Gas Permeable Contact Lenses

Also known as oxygen permeable contacts, gas permeable contact lenses are a lot easier to take care of then other types of contacts – including soft contact lenses. GP (Gas Permeable) contacts are made from a combination of fluorine and silicone, meaning that they wont attract protein near as much as other types of contacts. If you have had a problem with protein on your lenses in the past, GP contacts will pretty much eliminate that problem.

Keep in mind, youll still need to clean your GP lenses, in order to keep them free of protein, debris, and to keep them comfortable when you wear them. They clean much easier and faster than soft lenses, and they will last you longer as well. For a lot of contact lenses users, gas permeable lenses are the preferred way to go.

If you wear GP lenses or looking to wear them, youll need to keep a re-wetting solution or saline drops with you just in case they start to get dry. Anytime your eyes feel dry, you can use the drops to moisten your eyes back up, and keep your contacts comfortable. Re-wetting drops are normal to use, even with soft lenses. Dryness in the eyes is very common with contacts, which is why you should always have re-wetting drops with you.

After you have worn your GP lenses during the day, you should always clean, rinse, and dry them out once you take them out for the night. When you clean them, you should always use the right solution, instead of water. If you soak them in water it could damage the material, which could in turn damage your eyes. Depending on the type of contacts and brand you have, you should pick the solution accordingly. The solution you use shouldnt burn your eyes, or cause you to feel any type of discomfort.

When you go to your optician to have your eyes fitted for contacts, be sure to ask about gas permeable contacts. If your eye doctor thinks they are right for you, he should recommend them. Normally, they are for older people, or those who have had eye problems in the past. They are strong contacts – and perfect for daily wear.

If youve been looking for contact lenses that wont disappoint, GP lenses are everything you need. They can be purchased locally or online, normally at the same price of soft lenses. They last longer than soft lenses, meaning that you wont need to purchase them quite as often. If you take care of them, they should last you for a long time. Once you have tried gas permeable contact lenses and see just how great they are – youll never look at soft contact lenses the same way again.

What to look out for in Alzheimer’s

Alzheimer’s disease is a slow brain disorder the eats away the brain functions little by little. The disease develops completely between seven to 10 years. As it progresses, the disease affects various brain functions like memory, movement, judgment, abstract reasoning and even one’s behavior.

Because of the long development stage of the disease, Alzheimer’s has been categorized into three levels which described its progression. These are mild, moderate and severe. These categories defined the disease from early (mild) to middle (moderate) until the final (severe) stages of the disease.

During the early stages of the disease, the symptoms are less noticeable and are often times left unchecked and considered trivial by family members and even the patient themselves. Among the early and classic signs Alzheimer’s disease is the gradual loss of short-term memory.

At times, they find to be at lost while performing normal activities. Or they might get disoriented and get lost in places that they have been before. Also, at this stage, people afflicted with the disease may experience lapses of judgment and slight changes in personality. Mood swings and personality changes will start to worsen as the disease progress.

Moreover, attention span is reduced because of the presence of the brain disorder. People with Alzheimer’s tend to be less motivated to complete activities or tasks. Furthermore, they become more stubborn and would oppose changes and new challenges set forth before them.

These are the general conditions or symptoms of people with the disease. The symptoms vary from person to person. Moreover, some other symptoms include speech problems, failure to identify or recognize objects, no recalling how to use simple, ordinary things like a pencil, and not remembering to turn off the lights, stove, or even lock doors and windows. As the disease progresses so do the symptoms.

However, if one acquires or notice the presence of some of the symptoms it does not necessarily mean that one has already been afflicted with the disease. Loss of memory for example might be just a normal cause of aging or other normal factors. Memory loss in Alzheimer’s is more frequent.

People with the disease will more frequently forget words or names during conversations. And because they become conscious of their forgetfulness, they tend to avoid conversations and would rather keep quiet in order to avoid mistakes and embarrassments. They will then become withdrawn which can cause a myriad of other problems like depression and anti-social behaviors.

Other things that might happen are the discovery of things in odd places. One might find books inside freezers, clothes in dishwasher and even plates in washing machines. People with Alzheimer’s will ask questions repeatedly up to the point that it becomes irritating. They can be provoked quite easily and can surprisingly flare up in anger.

Even though no cure has yet been discovered or developed for Alzheimer’s, there are ways that have been created to delay the progression of the disease. Earlier symptoms of the disease respond well to various treatments.

Because the rate of progression differs from person to person, severe dementia occurs within five years to a decade after diagnosis. Because of present treatments and medications, some people diagnosed with Alzheimer’s can live more than 10 years after diagnosis. Some even live up to 20 years after the initial diagnosis was made.

It is a fact that most people with Alzheimer’s don’t die of the disease itself, but of infections and other tertiary diseases like pneumonia, or urinary tract infection or complications resulting from concussions.

Heat-Related Illnesses in Teens

Heat related illnesses are caused due to prolonged exposure to heat and also humidity without any reprieve and due to inadequate intake of fluids. Kids and teens adjust to the variations in heat compared to adults who adapt more quickly. However the heat production is high in them when compared to adults but sweat relatively less. Sweating is the natural action of the body and cooling mechanism to counter heat. Kids and teens often ignore these facts and do not hydrate themselves enough while playing, participating in sports and exercises.

