Relief for Dry Eyes: BioTears First

    
BioTears First - the healthy tear film standard of care.
BioTears is a patented next-generation dietary supplement from the inventors of HydroEye. It is designed to systemically address the root inflammatory cause and effects of dry eye syndrome. It's suggested in peer-reviewed literature that these specific nutrients support normal production of lubricants in other affected parts of the body, such as mucous membranes of the mouth and vagina, and interior body surfaces such as joints and synovial membranes. BioTears addresses the structure and function of the tear film, which is vital for visual clarity.
BioTears Oral GelCaps contain the optimal blend of Omega 3 and Omega 6 essentials fatty acids, plus all the nutrient co-factors suggested to enhance the metabolic conversion associated with the tear-specific series one anti-inflammatory prostaglandin, PGE1.

BioTears Oral GelCaps include nutrients that are suggested to appropriately inhibit the essential fatty acid arachidonic acid production of the COX2 enzyme, the pro-inflammatory prostaglandin PGE2, and Interleukin Il-6.

BioTears Oral GelCaps include nutrients that are suggested to modulate goblet cell/mucin production in both the stimulated and unstimulated tear, the lacrimal gland aqueous output, as well as the meibomian gland oil output, which is vital to the prevention of evaporative dry eyes.

BioTears Oral GelCaps also contain APO-Lactoferrin, which is suggested to inhibit the growth of both viral and bacterial pathogens in the three-layer tear film.

Condition Overview
Dry eyes, often referred to as Dry Eye Syndrome, is the most frequent patient complaint to eye doctors. Lack of successful treatment is the primary reason patients change eye doctors.

On Living With Dry Eyes: From the English teacher's blog
Who threw the sand in my face?
What streetfight
Was I in last night?
I remember a book
 
I am waiting for the forty-four days of rain.
I am waiting for my trial in the desert to end.
Who gave the nameless their names?
 
 
Pathology of the three-layer tear film:
The Mucus Layer - the closest layer to the corneal epithelium. It is produced by the conjunctival goblet cells, and is absorbed by the corneal surface glycoproteins, creating a hydrophilic surface. Mucin deficiency, or mucopolysaccharide abnormalities, can lead to poor wetting or glycation of the corneal surface with subsequent desiccation and epithelial damage, even in the presence of adequate aqueous tear production.

The Aqueous Layer - the layer between the mucous and lipid layers. It is secreted by the lacrimal gland and incorporates all water-soluble components of the tear film. It also comprises 90% of the tear thickness. The aqueous layer provides moisture and supplies oxygen and important nutrients to the cornea.

The Lipid Layer - the most superficial layer. It is produced by the Meibomiam glands with contributions from the glands of Zeis and Moll of the eye lids. The secretion is an oily material, which is fluid at body temperature and retards evaporation of the aqueous layer and lowers surface tension, thereby allowing the tear-film to adhere to the eye’s surface. Androgen receptors are located in both the lacrimal and meibomian glands. A decrease in circulating androgen hormones can result in loss of the oil laye, exacerbating the evaporative tear loss.

The Blink Reflex renews the tear film by delivering aqueous and lipid to the tear film and sweeping away debris. The normal blink interval is about 5 seconds under normal conditions. The tear film is typically stable for about 10 seconds. Tears are normally evaporated or forced out through the nasolacrimal ducts in the inner corner of the eyes on blinking.

The Root Causes of Dry Eye Syndrome:
Many different things cause dry eye syndrome. The normal aging of tear glands, as well as extended use of contact lens, environmental pollutants, prescription drugs, refractive surgery, auto immune diseases, nutrient deficiencies and other disorders can cause disruption in the tear production and retention process.

Symptoms:
The typical symptoms of the dry eye syndrome include dryness, grittiness, irritation, difficulty reading for long periods of time, burning and even the apparent contradiction of excessive tearing or watering. In extreme cases of dry eye, patients may become unusually sensitive to light, experience severe eye pain, and start to notice diminished vision. Successful treatment may be needed to avoid permanent damage.

Blepharitis can often cause dry eye symptoms due to inflammation of the eyelid margins, which is caused by a bacterial infection (Staphylococci). This condition can compromise the quality of the tear film causing tears to evaporate more quickly. The bacteria produce waste material that can cause a mild toxic reaction leading to chronic red, irritated eyes.

Extended Contact Lens Wear can result in dry eye from corneal oxygen and nutrient deficiency. Protein build-up on contact lens can produce a breeding ground for bacterial growth and surface roughness, further contributing to inflammatory changes. Some contact lens solutions contain preservatives that can also cause chemical irritation of the corneal surface and result in dry eye symptoms.

LASIK Surgery temporarily disrupts the ocular surface/lacrimal gland unit. Also, during LASIK, roughly 60-70% of the superficial nerve fibers in the cornea are severed, which reduces sensation and affects aqueous tear production and delays wound healing. With compromised sensation, the blink rate can slow to the point that the tear film breaks up before the next blink can reconstitute. Though this condition usually clears up after a few months, it may result in mild to severe dry eye syndrome for several months after surgery.

Diseases that may be associated with dry eyes include Rheumatoid Arthritis, Sjogrens Syndrome, Diabetes, Asthma, Thyroid disease, Lupus, and possibly Glaucoma.

Age - Dry eye syndrome affects 75% of people over age 65. Tear volume decreases from age 18 as much as 60% by age 65.

Hormonal changes cause decreased tear production brought on by pregnancy, lactation, menstruation, and menopause.

Medications that can cause dry eyes are antibiotics, blood pressure medications, antidepressants, diuretics, over-the-counter vasoconstrictors such as Visine, antihistamines, birth control pills, appetite suppressants, and ulcer medications.

Computer Use causes most people to blink less frequently (about 7 times per minute vs. a normal rate of around 22 times/minute). This leads to increased evaporation along with the fatigue and eye-strain associated with staring at a computer monitor. Any task requiring a great deal of concentration can result in decreased blink rate.

The conventional treatment for dry eyes is to treat the symptoms not the cause:

Artificial Tears: Some form of over-the-counter artificial tears is usually recommended. Although they may provide temporary relief, they merely palliate the symptoms. Worse, the preservatives can aggravate the condition, and can even kill corneal cells. Tears that promise “get the red out”

Punctal Occlusion: Punctal occlusion is a procedure used to help dry eye patients by closing the tear drainage canals with silicone plugs, which keep most of the fluid from leaving the surface of the eye. This may provide long-term relief.
