Red-green color blindness
It occurs when red or green cone cells do not function properly, or are completely absent. Have some kind:
Mild green blindness: This is the most common form of color blindness and affects 5% of men, but is rare in women. It occurs when green cone cells do not function as they should. Yellow and green look redder, and it can be difficult to distinguish blue from purple.
Mild red color blindness: It happens when your red cone cells don't work like they should. Orange, red, and yellow look greener, and the colors are less bright. It is usually mild and does not cause problems in daily life. This form of color blindness is very rare in women and affects about 1% of men.
Red color blindness: You don't have working red cone cells. Simple red looks dark gray. Some shades of orange, yellow and green look yellow. It is very rare in women and affects about 1% of men.
Green blindness: occurs when you don't have working green cone cells. Red can be yellow-brown and green can be beige (pale yellow-gray). It affects 1% of men and is rare in women
Blue-yellow color blindness
This type of color blind test ness affects men and women equally. This condition occurs in less than 1 in 10,000 people worldwide.
It happens when your blue cone cells are missing or don't work correctly. This is the second most common type, and it affects men and women equally.
Mild blue-yellow color blindness: occurs when your blue cone cells function in a limited way. Blue looks greener and it's harder to see pink from yellow and red. It is extremely rare.
Blue-yellow color blindness: it occurs when you don't have blue cone cells. Blue looks green, and yellow looks light gray or purple. It is extremely rare
Completely color blind
You don't see any color at all and your vision may not be clear.
There are two types:
Complete cone color blindness: It occurs when 2 of your 3 cone cells: red, green or blue, don't work. When only one type of cone is active, it is difficult to distinguish one color from another. And if one of your defective cones is blue, your vision may not be sharp. You may be nearsighted and may experience uncontrolled eye movements. This is a condition called nystagmus.
Complete rod color blindness: It is the most severe form of color blindness. None of your cone cells have active light-sensitive pigments. As a result, the world appears to you in black, white, and gray. Bright light can hurt your eyes. You may experience uncontrolled eye movements (nystagmus).
Today our eyes are exposed to too many chemicals that cause a number of dangerous diseases such as glaucoma, corneal ulcers, color blind test....
Chemical eye burns are a dangerous and emergency accident, especially in ophthalmology. Chemical eye burns need to be given first aid properly to minimize possible complications to the patient's eyes.
Reason
Acid burns include inorganic acids (sulfuric acid, hydrochloric acid) or organic acids.
Basic burns such as lime burns, alkaline burns.
Accidental eye burns caused by chemicals are acids that often occur in industry, in battery manufacturing, metal plating, laboratories, daily life or when someone intentionally splashes acid in the eyes.
Base burns are common among workers in aluminum manufacturing or soap making facilities. Lime burns are common in the construction industry or in daily life. Eye burns from benzene can occur in rubber manufacturing facilities.
Treatment of eye burns caused by chemicals
The key point in the treatment of chemical eye burns is that the treatment needs to be urgently and accurately to ensure the physiological function of the eye. Depending on the specific case, eye burns will be treated according to different protocols, but the general principles still need to be followed:
Eliminate flammable substances: wash eyes with clean water
Anti-pain
Anti-infection
Non-stick
Enhance corneal nutrition
Treatment of complications and sequelae
Surgical treatment when necessary
Color blindness is a medical term for a person's visual impairment. People with color blindness can see things but cannot distinguish their colors like normal people.
There are patients who only have temporary color blind test, but there are also many cases where they have to accept living with this disease for the rest of their lives.
People with red and green color blindness are often genetic, men account for about 8% and women account for about 0.4%. The cause is determined to be due to the gene for red and green color blindness located on the chromosomes.
People with blue and yellow color blindness make up only about 5% of all people with color blindness.
Effects of color blindness on patients
People with color blindness will have certain effects on work and life even though they can still see everything around them. Difficulties in recognizing colors and distinguishing objects of different colors will affect daily work, especially those related to design, graphics, driving, etc.In addition to people with genetic color blindness, people with temporary color blindness also have it due to trauma that damages the brain, retina, or eye diseases. For those with green and red color blindness who do a driver's job, they may be able to get a driver's license but not a commercial license and not be allowed to drive at night, which can be quite disruptive to the job that the patient will have to accept.
Depending on the extent to which the patient is able to partially perceive colors or not at all. This eye disease does not affect health, but people with color blindness will face many inconveniences in life and work. If you want to know if you are color blind, take the color blind test tool. It good.
What is red and green color blindness in humans?
In the retina of the eye there are two types of rods and cones that perceive light. The cones help detect colors such as red, green, and blue. When these cells are absent, inactive, or detect colors differently than usual, you may have color blindness. Some possible cases are:
Mild green blindness: This is the most common condition, usually seen in 5% of men, rarely seen in women. Then you will see green and yellow look more red, difficult to distinguish blue from purple.
Mild red blindness: Usually affects 1% of men. At this point red, yellow and orange will be greener, deeper colors than usual. At this level, the disease has not had much impact on daily life.
Red blindness: Due to the red cone cells no longer working, this results in seeing red as dark gray. Besides, orange, yellow or green colors will lean more towards yellow shades.
Green blindness: Similar to the red-blind mechanism, the green cones are no longer active. Green can now turn beige, taking on a golden gray hue, while red becomes golden brown.
Hereditary color blindness is an incurable disease, so it is necessary to practice habits to live with this disease. Keep in mind the order of traffic light colors for safe traffic. Note the colors, rearrange the order of colors for easy identification when needed.
If there is any abnormality in vision, it is necessary to see a doctor for timely examination, diagnosis and treatment.
