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.

7 Easy ways to get relief from computer eye strain

Do you spend long hours in front of the computer? If you do, you may be experiencing eye strain on a regular basis. Eye strain is a common problem and is characterised by fatigue, decreased productivity, red eyes and eye twitching. You can get rid of eye strain by making use of any one of these simple tips. 

1. Ensure that your workplace has correct lighting
Often eye strain occurs as a result of improper lighting. This can be caused by exposure to bright sunlight coming in from the windows and doors or excessively dazzling indoor lights. You can avoid extra lights by keeping blinds or shades closed and by avoiding high-intensity bulbs or fluorescent lights. Alternatively, opting for incandescent or halogen lighting can be beneficial.

2. Minimise glare
You can install an anti-glare screen on the monitor of your computer to minimise glare. Keep the windows covered to reduce glare caused by outdoor sources.

3. Modify the display settings of your computer
You can modify the display settings of your computer in the following manner to reduce eye strain:
• Brightness-Set the brightness of the display to a level, which equals the brightness of your workplace.
• Text size and contrast-Modify the text size and contrast according to the comfort level of your eyes. For most people, black text colour on a white background ensures minimum eye strain and maximum convenience.
• Colour temperature- The spectrum of visible light, which a colour display usually emits is its colour temperature. Blue light is considered to cause more eye strain. So, you should decrease the colour temperature to minimize the amount of blue light emitted by your computer’s display.

4. Try some eye exercises
You can practise some easy eye exercises to prevent your eyes from getting tired. Try staring at a distant object for 10-15 seconds and then looking at any nearby object for another 10-15 seconds. Return your gaze to the first object. Repeat 10 times.

5. Opt for some computer eyewear while working
Try wearing a pair of computer glasses while working. They ensure that your eyes remain correctly focussed on the computer screen, while reducing strain to a minimum. Computer glasses also prove to be very effective in diminishing glare. 

6. Take short breaks at regular intervals
Apply the 20-20 rule to your work regime. After each 20 minutes of work on the computer, give your eyes a 20 second break by looking away from the screen towards any object located 20 feet away from you.

7. Go for a comprehensive eye exam
Make sure that you go for a comprehensive eye exam every year to reduce vision problems caused by computers. This will also help in detecting the root cause behind your problem, so that you can effectively employ curative or preventive measures to control eye strain.

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.

Warts - How To Get Rid Of Them?

Everyone wants to have a bright and radiating skin. But blemishes and skin abnormalities are common and can occur due to lifestyle, diet or hormonal imbalances. Moles and warts are typical skin issues. But how do you tell them apart?

Moles   What are they?

Hardly ever causing pain, they appear in many different colours and can be bumpy or flat. Most often of red, brown or black colour, they occur as a result of skin pigmentation called melanocytes. They can be caused due to direct exposure to sunlight or due to genetic factors as well. They can appear in any part of the body and form slowly, taking a long time to grow.

Warts   What are they?

Small bumps or rough growth on the skin that appear in hands, legs, fingers, soles of the feet, face or in the genital area manifest as warts. They are white or pale. They occur as a result of harmful virus infection of Human Papilloma Virus (HPV) and hence, can be contagious. As opposed to moles, warts need to be removed quickly since a virus causes them.

How do you differentiate a mole from a wart?
Below are some common characteristics of each that can help you identify the skin problem:

Moles

Either flat or elevated from the skin, they are commonly referred to as beauty marks or birth marks.
At times, they have hair growing from them.
Usually, they have one colour   mostly on the darker side.
It cannot be transmitted between people.
They are generated by a collection of pigment cells in the body and darken during hormonal changes.
They tend to become cancerous and lead to melanoma.
Warts

They are harmless, yet contagious.
They have small black or dark dots in the centre that are tiny blood vessels, which provide them with nutrients.
They grow outwards on the skin with a scaly or bumpy deposit.
They can grow anywhere on the body, but are commonly found in feet, hands or fingers.
How to treat warts and moles?

The good news is that both warts and moles do not pose a grave risk to your health, but they are annoying and can turn dangerous in the long run. Especially with warts, you can give it to someone or acquire from someone, since it is a type of virus infection. So, seek medical assistance if you want them to be removed from your skin.

Be aware of the difference between warts and moles to know what you are dealing with. Consult a dermatologist to decide the right steps to remove it or not.

Warts vs. Moles - All You Need To Know!

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.

UV Rays - Are They Damaging Your Eyes?

The ability to see is one of our greatest powers and it needs to be valued and looked after. Sometimes this involves wearing glasses to improve our vision. Spectacles not only help us see better but also prevent straining and further deterioration of the eye muscles. Here are a few signs to watch out for that will indicate your need for spectacles. Keep in mind however that a comprehensive eye exam is the only way to determine the power required for your spectacles. 

-  Blurred vision
Blurred vision or the inability to focus on something in the distance is one of the first signs or eye deterioration. When it comes to children, watch out for complaints of inability to read the writing on class blackboards.

-  Frequent headaches
Unexplained headaches that come and go could be a sign that you need glasses. These headaches can usually be felt at the end of a long day or after watching television. 

-  Constant squinting
Squinting is a natural way to improve vision. This is because the act of squinting reduces extra light and light scattering thus allowing us to see something clearer. Thus, if you notice yourself squinting more than usual it is time to schedule an eye exam.

-  Difficulty working on a computer
Struggling to read figures and words on a computer screen is usually a sign of poor vision. Try adjusting your screen angle and the distance of the screen from your eyes to see if your vision improves or worsens. 


-  Difficulty adjusting to lights
Sudden increased sensitivity to lights can be a sign of many eye disorders with vision problems being the most common. 


-  Eye strain
Occasional pain in the eyes after a long day or as a result of an allergic reaction is nothing to worry about. However, if this pain persists for a few days, it could be an indication that you need spectacles. 
Deterioration of vision is usually a very gradual process and so you may not realize when it begins. However, the earlier you start wearing corrective glasses to improve your vision the easier it will be to control the deterioration of the eye muscles and you may even be able to rectify your condition completely. So, do not ignore any of these warning signs. Even if you do not have any of these symptoms, it is a good idea to get a thorough eye examination at least once a year.
