Eyeglasses and contact lenses are both used for vision correction. Both of the options have their advantages and disadvantages but a number of factors like lifestyle, comfort and age etc. are important while deciding which one to choose. Here is a list of the fundamental differences between using spectacles and using contact lenses:

1. Distance from the cornea
Lenses are worn directly on the eye and are in constant physical contact with the cornea while glasses are worn over the eyes. Contact lenses may cause infections in the eye because the user has to touch the eye in order to wear them and to take them off.

2. Difference in vision
Since the lenses of spectacles are a little distance away from the eye, vision can be slightly distorted but contact lenses can provide natural and accurate vision. Also, side vision is not improved by glasses as you have to turn your head to see what is beside you. The contacts move around with your eyeballs and the peripheral vision is in focus.

3. Ease of use
Some people find eyeglasses difficult to use because of the constant weight on the face and the obstruction caused by the frames of the glasses. There may also be a constant need to adjust the frames. Often eyeglasses slip down the nose when you sweat or engage in rigorous physical activity. Contact lenses are free from all these hassles - they are not distracting or obstructive and so they are extensively used by dancers and athletes. Spectacles is very uncomfortable to wear during the rains or in humid weather because they fog up.

4. Infections and complications
Contact lenses can get displaced inside the eye and they can be difficult to reposition. They also cause the eyes to itch and water if you wear them for a very long time at a stretch or if tiny dust particles enter your eyes. The use of eyeglasses is far more flexible in this respect - they can be removed in case your eye itches or burns, but regular use of glasses causes dark circles and bags under the eyes.

5. Aesthetic differences
People often prefer contact lenses as they do not change the physical appearance - they help you look natural and you can also use colored lenses to change the color of your eyes. Glasses may look slightly unnatural but some people also prefer them for the fashion quotient.

Lens Vs Specs

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!

Natural Remedies For Better Eyesight

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.
