Ways to heal yourself without medicine

In the book Unlearning Your Pain, there are listed a few steps that can help you in healing from chronic pain.

First, it is very important to discover what is causing the pain. Most of the people that have chronic pain have pain that is diagnosed as migraine, irritable bowel syndrome or fibromyalgia.  Although this pain is not caused by a process in the body due to a structural disease,  this pain is just as strong as the one caused by fractures, cancer, and infections. This pain is caused by learned neural pathways.  Just as learning to ride a bicycle, you will be developing a learned neural pathway, and you will be able to ride a bike during your life. According to this, pain can be learned, without having a disease process in your body.



Refractive Error: Definition, Causes, and Types

Refractive Errors

What is the SimpLe Definition of refractive error?

The first thing that people should remember is that “refractive error” is just a term or name given to a specific condition already existing in the eyes. So, when trying to understand  what refractive error means, consider that you shouldn’t get stuck with the term “refractive error” when trying to understand the condition.  So, think like the first scientists who discovered this condition to understand it.

When scientists wanted to discover why some people don’t see things as clear as others, they found that every image is created on the eye in this way:  a light rays strike an object and then reflect to the eye to form an  image of that object. These light rays of the object must be focused to form a definite image. So, the eyes have a mechanism for focusing all entering light rays. This focusing mechanism bends the entering parallel light rays and makes them intersect in one plane inside the eye to form a focused image of the object, and this is called “refraction”. For now the image is just focused, and it is not necessarily seen clear by the eye. For the eye to see this image clearly, it must be focused exactly on the retina. If the image is focused some place before or behind the retina, it is seen as non-clear image. The further this image is focused from the retina, the less clearer it seen by the eye.

So,  scientists realized  that the images don’t focus directly in the retina like they should do. This happens when the light rays entering the retina bend more or less than the required degree.

This bending of light rays is called “refraction.” The right refraction in people without eye problems bends light rays and focuses them directly in the retina.

Therefore, any condition in which the  light rays are not focused in the retina is a  “refractive error”.

is “refractive error” a disease?

The tissues of the eye with  “refractive errors” are totally intact. They have no bacteria, no infection, no inflammation and no pathologic imperfection. Thus, there is no disease in the tissues of your eyes since they are medically intact.

The only problem is that light rays don’t focus in the place they are supposed to be focused on – the retina.

correct refractive errorsThere are more than 150 million people worldwide  who are suffering from visual problems due to refractive errors.  However, the good thing is that these eye conditions can be addressed, by prescription eyeglasses or  contact lenses that accurately correct refractive errors.

what ARE THE COMMON causeS of refractive errors?

Refractive errors happen because the eye’s axial length and refraction or  “power of  bending light rays” do not match. Normally, the eye refracts light rays and makes them focus in a distance which is the same as the eye length.

In refractive errors, there are 3 possibilities:

1 – There is no problem with the eye’s axial length but the  light rays are focused in a distance that is not the same as the eye’s axial length.

This can happen in 4 ways which are:

Visual Impairment due to Refractive Errors

a – In myopia, refraction focuses light rays in a distance shorter than the eye length making them focused in front of  the retina.

b – In hypermetropia,  light rays are focuses in a distance longer than the axial length making them focused theoretically behind the retina.

c – In astigmatism, refraction is not equal in all meridians making the image focused in two planes one of them, at least, is in front or behind the retina.

d – In presbyopia, the eye has lost its ability and power of  bending light rays of near objects making them focused in a distance longer than the eye length and thus falling behind the retina.

2 – The eye is able to bend light rays and focus them but it has longer or shorter axial length than normal.

a – In myopia, the eye length is longer than what’s normal.

b – In hypermetropia, the eye’s axial length is too short.

3 – A combination of the above two causes. The eye has different power “refraction” and axial length is either shorter or longer than what’s normal.

There main types of refractive errors are:

1 – Myopia: which is also known as “nearsightedness”. This condition is optically corrected with contact lenses, and there are even single-use, daily contact lenses specifically for nearsightedness.

2 – Hepermetropia: also known as  “hyperopia” and “farsightedness”.

3 – Astigmatism

4 – Presbyopia: an age-related condition common in people 40 and above.

Preventing Irritation After Wearing Contact Lens

When contacts irritate eyelids, most of the time taking them out, cleaning and disinfecting them, and waiting it out for a day or two will cause the eyelid irritation to resolve itself. But sometimes when contacts irritate eyelids, the resulting problems are more serious. There are some different kinds of eyelid irritation. Some of the most common are:

  • Blepharitis
  • Conjunctivitis
  • Corneal irritation
  • Corneal ulcer
  • Episcleritis
  • Subconjunctival hemorrhage

Blepharitis means inflammation of the eyelid margins, where the eyelashes are located. Symptoms of blepharitis include itching, redness, and irritation of the eyelids, and sometimes a “gritty” sensation. Lubricating drops do little or nothing to relieve blepharitis. The two main types of blepharitis are seborrheic blepharitis and staphylococcal blepharitis. Seborrheic blepharitis is the most common and is generally not caused when contacts irritate eyelids. It usually involves not only the eyelids, but the scalp, eyebrows, and ears.

Staphylococcal blepharitis is a staph infection of the edge of the eyelid. The lashes may mat together, and the patient may feel as if there’s a foreign body in the eye. Doctors may prescribe topical antibiotics for this type of blepharitis, but unfortunately, it usually doesn’t help much. In many cases, recovery is a matter of removing contact lenses and waiting for the infection to pass while practicing daily eyelid hygiene with warm wet compresses and careful removal of debris.

