There is generally no treatment to cure color deficiencies. ″The American Optometric Association reports a contact lens on one eye can increase the ability to differentiate between colors, though nothing can make you truly see the deficient color.″

The fluid accumulation can be drained by aspiration, but this may be only temporary. A more permanent alternative is a surgical procedure, generally, an outpatient ambulatory (same-day) procedure, called a hydrocelectomy. There are two surgical techniques available for hydrocelectomy.

- Hydrocelectomy with Excision of the Hydrocele Sac: Incision of the hydrocele sac after complete mobilization of the hydrocele. Partial resection of the hydrocele sac, leaving a margin of 1–2 cm. Care is taken not to injure testicular vessels, epididymis or ductus deferens. The edge of the hydrocele sac is oversewn for hemostasis (von Bergmann's technique) or the edges are sewn together behind the spermatic cord (Winkelmann's or Jaboulay's technique). Hydrocele surgery with excision of the hydrocele sac is useful for large or thick-walled hydroceles and multilocular hydroceles.

- Hydrocele Surgery with Plication of the Hydrocele Sac: The hydrocele is opened with a small skin incision without further preparation. The hydrocele sac is reduced (plicated) by suture Hydrocele surgery: Lord's technique. The plication technique is suitable for medium-sized and thin-walled hydroceles. The advantage of the plication technique is the minimized dissection with a reduced complication rate.

If the hydrocele is not surgically removed, it may continue to grow. The hydrocele fluid can be aspirated. This procedure can be done in a urologist's office or clinic and is less invasive but, recurrence rates are high. Sclerotherapy, the injection of a solution following aspiration of the hydrocele fluid may increase success rates. In many patients, the procedure of aspiration and sclerotherapy is repeated as the hydrocele recurs.

Most birthmarks are harmless and do not require treatment. Pigmented marks can resolve on their own over time in some cases. Vascular birthmarks may require reduction or removal for cosmetic reasons. Treatments include administering oral or injected steroids, dermatological lasers to reduce size and/or color, or dermatologic surgery.

"Seeing pink elephants" is a euphemism for drunken hallucination caused by alcoholic hallucinosis or delirium tremens. The term dates back to at least the early 20th century, emerging from earlier idioms about snakes and other creatures. An alcoholic character in Jack London's 1913 novel "John Barleycorn" is said to hallucinate "blue mice and pink elephants".

A Q-switched laser has been successfully used to treat the condition.

Optometrists can supply colored spectacle lenses or a single red-tint contact lens to wear on the non-dominant eye, but although this may improve discrimination of some colors, it can make other colors more difficult to distinguish. A 1981 review of various studies to evaluate the effect of the X-chrom contact lens concluded that, while the lens may allow the wearer to achieve a better score on certain color vision tests, it did not correct color vision in the natural environment. A case history using the X-Chrom lens for a rod monochromat is reported and an X-Chrom manual is online.

Lenses that filter certain wavelengths of light can allow people with a cone anomaly, but not dichromacy, to see better separation of colors, especially those with classic "red/green" color blindness. They work by notching out wavelengths that strongly stimulate both red and green cones in a deuter- or protanomalous person, improving the distinction between the two cones' signals. As of 2013, sunglasses that notch out color wavelengths are available commercially.

It is generally treated surgically, with a hymenotomy or other surgery to remove any tissue that blocks the menstrual flow.

Although widely discussed, there had been scant information in medical research literature aside from a brief article by Chalett and Nerenberg in "Pediatrics" 2000, which found little formal data existed regarding the condition, but concluded that "[t]he treatment is sexual release, or perhaps straining to move a very heavy object — in essence doing a Valsalva maneuver."

Ultrasound is useful if the cause is not certain based on the above measures. If the diagnosis of torsion is certain, imaging should not delay definitive management such as physical maneuvers and surgery.

Treatment may be requested for cosmetic reasons. Traditional techniques such as surgical excision are effective but will leave a scar. Laser therapy has become the mainstay of therapy.

Published research suggests that the Long Pulsed Nd:YAG laser is a very effective, with a clearance rate of 94% following a single treatment. In this study no scarring or other complications were reported.

There are some common witnesses of evil eye are eyes with different colors especially green or blue its common but can be considered as a curse or Badluck but most of the cases are its just the brain. The brain is very complicated and sometimes it gives information from eyes or process from the brain by the memory that are not actually at present. However it can be a curse or a message from the "Devil".

Caffeine is the most widely used alerting drug in the world and has been shown to improve alertness in simulated night work. Caffeine and naps before a night shift reduces sleepiness during the shift. Modafinil and armodafinil are non-amphetamine alerting drugs originally developed for the treatment of narcolepsy that have been approved by the FDA (the US Food and Drug Administration) for excessive sleepiness associated with SWSD.

