Presbyopia is one of the most common eye diseases. It usually occurs around middle age and is characterized by reduced or blurred vision. Colloquially, presbyopia is the loss of near vision and can be corrected by using optical instruments such as glasses and lenses. It is estimated that a billion people across the world suffer from this eye disease.

Symptoms of Presbyopia

Presbyopia is typically associated with blurry vision, especially when reading, working on computers, etc. People suffering from it usually have to hold reading objects at a distance to read them properly. If you find yourself reading a book by keeping it at an arm’s length, you know that you should see an opthalmologist for presbyopia treatment.

Causes of Presbyopia

Presbyopia is largely age related. Unlike nearsightedness or farsightedness, which are affected by genetic factors, presbyopia is caused by the gradual loss of flexibility of the eye lens. With age, the muscles controlling the eyes tighten up, losing their elasticity. This means that the eye lens has to try harder to focus on close objects. Also, the proteins that make up the eye lens harden up with age, leading to loss of flexibility. All this contributes to presbyopia.

Treatments and Cures of Presbyopia

The most common and highly effective cure for presbyopia is the use of corrective optical instruments such as glasses and lenses. For patients suffering from presbyopia alone, reading glasses are an apt solution. These reading glasses can be purchased over the counter easily.

Those suffering from nearsightedness as well as presbyopia, farsightedness, etc. can opt for bifocals or progressive addition lenses (PALs). Bi-focals are essentially glasses that have corrective lenses for both near and far vision. Progressive Addition Lenses are the same as bi-focals in function, but offer a more gradual transition between the near and far vision lenses. There is also no vision transition between the two on the surface of the lens.

With age, the flexibility of your eye lens will further deterioate, so you will need to periodically increase the power of your contact lenses/glasses. Periodic visits to the eye doctor or optometrist are advised to make sure that you are using the appropriate corrective devices.

Another option for presbyopia patients is to opt for surgery. LASIK is one of the most common options and is highly effective. It is also quite affordable and is non-invasive as well.

Along with LASIK, there are several experimental treatments that haven’t quite achieved the same success rate as LASIK. One experimental treatment, for example, includes injecting an elastic gel like substance that will replace the natural eye lens. However, since most such treatments are in the experimental stages, it is recommended that you opt for LASIK if you do plan on getting surgery done for this eye disease.

Eye strain is one of the most common eye related complaints that people have. It may occur due to a number of reasons and is very easy to cure in most cases. Medically, it is called asthenopia. With the increasing use of computers in homes and workplaces, instances of eye strain have risen sharply.

Also called astheopia, it is a symptom rather than an eye disease. It usually occurs when eyes get tired and fatigued due to intensive use. It manifests itself as discomfort in looking at things. Most people have experienced eye strain in some form or the other. It is not a serious condition and can be treated through rest alone. However, if eye strain occurs frequently, it may be taken as a sign of other more serious eye diseases.

Symptoms

The common symptoms of eye strain are easy to identify. They include discomfort in the eyes, dryness or conversely, mild tears, soreness, and an inability to concentrate on things. Other symptoms include pain at the back of the neck and temples, headaches, and blurred double vision.

There are no medical tests to determine the severity or degree of the strain; it is subjective, varying from patient to patient. It is also lifestyle dependent – those used to spending long hours working before computer screens or reading will suffer less than others.

If eye strain does occur frequently, then it is advised that you consult your ophthalmologist as it can be a symptom of an underlying eye disease.

Causes

Eye strain is typically caused by intensive use of the eyes for a long period of time. Visually intensive tasks such as reading (especially if the print is small), watching television, working with computers, playing video games or driving are common causes of eye strain. Working in dim light can also cause tightening of the muscles in the face around the eyes, leading to eye strain.

In some cases, the strain may be a symptom of underlying ocular conditions such as presbyopia, nearsightedness or farsightedness. Strain in those already suffering from these conditions can be an indicator of the need for higher power corrective optical instruments (glasses or lenses).

Treatments

Treating most forms is as simple as taking a rest for a few hours. Relaxing the eyes naturally relieves them of any built up stress and fatigue. Certain exercises such as closing the eyes for a few minutes, massaging the temples, etc. can also provide temporary relief. If you are going to spend long hours before a computer or on other visually intensive tasks, it is recommended that you take periodic breaks.

You can also reduce the intensity or frequency of eye strain by working in more suitable conditions. If using computers, try using a LCD or TFT monitor instead of a CRT one. Make sure that you work in well-lit conditions and always maintain a healthy distance between yourself and a computer or television screen. Take a break every hour and stretch your arms, back and shoulders to relieve your body of built up stress.

