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?

Glaucoma is a group of eye diseases characterised by damage to optic nerve usually due to excessively high intra ocular pressure (eye pressure). If left untreated can lead to optic nerve damage resulting in progressive, permanent vision loss. Glaucoma usually affects people above the age of 40, but can affect younger people as well. This condition causes fluid to build up in the eye, which puts pressure on the optic nerve. 

There are broadly two types of glaucoma - Open angle glaucoma ( more common in elderly) and angle closure glaucoma.
Women are more likely to suffer from glaucoma than men are. Ethnicity also plays an important role in determining the risk of suffering from this condition. East Asian and African Americans have a high risk of glaucoma, as they have a shallow, anterior chamber depth. Some of the other conditions that can increase a person s risk of glaucoma are:

Diabetes
Hypothyroidism
Myopia
An earlier eye surgery
Retinal detachment
Tumours
Injury to the eye
Long term corticosteroid medication
If diagnosed early enough, glaucoma can be treated and its effects can be reduced. However, the damage already caused by glaucoma cannot be reversed. The aim of glaucoma treatment is to either reduce the production of fluid in the eye or improve its flow. This helps slow down the progression of this disease and prevents any further loss of vision. Glaucoma treatment usually takes the form of eye drops or surgery.

Eye drops are the first step towards treating glaucoma. There are many different types of eye drops. Prostaglandin analogues aim at increasing the flow of fluid out of the eye and are usually prescribed in cases of swelling around the rim of the eyes, darkening of the iris and blurred vision. Beta-blockers can also help lower the secretion of fluids in the eye.

Patients who are also suffering from diabetes or lung conditions such as bronchitis may be prescribed cholinergic agents, carbonic anhydrase inhibitors or sympathomimetic drugs. Cholinergic agents help improve the outward flow of fluid in the eyes while Carbonic anhydrase inhibitors reduce fluid production in the eyes. Sympathomimetic drugs do both reduce the production of fluids and improve outflow.

If the eye drops are not effective, surgery may be advised to lower the pressure built up in the eye. Some of the common types of surgery for glaucoma are:

Trabeculoplasty: This procedure involves directing a high-energy laser beam into the eye to open clogged drainage canals. The surgery has high success rates but the problem may recur after surgery.
Filtering surgery: This involves creating an opening in the eye and removing a part of the trabecular meshwork, thus allowing fluid to flow outwards.
Drainage implants: Children or patients with secondary glaucoma may be treated with this surgery where a small silicone tube is placed in the eye to aid in fluid drainage.

Glaucoma - Factors That Put You Risk!

8 Tips to Keep Your Eyes Cool in Summers

It's the month of Phagun again and time to prepare for the most colourful and vibrant festival of India - Holi. As the festive cheer spreads and people get ready to paint the town red with colours, dance to rocking beats at Holi bashes, and gorge on Gujiya and Thandaai, it s good to remember that you need to play it safely and naturally. The biggest reason for this is the synthetic agents, which are used to make the colours of Holi. What used to be a festival played with flowers, natural dyes and herbs have now transformed into a celebration of colours made from chemicals that are harmful for our body. 

Apart from the allergies to the skin, there is also the risk of increased blood pressure after the Holi festivities due to the high intake of bhaang, the official Holi drink. To avoid the harmful effects of such materials used during the festival, here are some must-follow health tips for you.

Tips to care for your skin

Use organic colours: Skin is the most sensitive body part and synthetic colours are a big no-no for it, as they can lead to rashes and other skin allergies. Therefore, it is advisable that you opt for organic colours, considering they are not only chemical free but are made from natural ingredients. Organic colours are safe for children too, as they are softer on the skin and easy to wash off. It is crucial that you protect kids from synthetic colours as they contain lead oxide, mercury sulphide and aluminium bromide, chemicals which not only damage the skin but can also cause various health issues.
Skin and sun protection: To avoid any kind of damage to the skin from colours, apply a good amount of Vaseline, any other petroleum jelly or mustard oil to your skin. You can also apply this to your child s skin as it is completely safe for their sensitive skin. When playing outdoors, opt for a waterproof sunscreen to protect your skin against sun damage.
Choose the right clothes: Wear long pants and full-sleeved shirts. This will help you stay safe from the harmful effects of colours. 
Tips to care for your hair

Oil your hair: You can apply a generous amount of oil to your hair, this will not only moisturize your hair but also safeguard the scalp and hair from the chemicals in the colours.
Cover your hair: Tie a ponytail and cover your hair with a shower cap to prevent your hair from dreadful damage. For a trendy look, you can also tie a bandana over your hair and safeguard them at the same time. 
Tips to care for your eyes

Wear sunglasses: Synthetic or organic, colours can be harsh on your eyes. You can protect your eyes by wearing sunglasses as they will help in preventing your eyes against any sort of damage. If your eyes come in contact with the colour, rinse them immediately to avoid infections. 
Moisturize around the eyes: Applying a good cream around your eyes will shield them from getting the colour into your eyes.
Avoid wearing contact lenses: You should refrain from wearing contact lenses while playing Holi. In case you cannot do without them, wear the eyeglasses. 
Use rose water: Rose water is known for its antiseptic and antibacterial properties and can do a great job in removing colour from the eyes. It can also be used to reduce irritation cause by the chemicals present in the colours.
Other health tips

