Cataract is clouding of clear natural lens present inside the eye, this is a major cause of decreased vision in elderly. Cataracts can occur in one or both eyes, usually developing very slowly. Things look blurry, hazy, less colourful and less sharp with cataract. 

Most cataracts are related to ageing, however many other factors can either increase the rate of formation or cause cataract formation. 

Causes of Cataract Formation-

Ageing: Most common cause. As the proteins present in the lens of the eye degenerates over the years ( just like any other organ) cataract is formed. If you are having Diabetes or hypertension, the rate of formation gets accelerated.

Radiation: Prolonged exposure to ultraviolet rays, especially UV-B rays, results in cataract in your eyes. Wearing sunglasses in the daytime helps in slowing down the process of cataract.

Genes: Many genetic disorders can result in congenital cataract ( cataracts present since birth) or early formation. Like in Lowe syndrome or Down's syndrome. 

Lifestyle Choices: Cigarette smoking, long hours of sun exposure regularly, antioxidant, poor diet etc. are responsible for the onset of cataract.

How To Detect Cataract?

Certain signs and symptoms suggest the existence of cataract in the eye. Depending on the type and level of cataract, problems in vision occurs. The main symptom is foggy cloudy vision as if seeing through a dirty glass window. 

Other Symptoms are- 

inability to see clearly in bright light (during the day) which becomes better in dim light ( evening and night) and vice versa. 
watery, tired eyes - mild pain in and around eyes. 
yellow tinge in vision 
Halos around light bulbs or bright light. 
If you are experiencing above symptoms and having problems in viewing things clearly, visit an ophthalmologist and get your eyes checked.

Foggy and Cloudy Vision - A Sign Of Cataract?

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

A common headache can have a number of reasons behind it, such as defective vision, hetrophoria or convergence deficiency, etc. Now, the question arises as to how they can cause headache. Read on to know more...

Q. Why should defective vision cause headache?

To attain a perfect vision, eyes with defective vision have to make sustained extra efforts, which results in headache. Even if the refractive error is very small, it can be the cause of headache. More prolonged the working and smaller the print, higher the incidence of headache.

Q. Can this occur at all ages?

Yes, it can occur at all ages. However, with age, the resistance decreases and hence elderly people are more prone to get headache. More the use of computer, mobiles, TV or prolonged studies precipitates headache

Q What is Hetrophoria?

Normally, both eyes always remain parallel, but in some cases, eyes have slight tendency to develop minor squint, may be convergent or divergent. This is called Hetrophoria or Latent squint. Such patients have to take extra strain to keep the eyes straight

Q. What is convergence deficiency?

For reading, both eyes have to converge and if there is weakness of convergence, extra strain has to be put on the eyes, which cause headache.

Q. What is the ideal method of refraction in young patients, I,e below 40 years?

Ideal method is to dilate the pupil with Tropicasyl plus drops. This has the advantage that the doctor can see the retina and Optic Disc. This is important to exclude any involvement of brain as the cause of headache. It also relaxes accommodation and hence provides correct refraction. In cases of Hypermetropia, it is extremely essential to dilate the pupil.

Q. What is the role of Autorefractmeter (a computer) in refraction?

It is a very important instrument to provide correct refraction, but it cannot be totally relied upon. Some opticians rely on it and give wrong numbers.

Q. What is acceptance Test?

You have refracted the eyes with Autorefractmeter or Streak Retinoscope but exact power is what a patient accepts. This is very important.

Q. What is astigmatism?

There is a difference in refraction in different meridians and it is important that a cylinder number is prescribed in correct axis. This is a difficult task and needs lot of experience.

Q. Is it important to correct astigmatism?

To relieve headache and strain on the eyes, it is very important that exact cylinder is prescribed.

Q. What is the role of exact centring of Optical Lenses?

You may give correct number, but if the centre of the Optical lenses and cornea do not coincide, satisfactory results are not obtained. To dispense correct lenses is a big art and the Optician must be qualified and well experienced.

Q. Does the quality of lens affect the visual comfort?

Yes, it is important that quality of lenses should be good, preferable fibre lenses which are Ant reflect coated. Crizal coating with capability to block the UV rays are very popular.

Conclusion: Refractive errors are important cause of headache and needs proper examination of the eyes, preferably after dilating the pupil. Astigmatic error even if too small may be the cause of headache. Spectacle dispensing is an art and a patient must select proper optician. Spectacles if advised for constant use must be used constantly to get full relief.

Protect Your Eyes While Working. 7 best ways.

An eye allergy or allergic conjunctivitis is a condition that strikes when certain substances irritate the eyes, which can cause a reaction. This reaction has varied symptoms starting from inflammation to watering and even redness and an itching sensation. So how can you tell if you have an eye allergy? this article will tell you all you need to know!

