Fact:Eye exercises will not improve or preserve vision or reduce the need for glasses. Your vision depends on many factors, including the shape of your eyeball and the health of the eye tissues, neither of which can be significantly altered with eye exercises.
As the eyes age, problems with vision become more common. Learn how to recognize the risk factors and symptoms of specific eye diseases— cataract, glaucoma, age-related macular degeneration, and diabetic retinopathy — and what steps one can take to prevent or treat them before your vision deteriorates.
Myth: Reading in dim light will worsen our vision.
Fact: Dim lighting will not damage our eyesight. However, it will tire our eyes out more quickly. The best way to position a reading light is to have it shine directly onto the page, not over the shoulder. A desk lamp with an opaque shade pointing directly at the reading material is ideal.
Myth: Carrots are the best food for the eyes.
Fact: Carrots, which contain vitamin A, are indeed good for the eyes. But fresh fruits and dark green leafy vegetables, which contain more antioxidant vitamins such as C and E, are even better. Antioxidants may even help protect the eyes against cataracts and age-related macular degeneration. Just don’t expect them to prevent or correct basic vision problems such as nearsightedness or farsightedness.
Myth: It’s best not to wear glasses or contact lenses all the time. Taking a break from them allows our eyes to rest.
Fact: If we need glasses or contacts for distance vision or reading, we should use them. Not wearing glasses will strain our eyes and tire them out instead of resting them. However, it will not worsen our vision or lead to eye disease.
Myth: Staring at a computer screen all day is bad for the eyes.
Fact: Using a computer does not damage our eyes. However, staring at a computer screen all day can contribute to eyestrain or tired eyes. People who stare at a computer screen for long periods tend not to blink as often as usual, which can cause the eyes to feel dry and uncomfortable. To help prevent eyestrain, we should adjust the lighting so it doesn’t create a glare or harsh reflection on the screen, it is advised to rest the eyes briefly every 20 minutes, and make a conscious effort to blink regularly so that our eyes stay well lubricated.
It can be a frightening moment. When the doctor diagnoses an eye disease such as glaucoma, cataract, or AMD, we immediately worry about losing our sight or becoming seriously vision-impaired.
It’s important to know what to do not only when disease strikes, but what to do before and after. We should know the warning signs and how a diagnosis is made. And the best treatment options for that.
The good news is, with the proper treatment decisions, those eye diseases can be addressed and controlled and their potential to compromise our sight can be halted.
Our eyes do change as we get older. That’s a truth we can do little about. It’s the consequences we can change. We we should learn all the facts about treating adult eye diseases.
Depending on the cause, watery eyes may clear up on their own. Self-care measures at home can help treat watery eyes, particularly if caused by inflammation or dry eyes.
Causes: Watery eyes can be due to many factors and conditions.
In infants, persistent watery eyes, often with some matter, are commonly the result of blocked tear ducts. The tear ducts don’t produce tears, but rather carry away tears, similar to how a storm drain carries away rainwater. Tears normally drain into your nose through tiny openings (puncta) in the inner part of the lids near the nose. In babies, the tear duct may not be fully open and functioning for the first several months of life.
In older adults, persistent watery eyes may occur as the aging skin of the eyelids sags away from the eyeball, allowing tears to accumulate and flow out.
Sometimes, excess tear production may cause watery eyes as well.
Allergies or viral infections (conjunctivitis), as well as any kind of inflammation, may cause watery eyes for a few days or so.
There may be some more other cause like due to different medication & other diseases.
Do your eyes itch after you’ve been near a cat? Do they puff up or run with tears when pollen is in the air? Allergies of the eye affect about 20% of Americans each year, and are on the rise. The same inhaled airborne allergens — pollens, animal dander, dust mite feces, and mold — that trigger allergic rhinitis (the familiar sneezing, runny nose, and congestion) can lead to allergic conjunctivitis (inflammation of the conjunctiva, the lining of the eye). It’s not surprising that people with allergic rhinitis often suffer from allergic conjunctivitis as well.
About 50% of allergic conjunctivitis sufferers, who tend to be young adults, have other allergic diseases or a family history of allergies. About 80% of eye allergies are seasonal; the rest are perennial (year-round). The symptoms are itchy and red eyes, tearing, edema (swelling) of the conjunctiva or eyelid, and a mucous discharge. Although it can be uncomfortable, you can rest assured that it is not a threat to your vision.
Diagnosing allergic conjunctivitis:
Allergic conjunctivitis usually can be confirmed by your doctor based on your symptoms. Testing is not usually needed to diagnose the condition, but skin testing (the same kind that’s done for other allergic reactions) may help identify the allergens causing your symptoms.
