What are Extended Wear Contact Lenses?

Most contact lenses are supposed to be removed during the night. The reason? Contact lenses tend to reduce the oxygen to the cornea, which can result in an infection. If you would like to wear contact lenses continuously (day and night) , you can choose extended wear contact lenses. These contact lenses allow the supply of oxygen to cornea, as a result you can use the lenses continuously (24 hours a day) for a period of 7 days or more.


What are Extended Wear Contact Lenses?

Extended wear contact lenses can be worn continuously (day and night). They can be used for a period of 7 days. Some of them can also be used for 31 days (or 30 nights). 

After this period, these lenses can be disposed and replaced by a new pair of lens.

Extended wear contact lenses are made of silicone hydrogel. This material provides transmission of oxygen through the lens, and then to the cornea.

Problems with earlier contact lenses

In 1981, FDA had approved some contact lenses for continual wear. However, these lenses reduced the oxygen supply to the cornea.

When oxygen supply is reduced, the eye would be unable to fight the microorganisms.

This can increase the risk of eye infection. As a result, eye care specialists advised the patients to remove the lens before sleeping.

In contrast to the old lenses, the newer extended wear contact lenses are made of silicone hydrogel.

This material allows the supply of oxygen to cornea and is safe for continuous wear.

If you are interested in extended wear contact lenses, do consult your eye doctor for the lens which suit you. While some may be suitable for 7 day continual wear, others would be suitable for 31 day continual wear.

Health Checks you can do-it-yourself

 Health Checks you can do-it-yourself

Most people accept, “to pay thy self”. However, with respect to “health” as a priority, very few follow this rule.  Most of the health check-up packages are turned down, mostly saying,
 
This list of health checks are not related to me.
Cost of health check package is too high.
I assume I am healthy, let me have it next time.  & list goes on…..

For whatever may be the reason, if you are not having a health check-up, here are the few check points to know how healthy and fit  you are, as opposed to look like. Remember, these are mostly know to all of us and can be done yourself

Tongue

Among the primary examination your family physician/corporate doctor do is to look your tongue.

But keep looking at your own tongue which can help you spot certain conditions. Contrary to popular belief, “a bald patch on the tongue - a pattern which resembles a map, means you are perfectly healthy”.

However, medics say “white spots on the back of your tongue and inside of your cheek can indicate thrush - a yeast infection that thrives in moist areas of the body”.

If you notice a lump or ulcer on your tongue that fails to heal after a few weeks, this could be the first signs of tongue cancer - a rare form of cancer that affects smokers and people around the world who chew on beetle nut. 

Frequency for check:
Try this and check your tongue once a month.


Eyes


Surprisingly, your eyes can reveal a variety of health conditions.
If you pull down your bottom lid and underneath appears pale - rather than pink - this could mean you are anaemic, a condition which indicates a deficiency in iron. If the whites of your eye have turned yellowish, this could be jaundice - where bile in the liver fails to reach the intestine due to a blockage.

A grey ring around the white of the eye which could point to high cholesterol, particularly in younger people. On the other hand, badly puffy bags under the eye could be a tell tale sign of too many toxins - the result of excessive drinking or smoking. Any scratches or spots on the cornea (the transparent part of the front of your eyeball) could be the first sign of shingles or herpes.

Anyone who suffers from allergies - such as hay fever - may notice transparent bubbles on the inside of their bottom eyelid. Consult your doctor if you notice any of the above symptoms.


Frequency for check
Try this and check your eyes every month.

Skin

If you are over 25 years old and notice more spots than usual on your face, this could mean you are suffering from a hormone imbalance which can lead to Pelvic Inflammatory Disease (PID) or ovarian cysts, claim doctors.

If you look in the mirror and notice a red nose, says Dr Catti Moss, a GP in Northamptonshire, the chances are it is not linked to drinking too much. It is more likely to be 'acne rosacea' - a type of chronic acne that affects your face. 

Keep an eye on your skin, particularly if you are fair-skinned, sunbathe or have a family history of skin cancer. If you have moles and they suddenly start to grow, have become darker or have started to bleed, consult your doctor to check that it is not skin cancer.

Frequency for check

Examine your skin once every two to three months, particuarly if you are fair-skinned.

Breath


Bad breath is an obvious indicator of gum disease. Ninety eight per cent of us suffer from bad breath - the result of foul-smelling gases called volatile sulphur compounds (VSCs) that lurk in our mouth.
Such smells are given off from dead cells and bacteria feeding off food particles that thrive in the hot, moist environment of our mouth.

The best way to check is to lick your wrist. Start with the back of your tongue and move it forward across your wrist. Leave the saliva to dry for ten seconds on your wrist. Then smell this area for any unpleasant odours.

Bad breath is the result of poor mouth care, a weak immune system, stress, or badly fitted fillings (where food can get lodged between the filling and tooth).

Frequency for check

Check your breath if you suspect it smells and see your dentist every six months for a check-up.