Relax your eyes to avoid exposing it to infectionConjunctivitis can easily result when contacts irritate eyelids. Sometimes called “pinkeye,” conjunctivitis leads to redness, irritation, and excessive watering of the eye. An allergy or infection cause it. Common pus-producing bacteria cause bacterial conjunctivitis. Eyes will be crusty and irritated, and there may be pus discharge. There is usually a definite feeling of there being a foreign object in the eye. Often, bacterial conjunctivitis is dormant for three days before showing up in the eye. It is easily spread on towels and washcloths. It usually resolves itself without treatment, though occasionally antibiotics are used.

Chemical eyelid irritation can also trigger conjunctivitis. This occurs when a person is allergic to the cleaning and storage solutions used in cleaning contact lenses. Giant papillary conjunctivitis is “allergic” conjunctivitis caused by repeated physical irritation of the conjunctiva, which can result when contacts irritate eyelids. The patient must avoid wearing contact lenses until the condition resolves.

Corneal irritation is also known as keratitis. It occurs when the cornea of the eye (the transparent membrane over the iris) develops inflammation. It is usually painful and results in temporary visual impairment. When contacts irritate eyelids, corneal irritation can develop. These cases often involve the buildup of Gram-negative bacteria on the contacts.

Contacts can cause corneal abrasionCorneal irritation must often be treated with antibiotics, either topical or oral. In severe cases, intravenous antibiotics must be used. Contact lenses must not be used until corneal irritation has had a chance to resolve completely. Anyone with symptoms of corneal irritation should see a doctor.

Sometimes when contacts irritate eyelids, the result is a corneal ulcer. This is an open sore on the cornea. Eyelid irritation may aggravate tiny rips in the corneal surface and cause an infected ulcer to develop. The rips in the cornea may be caused by a scratch or trauma to the eye. Contact lenses on top of one of these tiny rips may allow bacteria to build up, resulting in an ulcer.

Symptoms of a corneal ulcer include eye pain, irritation, and watering, and in some cases a visible white or grayish spot on the cornea. Vision may be blurry, and there may be the pain when looking at bright lights. Cool compresses, meticulous hand and eye hygiene, and over-the-counter pain relievers like acetaminophen (paracetamol) can help with the pain. A doctor may prescribe antibiotics and prescription pain medication. In severe or unremitting cases, the only treatment may be a surgical corneal transplant.

Episcleritis is an inflammation of the episcleral tissue. This tissue lies between the sclera (the white part of the eye) and the conjunctiva. It can result when contacts irritate eyelids. Usually, episcleritis is mild and goes away on its own within 7 to 10 days. It can be recurrent, however. With simple episcleritis, recurrence usually occurs at one to three-month intervals. Stress, hormonal changes, and allergies may be a factor in recurrent episcleritis. Many, if not most people with episcleritis do not seek medical treatment.

Episcleritis isn’t as painful as corneal irritation or ulcers, but there may be annoying discharge and sensitivity to lights. In some cases, episcleritis may be caused by systemic diseases like rheumatoid arthritis or lupus, so in some cases, contact lens-based eyelid irritation may not be to blame. Treatment generally involves eye and hand hygiene and sometimes wetting drops to help relieve discomfort. Prolonged cases may require the use of corticosteroids or dexamethasone sodium phosphate.

Subconjunctival hemorrhage shows up as a bright red patch on the white of the eye. The area has many fragile blood vessels that can easily be broken or ruptured, and this results in blood leaking into the space between the sclera and the conjunctiva (the membrane over the white of the eye). The condition can result when contacts irritate eyelids. Though it looks painful, it usually is not.

A subconjunctival hemorrhage usually heals itself without treatment, though eyelid irritation, when caused by contact lenses, means that contact lenses should be avoided until the condition clears up. Because the condition is not painful, it is not necessary or recommended for patients to take aspirin or NSAIDs (non-steroidal anti-inflammatory drugs). Artificial tears may be used on the affected eye but should not be used more than absolutely necessary because the artificial tears may slow healing. Contacts irritating eyelids can be a temporary discomfort that resolves overnight, or it can be as dangerous as a corneal ulcer, which requires comprehensive medical treatment. Avoiding eyelid irritation from contacts is simple, though occasionally a person can do everything as he or she is supposed to and still have their contacts irritate eyelids.

Surgeons washing hands thoroughlyAnyone handling contact lenses should first wash their hands thoroughly with plain soap and water and dry them with a lint-free towel. Contact lenses must be cleaned and disinfected as directed by an eye doctor. Daily wear contact lenses that are worn for periods over two weeks may require weekly treatment to remove protein deposits on the lenses. In general, the more often lenses are replaced, the less care and handling they require.

Lenses should be handled only with clean hands, and the tips of the bottles of the solutions must never touch any surface. Contact lens cases must be thoroughly washed out with hot water daily and allowed to dry. Anyone using cosmetic or theatrical contact lenses should never share them with another person. This is a recipe for not only eyelid irritation, but also for a painful eye infection.

Contact lenses are great for vision correction, and they can be fun too, with hundreds of types of theatrical, cosmetic, and special effect lenses available. When handled according to directions and cleaned and stored correctly, contact lenses will probably not cause any problems. But mishandling them, or not cleaning or storing them properly, or continuing to use them after the period in which they should have been discarded can easily make contacts irritate eyelids. Eyelid irritation will usually clear up on its own, but if an infection results, medical treatment may be necessary.