Causes: to begin with, this is an immune response that happens when the eye comes in contact with substances like dirt, grime, pollutants, pollen, nettle, pet hair, smoke, mold and more, which may cause irritation. These are typically known as allergens. The immune system takes these allergens to be invaders and begins attacking the same by releasing chemicals that cause these allergic reactions. Also, an eye allergy may be a symptom or outcome of other conditions like asthma, hay fever, or even eczema.

Symptoms: the eye usually bears a pink or red appearance when the patient is suffering from an eye allergy. Also, watery eyes are a common sight during this condition while scaling around the eyes may also take place. Further, itching and burning sensation may be felt by the patient and swelling or puffiness can be seen. The symptoms may afflict one or both eyes. The patient may also have a runny nose or stuffy nose as well as nasal congestion.

Difference between eye allergy and pink eye: conjunctivitis or pink eye is usually caused due to bacteria or a virus that spreads infection in the eye. But eye allergy is caused due to a response of the immune system that leads to an allergic reaction. While the pink eye may be a contagious condition, an eye allergy is not.

Diagnosis: the diagnosis of an eye allergy will be done with the help of various tests conducted by an ophthalmologist. The skin prick test will help in introducing allergens to find out if the spot gets raised or suffers from inflammation. Also, the doctor will check for other ailments like asthma and eczema.

Treatment: there are varied methods of treating this condition. To begin with, the doctor may prescribe medication like decongestants and antihistamines as well as steroids for more severe and persistent cases. Also, injections may be prescribed in order to do away with the allergic reaction and eye drops containing olopatadine hydrochloride may also be used.

Home remedies: staying away from allergens and using a warm and clean washcloth over the eyes, for a few minutes every day, may help in relieving the painful symptoms of the condition.

Do not forget to consult your doctor before you try any natural or home based remedies.

Are You Suffering From Eye Allergy?

Hypertension is a killer disease whose symptoms develop late when the damage is in advanced stages. Hypertensive Retinopathy is one such disease.

It damages the retina of eyes. Since retina is responsible for vision formation, Hypertensive Retinopathy can result in loss of vision. It is of grave concern that in most cases, Hypertensive Retinopathy is diagnosed later.

This is due to the fact that there are often no symptoms in the early stages of the disease. In some cases, where symptoms do manifest, patients may experience pain in the eyes, reduced vision, or headache.

What Happens in Hypertensive Retinopathy

People suffering from long term hypertension are susceptible to Hypertensive Retinopathy. Long-term hypertension affects the small and narrow blood vessels that join arteries to capillary blood vessels taking blood to different parts of the eye. These blood vessels become narrow with time if hypertension in the eyes continues unabated. This narrowing is more common in young adults compared to older people. Such unabated systemic hypertension also leads to leakage of fluid. This is why in some cases of Hypertensive Retinopathy, patients may experience exudation. Ultimately, Hypertensive Retinopathy may lead to damage to retinal blood vessels.

Risk Factors

Long standing hypertension is the number one risk factor for Hypertensive Retinopathy. People who are suffering from longer hypertension become most susceptible for this ailment.

However, studies have shown that hypertension for more than 5 years can even make people susceptible to this ailment.

Diagnosis

Diagnosis is done by Funduscopic Examination. The doctor would look at the eyes of the patient through an Ophthalmoscope which has different lenses. The Ophthalmoscope illuminates the retina and the doctor looks at the retina with different lenses. He can get a view of the retina, including blood vessels and optic nerve disks.

Findings of Diagnosis

For a person suffering from Hypertensive Retinopathy, this examination is likely to show:

Constriction of the arterioles.

Changes in the walls of retinal blood vessels.

Flame-shaped hemorrhages in the retina.

Yellow and hard exudates.

Spots in the shape of cotton wool.

Swelling of the optic disc.

Treatment

The primary treatment for Hypertensive Retinopathy is controlling blood pressure of the eyes. Some lifestyle changes like reducing the intake of salt, avoiding tobacco, etc., may bring down or control systemic hypertension in the eyes. In many cases, doctors may just recommend lifestyle modifications. Nevertheless, it completely depends on the extent of the damage and whether or not there is any fluid accumulation.

If the doctor feels that lifestyle modification is not enough, he may go for medicines that help the patients to control blood pressure effectively.

If the problem is in advanced stages and there is fluid accumulation behind the retina, the doctor may go for Intravitreal injection or Laser Therapy to control the edema.

Conclusion

Eyes are one of the most significant part of the body, this is why it is important for people to take care of it. In case of disease like Hypertensive Retinopathy, one must consult a doctor before opting any treatment or medicines.
