10 surprising facts about your eyes

You never tend to pay a lot of attention to your eyes unless they are affected by some serious disorder or unless your vision is disrupted. But did you know that your eyes are capable of doing much more than you can imagine? here are 10 surprising facts about your eyes you didn't know about.

1. How intricate!

Your eyes take more than 2 million working parts to function. No wonder your eyes are the second most complex organ of your body after your brain.

2. A lot depends on them

As much as 80% of your memories are determined by what you see. Also, 80% of what you learn is because of your eyes.

3. Retina and security

The iris of your eyes has approximately 256 unique characteristics, which is more than even your fingerprints. This is the reason why retina scans are used so widely today for security purposes.

4. It's a colourful world

Your eyes can distinguish between approximately 10 million different colours. And women with a particular kind of genetic mutation can see millions of more colours.

5. Upside-down

The retina of your eyes receives the vision of the outside world as upside down. It is your brain, which flips the image for you so that you can see the world as it is.

6. Sunscreen for the eyes?

It is possible for your eyes to get sunburnt. Therefore, it is advisable for you to wear sunglasses in order to protect your eyes from the ultraviolet radiations.

People are well aware of the harmful effects that UV rays have on the skin, but very few know that UV rays can damage their eyes as well. The tissue that human eye is made up of is one of the most sensitive tissues in the body and hence, the most vulnerable. The increasing level of UV radiation reaching the Earth s surface every minute has made it indispensable to take the required precautionary measures to protect the eyes.

What are UV rays?

Sunlight consists of 3 types of radiations - Infrared, Visible light and UltraViolet. Artificial sources like lasers, tanning beds and welding machines also emit UV radiation.

There are three types of UV radiations - UV-A, UV-B and UV-C. 

UV-C is absorbed by the ozone layer and does not possess any risk. It is UV-A and UV-B radiations that adversely affect the eyes and vision.

Impact of UV rays on  eyes

Too much exposure to UV rays can affect vision, harm the eyes, and deteriorate overall eye health. There are various eye problems that are aggravated by excessive exposure to UV radiation:

Macular Degeneration: It is caused by damage to the retina over time by UV rays. It leads to age-related blindness. Too much exposure to UV rays increases the risk of developing macular degeneration.
Cataract: It is the clouding of eye s natural lens - the part of the eye that focuses the light we see. Too much exposure to UV rays increases the risk of developing cataracts. 
Pterygium: Often known as  surfer s eye , pterygium is a pink, non-cancerous growth that is formed on the conjunctiva. UV rays are believed to be responsible for the development of this growth.
Skin Cancer of the Eyelids: Too much exposure to UV rays can cause skin cancer in and around the eyelids.
Photokeratitis: Popularly known as corneal sunburn or  snow blindness , photokeratitis is caused due to excessive short-term exposure to UV-B rays. Photokeratitis occurs when you spend long hours at the beach or skiing. It sometimes leads to temporary vision loss. 
How to protect the eyes from harmful UV rays?

Here are some tips to help ensure that eyes are protected against harmful UV rays:

Always use quality sunglasses that block out 99-100 percent of both UV-A and UV-B radiation when outdoors.
Stay away from tanning beds, and if you use them occasionally, always wear eye protection. 
Wrap around frames should be used if you spend a lot of time outdoors.
Be sure to see your doctor at least every two years.

What causes warts? Can we prevent it?

Warts are small formations that occur on the skin. They appear in the form of dark protruding bumps or brown flat lesion on the skin surface. Sometimes they might also have tiny black specks on them. Warts usually form on the hands, feet, face and genitals, although they may appear on other parts of the body in some cases.

What causes the formation of warts?

Common warts are caused due to infection of the outermost layer of skin that occurs as a result of viral contamination. The virus that is responsible for this condition belongs to the human papillomavirus (HPV) family.

This infection is highly contagious and easily spreads from one person to the next. It is most likely to occur on skin that is cut or damaged as that allows easy access for the virus to enter the skin system.

How to prevent the formation of warts?

Common warts are contagious and spread very easily. Preventing the spread of the HPV virus can be done through simple steps that will help you avoid getting affected by this condition.

Some of the preventive measures that can be adopted are as follows:

- picking and scratching on warts should be avoided

- avoid biting fingernails as gnawing on the skin around the nails makes it more prone to infection

- grooming, brushing and shaving around infected areas should be done with care

- moisture and dampness should be avoided as the virus thrives on it

Do not self-medicate with lime (chuna), garlic, onion or Dettol.

Treatment

Wart removal should be done by a qualified dermatologist. It is simple, safe opd procedure which takes few minutes only and does not leave any scars.

What Causes WARTs? Can We Prevent it?

What are Warts?