Blue balls is a slang term for the condition of temporary fluid congestion (vasocongestion) in the testicles accompanied by testicular pain, caused by prolonged sexual arousal in the human male without ejaculation. The term is thought to have originated in the United States, first appearing in 1916. Some urologists call this condition "epididymal hypertension". The condition is not experienced by all males.

In all cases of the disease, thorough study of the distribution and intensity should be determined to help choose a management practice that’s cost effective. For example, if the disease is widespread in a pre-commercial stand, destroying the plantation may be the most effective measure. The area can then be replanted with immune or low-susceptible species. Aerial surveying is a viable tool available for use in areas where there are severely damaged systems. Other management tools include:

- Using up to date models to help predict the spread of the disease can help with management choice

- Susceptible species should not be planted within 100 feet of a disease center

- Remove as many infected roots and stumps as possible to avoid inoculation of healthy plants

- Cut all infected trees within the disease center and all uninfected trees within 50 ft of the disease center

- Stumping is an expensive, yet effective measure in gently sloping, high-quality sites with light soils. After an excavator removes the stump, pieces of the root are torn and fragmented so invading soil organisms deter long-term inocula.

- Push-falling is an alternative to post-harvest stumping. Whole trees are pushed over with machinery to expose diseased roots for removal. Push-falling is effective in areas with slopes less than 30 percent and soil textures that are sandy to sandy loam.

- Applications of chemical fumigation (such as chloropicrin) have been unsuccessful in dealing with Laminated root rot.

The most widely used potassium fertilizer is potassium chloride (muriate of potash). Other inorganic potassium fertilizers include potassium nitrate, potassium sulfate, and monopotassium phosphate. Potassium-rich treatments suitable for organic farming include feeding with home-made comfrey liquid, adding seaweed meal, composted bracken, and compost rich in decayed banana peels. Wood ash also has high potassium content. Adequate moisture is necessary for effective potassium uptake; low soil water reduces K uptake by plant roots. Liming acidic soils can increase potassium retention in some soils by reducing leaching; practices that increase soil organic matter can also increase potassium retention.

Melatonin is a hormone secreted by the pineal gland in darkness, normally at night. Its production is suppressed by light exposure, principally blue light around 460 to 480 nm. Light restriction, or dark therapy, in the hours before bedtime allows its production. Dark therapy does not require total darkness. Amber or orange colored goggles eliminate blue light to the eyes while allowing vision.

Melatonin is also available as an oral supplement. In the US and Canada, the hormone melatonin is not classified as a drug; it is sold as a dietary supplement. In other countries it requires a prescription or is unavailable. Although it is not licensed by the FDA as a treatment for any disorder, there have been no serious side effects or complications reported to date.

Melatonin has been shown to accelerate the adaptation of the circadian system to a nighttime work schedule. Melatonin may benefit daytime sleep in night workers by an additional direct sleep promoting mechanism. Melatonin treatment may increase sleep length during both daytime and nighttime sleep in night shift workers.

Treatment for horses with thrush includes twice-daily picking of the feet, taking special care to clean out the two collateral grooves and the central sulcus. The feet may then be scrubbed clean using a detergent and/or disinfectant and warm water, before the frog is coated with a commercial thrush-treatment product, or with iodine solution, which may be soaked into cotton balls and packed into the clefts. Several home remedies are used, such as a hoof packing of a combination of sugar and betadine, powdered aspirin, borax, or diluted bleach. It is best, however, to speak with the horse's veterinarian, to be sure these home remedies are effective and, more importantly, safe for use on horses.

Horses with thrush, or those at risk for contracting it, are best kept in a dry, clean environment. Daily cleaning of the hooves also contributes to the prevention of thrush. In general, thrush is relatively easy to treat, although it can easily return and it can take up to a year for a fully healthy frog to regrow after a severe infection.

The evil eye is a curse believed to be cast by a malevolent glare, usually given to a person when they are unaware. Many cultures believe that receiving the evil eye will cause misfortune or injury. Talismans created to protect against the evil eye are also frequently called "evil eyes".

The idea expressed by the term causes many different cultures to pursue protective measures against it. The concept and its significance vary widely among different cultures, primarily in West Asia. The idea appears several times in rabbinic literature. It was a widely extended belief among many Mediterranean and Asian tribes and cultures. Charms and decorations with eye-like symbols known as nazars, which are used to repel the evil eye, are a common sight across Armenia, Albania, Tunisia, Turkey, Egypt, Iran, Iraq, Pakistan, Israel, Morocco, Greece, the Levant, Afghanistan, Syria, southern Spain, and Mexico, and have become a popular choice of souvenir with tourists.