Stay hydrated: Drink plenty of water before, during and after the festivities. Staying hydrated will not only keep you energetic but will also prevent your skin against the absorption of harmful chemicals. Drinking fluids will also ensure that all the toxins are flushed out of the body. 
Check your sweets for purity: Adulteration is at all-time high during the festive season. Therefore, make sure you buy your sweets from a reputed brand. In case, you are preparing your own sweets, buy your ingredients from a reputed shop, especially in case of products like khoya or if you can you even make that at home.
Keep your hands clean: Keeping your hands clean during the festivities can be a daunting task but since the colours used during Holi come as a fine powder and can easily get mixed with food, they can lead to different health problems. Make arrangements for snacks and drinks away from the festivity area. Make sure you wash your hands every time you touch the food.
Preventing asthma attacks: If you are an asthmatic patient, you must avoid playing with dry colours as they can aggravate breathing problems. The particles can enter your lungs and trigger an asthma attack. Asthmatic patients are also advised to carry inhalers, in order to avoid complications.
Apart from the above mentioned problems, these synthetic colors can also cause health problems like nausea, headache and vomiting in many people. Follow these tips and enjoy the festival to the fullest, while steering clear of all the harmful effects. So, forget all your worries and storm in the riot of colours. Be safe and be healthy! Have a great Holi!

This Holi Let's Paint The Town Red While Keeping Yourself Safe

High blood pressure can lead to hypertension, which is known to cause a variety of debilitating side effects or symptoms in the life of the patient. It can also lead to a number of related ailments which can affect the various organs of the body. The eyes are one of the organs that are most susceptible to this kind of spike in the body s blood pressure. Let us learn more about the connection between the two.

Retina: When high blood pressure goes untreated for a prolonged period, it can easily start to affect the blood vessels that can be found in the retina. The retina is the third or the inner most layer of the eye which is sensitive towards light and usually helps in refraction. This is where the light reaches so that one can focus clearly on an image. When the blood pressure of the patient stays high for a prolonged basis, there is significant pressure on the blood vessels in this part of the eye which can lead to an eye disease known as hypertensive retinopathy.

Symptoms: Symptoms of this eye disease include lack of clarity and focus when the eye comes to rest on an object, as well as headaches and other vision problems that typically spring from eye strain that one will go through while trying to focus even harder. It may be seen that the symptoms do not appear in the very early stages of this disease.

Diagnosis: The diagnosis of the condition is usually done by an ophthalmologist who will use an ophthalmoscope in order to project light towards the specific part of the eye so that the back of the eyeballs can be examined. The signs that the doctor will look for during the examination include narrowing of the blood vessels in this part of the eye, inflammation of the macula which is the central portion of the retina, and bleeding in the back of the eye. Also, the doctor will check for spots in the retina with the help of cotton swabs and exudates.

Treatment: The best and only way of treating this condition is by keeping one s blood pressure in control with the help of medication prescribed by the doctor.

Prevention: There are many ways of preventing the onset of this disease, including losing weight so that there is less pressure on the body. Also, one must stick to a healthy diet and exercise regularly after taking recommendations on the appropriate exercises from the doctor. Additionally, it is also important to see a doctor on a regular basis so that there is constant monitoring and regulation of the medicines and the blood pressure.

Blood Pressure - How it Affects Your Eye Sight?

Sunglasses are an important part of the accessories you use in summer or any time of the year. They help you to look fashionable and stylish and also make a pretty good style statement. But is that the only job of sunglasses? Or do they have something more to them? Here are a few reasons why sunglasses are more than just a style statement:


1. Decrease in eye problems: Generally, you use sunscreen to protect your skin from the Sun s glare. Similarly, sunglasses protect your eyes from the harmful UV rays of the sun. It is extremely important for you to protect the eyes so that the harmful UV rays cannot enter the sensitive eye tissue and harm them. If you do not use sunglasses, then you have a higher chance of damaging your eye tissue than a person who uses them regularly. Bear in mind that the strong UV rays can cause serious permanent damage to your eyes.


2. Protection from other environmental components: Not only is the sun harmful to your eyes, but also the wind can be extremely dangerous for them. Dirt, sand, dust particles can fly into your eyes even when just a breeze is blowing. On a windy day, damage can be much more. If you are wearing sunglasses when out on a windy day, they act like a shield to your eyes against the wind and the particles,which might enter your eye.


3.  Helps clear vision: It s often difficult to have a clear vision when out in the Sun. The bright sunlight doesn t give you the clarity in vision. Without protection, you will have reduced vision as the bright glare of the Sun might cause you discomfort in your eyes and limit your vision as you will have to squint in the bright light.


4. Helps prevent aging: Although it might sound a bit surprising, but wearing sunglasses actually helps in prevent aging. The bright glare of the sun causes you to squint and this causes the age lines to appear. So, if you wear sunglasses and your eyes are protected from the bright sunlight, then you will not be squinting anymore, and hence it will not cause the age lines to appear before time.


So now, before you think that sunglasses only make you look good, think again about how they actually do much more than that.
