your chest, the stronger your kick will be. Keep your heel pointing towards your target. Straighten at the very end of the strike. Timing is very important here so you must practice often to learn how to time your kick properly. A lot of your power comes from straightening your knee at the correct time. Be sure you are the right distance from your target to straighten fully but not so far that the kick barely touches the target. The blade of your foot and heel are the strongest parts of your foot. Your heel is especially strong so if you are going for a knock-out kick then you should strike with the heel for maximum power. Striking with the blade (or outside edge) of the foot is also effective and helps your ankle to absorb the impact of the kick. Bring your knee back to your chest and land. You may find it helps to keep turning in the direction of your rotation and go a full circle to get back into the proper fighting stance.  Thus if you are kicking with your right foot, then after the strike you can keep turning counterclockwise to complete a full circle and face the target once more. Make sure you land on your feet and stay balanced.

Experts recommend that all adults at least get a comprehensive dilated eye exam by the age of 40, and follow up with regular visits thereafter.  Check to see if you have vision insurance or a health policy that covers eye care. Regular health insurance typically covers screenings for those with an increased risk factor for eye disease. If you don’t have insurance coverage, find out the eye doctor’s fee for a routine exam, and for any special testing that may be required. See the right kind of eye care professional at the right time. Ophthalmologists, optometrists, and opticians all deal with eye care and treatment but have different training and expertise.. You can request a referral for an ophthalmologist or optometrist from your family physician, or call a local hospital or medical center’s department of ophthalmology or optometry for information. Most commonly, eye drops are placed in the eye in order to dilate the pupil. The patient’s eyes are then evaluated for vision acuity, coordination of eye muscles, peripheral vision, response to light, color testing, eyelid health and function, the health of the interior and back of the eye, and pressure. Beginning at the age of six months, infants should have their first eye examination. Vision and eye development problems in children are best treated if they are caught early. Some conditions like diabetes, high blood pressure, HIV or AIDS, or thyroid diseases can cause or worsen eye conditions. Additionally, you should also contact your physician right away if you have pain in the eye, unusual red eye, or any of the following issues:  Bulging or misalignment of one or both eyes Dark curtain or veil that blocks your vision Distorted, doubled, or decreased vision, even if temporary Excess tearing Halos (colored circles around lights) Loss of peripheral (side) vision New floaters (black "strings" or specks in the vision) and/or flashes of light Common eye problems and diseases include glaucoma, cataracts, conjunctivitis, retinal disorders, and macular degeneration. These diseases do not always have symptoms, so if you have a sudden change in vision, it is important to contact your health care professional right away.  Cataracts — A cataract is a clouding of the lens in the eye, and are common in older people. By age 80, more than half of all Americans either suffer from cataracts or have had cataract surgery. Common symptoms include blurry vision and seeing halos.  Glaucoma — Glaucoma is a leading cause of blindness in the United States, with the main feature being damage to the optic nerve. Symptoms include slowly losing peripheral vision. There is no cure, but symptoms can be controlled through medication and surgery to lower the eye pressure.  Macular degeneration — More common even than glaucoma, macular degeneration is the leading cause of vision loss, affecting more than 10 million Americans. It consists of the deterioration of the eye’s macula, which is the light-sensitive tissue lining the back of the eye that controls a person’s central vision. Your physician will want to know if you have experienced certain conditions or problems before, or have had family members experience them. Diagnoses of nearsightedness and farsightedness have a genetic component. Additionally, diseases like glaucoma and macular degeneration may also involve genetic causes. Flushing the eyes with saline can help if you accidentally splash cleaning products or other substances in your eyes.