If your symptoms don’t quickly respond to treatment, see your doctor in case you have a different condition. Dry eye, in particular, can mimic the symptoms of allergic conjunctivitis.
Treating allergic conjunctivitis:-
Avoidance is your first line of defense. If you are allergic to cats, for example, avoid them (or at least don’t touch your eyes when near one), and wash your hands immediately after touching one. If pollen is your nemesis, keep your windows closed and an air purifier or air conditioner going in pollen season. Also, don’t rub your eyes, because rubbing causes cells in the conjunctiva to release histamine and other inflammatory chemicals, which worsens symptoms. Use artificial tears (available without prescription) frequently for relief and to dilute allergens in the eye.
If your only allergy problem is allergic conjunctivitis, then medicated eye drops would be your first step. You can start with an over-the-counter product, such as ketotifen eye drops (Zaditor, Alaway). The active ingredient is an antihistamine and a mast cell stabilizer, both of which can control the immune system overreaction that leads to your symptoms. Prescription-strength products that have similar actions are also available.
Allergic conjunctivitis can also be treated with over-the-counter oral antihistamines such as loratadine (Claritin), cetirizine (Zyrtec), and fexofenadine (Allegra), or the prescription antihistamines desloratadine (Clarinex) and levocetirizine (Xyzal). These are especially useful for people that have other allergy symptoms in addition to conjunctivitis.
For allergic conjunctivitis that is very severe and doesn’t improve with other medications, there are prescription eye drops that contain corticosteroids, such as loteprednol etabonate (Alrex, Lotemax) and fluorometholone (Fluor-Op, FML Forte). However, these eye medications should only be used under the guidance of an ophthalmologist.
General precautions & Alternative treatment of eatching & tearing eyes:
*Remember to keep their eyes free from dust and other particles that cause a blocking of the tear ducts.
*Wash the face and eyes frequently as this will also help to keep you refreshed. Washing your eyes frequently also removes the impurities from around the area of the tear ducts, keeping them free from blockages.
*You could also keep your eyes moist with the use of some mild eye drops. This will help in reducing the itchiness and the dryness that you experience.
*If you are going outdoors, make sure to wear some protective eye wear that help to keep impurities out of the eyes, thereby avoiding any irritability of the sense organs.
*Rose water is an excellent remedy to soothe dryness or burning sensations that are experienced in the eyes. Washing out the eyes in a capful of rose water will provide instantaneous relief.
*There are occasions where the optical nerve of the eyes and the muscles around the eyes have been strained, leading to dryness and itching, followed by a continuous flow of secretions. In order to relax the eyes and the relevant muscles, place slices of cucumber over the eyelids while you rest your eyes. The cooling effect of the cucumber slices will provide a great deal of relief to your tired eyes.
*On certain occasions, a warm compress, made by dipping a piece of towel into warm water and pressing it gently over the eyes will provide relief from symptoms of itching and continuous flow of tears.

Look at it head on to make sure it is perfectly symmetrical.
See if the tongue is laced with the shoe. That way it will not slip around placing the eyelets in contact with your foot. That is potentially injurious.
Make sure the sole “gives” by bending the shoe.
There should be a little space between your toe and the tip of the shoe. Shoes do not “loosen” with use. Your foot will get damaged before that happens. Nor will you “grow” into a shoe that is too large.
Buy your shoe in the evening when your foot is slightly swollen from the days activity.
The colour is the least important criteria. With use, all shoes eventually become the same colour. You may click to see : How to Choose Sports Shoes
Grey smoke Q: My hair is prematurely grey — I am only 29 years old. My mother says it is because I started smoking in college. Is that true?
A: Your mother is right. The nicotine in cigarettes does cause premature greying. That is however the least of the problems it causes. It also weakens your bones, precipitates heart attacks and causes cancer.
Stroke effect Q: My father had a stroke (brain attack) and now he mumbles his words. Food drools out of the side of his mouth when he eats. He also cannot close one eye.
A:Your father has lost the use of one side of his body. Paralysis of the eyelid muscles prevents him from closing his eye fully. Similarly, the muscles for speech and swallowing are affected.
He will improve to some extent with physiotherapy. You need to make sure that he does not have a second stroke by treating any pre-existing disease like diabetes, hypertension or high lipids that caused the first stroke.
You need to protect his eye by closing it manually, placing a gauze piece over it and taping it shut with medical tape.
Facial paralysis Q: My forty-year-old aunt developed isolated paralysis of one side of the face. She opted for ayurvedic treatment and recovered. She is not diabetic nor does she have high blood pressure. What was wrong with her?