Warts are infectious outgrowths that may appear on any part of the body. For example, the most common warts occur on fingers. They are caused by virus, most typically the Human Papilloma Virus (HPV) and several of its subtypes. They appear as dense painless rounded nodules of about 0.3- 1 cm in diameter. The mode of transmission of this virus is usually by contact. You can also contract warts by sharing objects like razors, towels or other personal items. They can be sexually transmitted if the warts are present on genitals.

Usually, they are benign outgrowths but sometimes, they may be cancerous if present on genitals.

How To Prevent Warts?

Earlier, the only way to prevent contracting warts was avoiding contact with infected people. But now-a-days, vaccines against HPV are present that are given in teen years to prevent genital warts and cancer caused by them.

How are they diagnosed?

Your doctor can easily tell if the outgrowth is a wart just by having a look at it. If it is not clear, your doctor may take a sample of your skin and look at it under the microscope to ensure that it is a wart.

Treating Warts-

CAUTERIZATION

Cauterization is a medical procedure wherein a part of the body is burnt in order to damage some tissue in order to prevent an outgrowth. Cauterization can be done by medicine, cryotherapy (using localised or general low temperatures to treat benign or malignant tissues), radio frequency cauterization or laser. The method applied depends on size and location of the outgrowth or the choice of you dermatologist as well.

It is recommended to get warts removed at its earliest to prevent spreading of the disease.

Several myths are present in the market that state cure to warts by various homemade remedies but these can do more harm than good. Treating warts must be done by practised medical personnel. Incomplete removal of warts can cause recurrence of warts due to secondary infection.

What crying does to your body

Do you know that every little activity that you perform on a daily basis impacts your body? what you eat, how long you sleep and even every tear you shed affects your body. Most people are aware of how their body reacts to major activities, like exercising, but few are aware of how the body reacts when they cry.

While you are generally concerned with the mental cause and effect of crying, have you thought about what crying does to you physically? tears are not always shed when a person is upset. Tears are a body's way of expressing itself as well as protecting itself. Everything from a happy ending in a movie to a dust particle in the eye can make you tear up.

There are essentially three kinds of tears. Basal tears and reflective tears help keep the eyes lubricated and irritant free respectively. It is the psych tears, which we commonly refer to as crying, that come as emotional responses.

Crying might be a sign of emotional stress and pain but if you are wondering how it harms your body, the answer is that it does not. Crying does not harm one's body physically. In fact it does better than harm to your body, purely physically speaking. Here's how-

- when you cry, your tears help your eyes remain clear.

- it also has anti-bacterial properties that keep your eyes clean.

- your eyes remain properly hydrated thus reducing any kind of irritation. You might feel dehydrated after a while due to the loss of water and salt.

- even the excess manganese in your body gets washed out through tears.

But for some, the act of crying can cause medical complications. It can lead to fits or can cause an acute shortness of breath. For those with severe heart conditions, there can be a cardiac pain. Crying can take a toll on your body if you have certain medical conditions. For most people crying does more good for their body than harm.

Ever noticed spots or strands that  float  into your line of vision. These are known as floaters. In most cases, they do not affect your vision, but can cause a lot of discomfort. Thus, in most cases they do not require treatment unless they affect your vision significantly. Floaters are more likely to stand out when looking at bright objects or something like a clear blue sky. Moving your eyes can shift the fluid in your eyes and move these floaters out of your line of sight.

Dust particles entering and irritating the eye should not be confused with floaters. Floaters can be described as flecks of a protein called collagen. These flecks can be seen when they are loosened from the back of the eye known as the vitreous. This can happen at any age but is more likely to affect people between the ages of 50 and 75. Being near sighted or suffering from cataract also increases your risk of seeing floaters. In rare cases, it can also be triggered by a disease in the eye, an injury to the eye, tumors or crystal deposits in the back of the eye.

Noticing the odd floater is not something to worry about. However, if you notice a sudden increase in the number and frequency of floaters in your eye, see flashes of light, have pain in the eyes or experience a loss of side vision, consult a doctor immediately. This could also be a sign of a more serious condition like a detached retina that requires immediate medical attention. Excessive floaters can be removed through a surgery known as a vitrectomy or laser vitreolysis. A vitrectomy involves the removal of vitreous gel from the middle of the eye and replacing it with silicone oil or a gas bubble. The surgery last 2 or 3 hours, but you may require an overnight stay in the hospital.

Laser vitreolysis is a more recent form of treatment for this condition. This pain free procedure involves the projection of a laser beam into the eye that focuses on large floaters to break them apart or vaporize them. This procedure can be performed as an outpatient and is considered safer than a vitrectomy. The form of treatment suited to a person will depend on a number of factors including their age, what the floaters look like, where they are located and the frequency of their appearance.