Children with blue diaper syndrome are put on restricted diets. This is in effort to reduce kidney damage. Restrictions include: calcium, protein, vitamin D, and tryptophan. Calcium is restricted to help prevent kidney damage. Examples of food with high levels of tryptophan include turkey and warm milk.

Antibiotics may be used to control or eliminate particular intestinal bacteria. Nicotinic acid may be used to control intestinal infections.

Genetic counseling can also be beneficial, as well as taking part in clinical trials.

Dry eye is a major symptom that is targeted in the therapy of CVS. The use of over-the-counter artificial-tear solutions can reduce the effects of dry eye in CVS.

Asthenopic symptoms in the eye are responsible for much of the severity in CVS. Proper rest to the eye and its muscles is recommended to relieve the associated eye strain. Various catch-phrases have been used to spread awareness about giving rest to the eyes while working on computers. A routinely recommended approach is to consciously blink the eyes every now and then (this helps replenish the tear film) and to look out the window to a distant object or to the sky—doing so provides rest to the ciliary muscles. One of the catch phrases is the "20 20 20 rule": every 20 mins, focus the eyes on an object 20 feet (6 meters) away for 20 seconds. This basically gives a convenient distance and timeframe for a person to follow the advice from the optometrist and ophthalmologist. Otherwise, the patient is advised to close his/her eyes (which has a similar effect) for 20 seconds, at least every half-hour.

Decreased focusing capability is mitigated by wearing a small plus-powered (+1.00 to +1.50) over-the-counter pair of eyeglasses. Wearing these eyeglasses helps such patients regain their ability to focus on near objects. People who are engaged in other occupations—such as tailors engaged in embroidery—can experience similar symptoms and can be helped by these glasses.

A Pacific University research study of 36 participants found significant differences in irritation or burning of the eyes, tearing, or watery eyes, dry eyes, and tired eyes, that were each improved by filtering lenses versus placebo lenses, but in a follow-up study in 2008, the same team was not able to reproduce the results of the first study.

Competing research has shown blue light-filtering lenses decrease specific aspects of light emissions. Theoretical reductions in phototoxicity were 10.6% to 23.6%. Additionally, melatonin suppression was reduced by 5.8% to 15.0% and scotpic sensitivity by 2.4% to 9.6%. Over 70% of the participants in this testing were unable to detect these changes. The expansion of technology has led to more individuals utilizing computers and televisions which increase the overall exposure to blue light. This has opened up opportunities for companies such as Gunnar Optiks and Razer Inc. to create glasses focused on reducing the exposure to blue light.

There is currently no treatment or cure for Waardenburg syndrome. The symptom most likely to be of practical importance is deafness, and this is treated as any other irreversible deafness would be. In marked cases there may be cosmetic issues. Other abnormalities (neurological, structural, Hirschsprung disease) associated with the syndrome are treated symptomatically.

Outpatient treatments such as interventional radiology, lasers, and physical therapy are employed to reduce the severity of the vascular lesions. However, in some cases lasers have caused a reaction in the tissue causing it to expand and become exposed to infection. Excision and grafting may be necessary to remove the lesion. Recovery time on such an operation ranges from 3 to 12 weeks depending on location of the graft, healing time and the possibility of complications.

There is no specific treatment for Chédiak–Higashi syndrome. Bone marrow transplants appear to have been successful in several patients. Infections are treated with antibiotics and abscesses are surgically drained when appropriate. Antiviral drugs such as acyclovir have been tried during the

terminal phase of the disease. Cyclophosphamide and prednisone have been tried. Vitamin C therapy has improved immune function and clotting in some patients.

There are five known levels of CEV perception which can be achieved either through chemical stimuli or through meditative relaxation techniques. Level 1 and 2 are very common and often happen every day. It is still normal to experience level 3, and even level 4, but only a small percentage of the population does this without psychedelic drugs, meditation or extensive visualization training.

Dichromacy ("di" meaning "two" and "chroma" meaning "color") is the state of having two types of functioning color receptors, called cone cells, in the eyes. Organisms with dichromacy are called dichromats. Dichromats can match any color they see with a mixture of no more than two pure spectral lights. By comparison, trichromats require three pure spectral lights to match all colors that they can perceive, and tetrachromats require four.

Dichromacy in humans is a color vision defect in which one of the three basic color mechanisms is absent or not functioning. It is hereditary and sex-linked, predominantly affecting males. Dichromacy occurs when one of the cone pigments is missing and color is reduced to two dimensions.