A: She seems to have developed a condition called Bell’s palsy, paralysis of the facial nerve. Quite often it is due to an infection with the Herpes virus. In 80 per cent cases recovery is spontaneous and complete. This is probably the category to which your aunt, fortunately for her, belonged.
Lens safety Q: I want to use a pair of contact lenses to change the colour of my eyes. Is it safe?
A: These are called novelty lenses as they only have cosmetic value. If novelty contact lenses are not properly fitted or if care instructions are ignored, they can cause corneal damage and loss of sight. Eye infections can occur if the lenses are not thoroughly sterilised prior to each use.
This seems a high price to pay for an altered appearance. After all, beauty is in the eye of the beholder.
A: It depends on how dirty your hair becomes, but three times a week is about average. There is no need to use a lot of shampoo. About a Re 1 coin sized dollop is sufficient. You may click to see : How often should I wash my hair?
Fast food Q: My son loves instant noodles. He eats them 3-4 times a day. He is 4 years old.
A: Noodles are a good snack once or twice a week, but they should not substitute for good wholesome home cooked food. Some times the instant variety of noodles contains preservatives or ajinomoto. Both these ingredients are best avoided in children’s food.
Rash shave Q: I got a shave at a barber shop and now, after two weeks, I have developed boils and rashes all over my beard area.
A: This is a very common infection which is either due to the bacteria S. aureus, or a fungus or due to ingrowth of thick beard.
It responds well to hot fomentation, cleansing with a bactericidal soap and local application of ointment. A dermatologist can usually determine accurately whether the infection is fungal or bacterial and prescribe the appropriate ointment. Applying steroid cream will worsen the condition. It usually clears up in a few weeks but can recur. It is probably better to shave at home.
The collagen-based implants could be an alternative to cadaver corneas. A preliminary test shows that they restored vision as effectively as the latter and did not require anti-rejection drugs.
An experimental synthetic cornea implanted in 10 patients may be a potential alternative to cadaver corneas for curing vision loss due to corneal inflammation and scarring, researchers said .
Eye surgeons currently use primarily cadaver corneas for transplants, but that requires the use of anti-rejection drugs and presents a risk of infection. Plastic corneas can also be used, but they present other problems and are generally tried only when tissue transplants have failed.
The new artificial corneas use collagen produced in yeast as a scaffolding that allows cells from the recipient to grow into the graft so that it mimics the original tissue. The two-year preliminary test showed that the biosynthetic corneas restored vision as effectively as cadaver corneas, did not require anti-rejection drugs and allowed normal tears to form.
“This is a huge breakthrough,” said Dr. Francis W. Price Jr., founder and president of the board of the Cornea Research Foundation, who was not involved in the research. “It still has to go through additional studies … but it shows a lot of promise.”
An estimated 5 million people worldwide suffer corneal damage from trachoma, an eye infection caused by the bacterium Chlamydia trachomatis, and another 1.5 million to 2 million people develop it as a result of ulceration and trauma. In the United States, about 42,000 cadaver cornea transplants are performed each year and another 10,000 corneas are exported to other countries, according to Marianne O’Connor Price, executive director of the Cornea Research Foundation.
“The U.S. is very fortunate that everybody who needs a transplant here is able to get one, but there is definitely a big shortage around the world,” she said. “Even people here could benefit if there was a synthetic cornea that eliminated the chance of rejection.”
The new study, reported Wednesday in the journal Science Translational Medicine, used biosynthetic collagen produced by FibroGen Inc. of San Francisco. A team headed by Dr. May Griffith of the Ottawa Hospital Research Institute in Canada molded the collagen into an artificial cornea and demonstrated that it worked in animals.
Dr. Per Fagerholm of Linkoping University in Sweden then implanted the corneas in one eye of each of 10 Swedish patients with central corneal scarring. The researchers found that, after two years, no complications developed and, with the use of contact lenses, vision was as good as with cadaver transplants. Contact lenses are normally used with the latter as well.
The study is the first to show that an artificially fabricated cornea “can integrate into the human eye and stimulate regeneration,” Griffith said.
Griffith said her team was now building a clean room to manufacture more of the corneas and that she hoped to begin larger clinical trials after the first of the year with about 20 to 25 patients.
When implanted with contact lenses that they previously couldn’t tolerate, patients saw as well as a similar group of patients who had received standard corneal transplants.

“Over the years, it has been found that Retinopathy of Prematurity (ROP) has been found in children with birth weight of about 1,500 grams and born within 32 weeks of pregnancy,” Rajvardhan Azad, chief of ROP unit in the AIIMS Opthalmology department, said.