Kids and teens with health problems that are chronic or those who are on certain prescription could be more susceptible to heat related problems. Overweight adolescents or those who wear heavy clothing in times of exertion also suffer heat related illnesses. Heat related illnesses are basically classified into three types. They are: Heat cramps, heat stroke and heat exhaustion.

Heat cramps are the mildest of all heat related injuries and constitute aching muscle cramps and also spasms that occur during intense exercising and also after intense exercising and also sweating in high heat. The symptoms of heat cramps include cramps that are painful in the legs. Flushed and moist skin is also symptoms of heat cramps. The symptoms could also include mild fever generally below 102 degree Fahrenheit. Teens suffering from heat cramps should move to a cool place and take adequate rest. Remove any excessive clothing and wear or put cool clothing on skin or cool skin using air conditioner or fan. Sports drinks which are cool and which contains sugars and salts can also be taken. Stretching out cramped muscles slowly and steadily also helps reduce heat cramps.

On the other hand hear exhaustion is more serious and severe compared to heat cramps and occur due to heavy loss of salt and water from the body. Extreme heat conditions, inadequate fluid intake and excessive sweating results in this conditions. Also, heat exhaustion occurs as a result of inability of the body to maintain the body temperature below the normal which can deteriorate further and also result in a heat stroke which is even worse. The symptoms of heat exhaustion are: muscle cramps, moist skin, pale skin, nausea, fever above 102 degree Fahrenheit, diarrhea, vomiting, fatigue, headache, weakness, anxiety and faint feeling. Teens suffering from heat exhaustion should stay in cool surrounding and take enough rest. Removing excessive clothing, putting on cool clothes and sitting in fan or air conditioning also helps the situation. Intake of cold sports drinks which contains salts and sugars are also advisable. If a teen doesnt show any signs of improvement even after taking all these measures a physician should be consulted immediately.

Heat stroke is the severest condition of all heat related illnesses. In this condition the body gets overwhelmed with excessive heat and the efficiency of the system that regulates body heat goes down considerably which can result in a serious emergency requiring immediate medical care. The symptoms of heat stroke include dry and warm skin, very high fever generally above 104 degree Fahrenheit, increased heart rate, appetite loss, nausea, headache, vomiting, fatigue, agitation, confusion, stupor, seizures, coma and possible death. A teenager experiencing symptoms of heat stroke should stay in a cool place and have adequate rest. Heat stroke is a serious condition and emergency attention should be sought by calling 911. In the meanwhile the affected teenager should be made free of excessive clothing and should be worn with cool clothes and also put cool water on the skin to lower the temperature. Placing ice bags in armpits also helps. Make the teenager drink cool drinks if the teenager is alert.

Heat strokes are very much preventable if certain precautions are taken like drinking adequate water during hot days, avoiding alcoholic and caffeine drinks, wearing light clothes, exercising in cooler time of the day, wearing sunglasses and hat, using umbrella on a hot day, applying sun cream with a spf of at least 15 etc.

How Lasers Work in Laser Hair Removal

Laser hair removal works by the process of selective targeting of a specific area of the body and using a specific wavelength to absorb light into that area. It does not work on a hair by hair basis, instead it focuses a wide beam of light that treats many hairs at one time. The wavelength of light absorbed has to be sufficient enough to damage the targeted tissue area while leaving the surrounding area basically untouched. The principle behind this process is called selective photothermolysis.

Lasers are intense beams of monochromatic and coherent light. These light beams are produced by laser devices that contain either minerals or gases. The four main types of lasers are solid state, semiconductor, gas and dye.

An electric current stimulates the gas or mineral properties which excites the atoms. The atoms then emit narrow, cohesive, parallel light beams which are all the same wavelength. The light beams are focused just for a fraction of a second on the dark hair pigment at the matrix of the dermal papilla, which is the small, cone shaped indentation at the base of the hair follicle that the hair bulb fits into. The light beam is absorbed and heats the pigment which vaporizes the dermal papilla. The more intense the light beam the hotter it makes the pigment. This results in the dermal papilla being severely damaged or destroyed.

Most people believe that laser hair removal works best on hair that is in its anagen phase. This means that the hair is actively growing and is attached to the dermal papilla. The theory behind this belief is that if the dark pigment in the hair shaft extends all the way down to the dermal papilla, it will be destroyed and vaporized by the coherent light beam that is focused upon the area. This happens because the light beam will follow the dark pigment all the way down to the derma papilla.

Visible light has wavelengths that range from 390 to 770 nm, or nanometers. Lasers operating in this range allows for successful laser hair removal without causing any damage to the dermal tissue. Lasers with a light source that operates between 700 to 1000 nm targets melanin in the hair shaft effectively. For example, the wavelength of an alexandrite laser is 755 nm, which is red in the visible range of the electromagnetic spectrum, making its target melanin. The stronger, or greater, the wavelength, the deeper it penetrates target selectively absorbing the wavelength.

Laser hair removal uses several varying wavelengths of laser energy. These wavelengths range from near infrared radiation to visible light. The three most commonly used lasers for hair removal are Alexandrite, Pulsed diode array, and NeoDymium Yttrium Aluminum Garnets, Also know as Nd:YAGs. The wavelengths of these lasers are 755nm, 810nm, and 1064nm respectively.

Laser hair removal utilizes a complex system of science and physics which are precisely balanced to work effectively and safely on the human body. As technology continues to advance in laser hair removal, this process continues to grow in popularity.