If strain leads to excessive dryness of the eyes, you can get an over-the-counter eye drop for relief. In almost all cases, eye strain is not serious and can be easily cured through rest, but if it persists for a long time, it may be wise to consult an ophthalmologist.

An eye disease caused by pathogens such as bacteria, fungi, viruses and other microbes is called an eye infection. Eye infections can range from the common conjunctivitis to rare allergies. Eye infections can vary in the degree of severity, but in most cases, they are easy to cure.

Eye infections are usually transferable from one person to the other. They can strike anyone regardless of their ocular health, though they tend to be more common among those who wear contact lenses. This is largely due to infections in the contact lens itself.

An eye infection may be caused either due to direct contact with pathogens through eye wear, eye lids, etc., or through remote contact through sinuses. Infections can be caused through infected eye wear, eye surgery, injuries or trauma, vitamin or mineral deficiencies, or immune deficiencies as well.

Symptoms for various infections differ. The most common type of infection – that is, bacterial conjunctivitis – results in red, swollen and itchy eyes. There is frequent discharge of liquid and constant irritation. The eyes may also appear swollen with excessive tearing.

Other infections, such as blepharitis typically has similar symptoms. The eyes turn red, there is excessive tearing, and constant discomfort. Blepharitis also involve light and glare sensitivity and a burning sensation. If your eyes turn excessively red or are painful, it is best advised to consult an opthalmologist immediately for proper diagnosis, especially since most eye infections are similar in immediately discernible symptoms.

Eye infections can strike anyone but tend to be more common in children or those with poor hygiene or health. If you’ve undergone any eye surgery recently, chances of an infection increase manifold. Trauma or injury can also lead to an eye infection, so proper care is a must. Further, since most infections are highly contagious, you should avoid contact with any patient.

An eye infection can occur through contact with an infected surface, whether it is a hand or a pair of glasses/contact lenses. You should take care to always wash your hands before touching your eyes. You should also never share eye make-up, glasses or contact lenses with anyone, let alone an infected person. You should also avoid using towels, handkerchiefs, etc. used by an infected person.

Further preventive measures include wearing eye protection whenever you are out in the sun, not sharing any eyewear cleaning solutions, and avoiding exposure to contaminated or dirty water.

Treatment is infection dependant and correct diagnosis is the first step. Some infections such as conjunctivitis are very contagious and require the patient to remain in isolation. Most treatment courses involve an antibiotic eye-drop or ointment along with antibacterial medication ingested orally. Most doctors will also advise warm compresses applied directly to the eyes frequently, which helps remove any debris from the eyes and reducing bacteria.

Eye infections are easily curable in most cases, though the biggest challenge is containing their spread as they are highly contagious. If you do get affected, it is best advised to stay in isolation for a few days until the symptoms reduce.

However, if you are planning to buy glasses on-line, then you might need to know your own PD and since it could be bothersome to visit the doctor to only have the measurement taken, it will be best if you can do it yourself.

Here are some techniques on how you can determine your PD:

Of course, the initial option would be to go to an eye doctor and pay out a small amount of fee to have your PD taken. But because we’re looking at doing it yourself, here are some very simple steps:

1. Request a buddy to take the measurement for you. It would be rather challenging to get the measurement yourself especially if you’re aiming for accuracy.
2. Get a ruler (one which includes millimeters) and have your companion stand in front of you, holding the ruler horizontally under your pupil (or directly in front of your eyes).
3. Using a non-permanent marker, have your friend indicate the center of each pupil on the ruler.
4. Calculate the length between the 2 dots.

You can also try to download a printable ruler that is exclusively used to evaluate PD online. A lot of optical shops give their services online so you can locate easily website that gives a free download of the printable ruler. Again, you’ll require a friend to help you with the measurement.

1. After printing the ruler from the website, request your pal to stand at arms length away from you.
2. The printable ruler would often have a zero value. Request your buddy to put the ’0′ value in the center of the left pupil and assess through the middle of the right pupil. It is crucial that your buddy maintain the printable ruler right across your face to acquire a precise measurement.

When getting your PD, you must ensure that you’re looking straight to receive an accurate measurement. You can even do the measurement many times for additional reliability and have other buddies calculate it for you. After getting a number of measurements, find the average of values that your buddies have listed and list it as your PD.

Remember, while you are taking your rating, you should be as precise as you can because your PD will significantly determine the length of every frame for your eyeglasses. For additional precision, have a companion take the measurement for you and have it taken numerous times so you can be sure that your upcoming glasses will be finest fitted for you.

Causes for Poor Vision

One reason you may be experiencing a loss in vision is staring at a computer or television for longer periods of time. Decreasing the amount of time you spend at the computer is one way to correct vision – although this is not the only way. Wearing glasses may correct vision for awhile; however, even glasses and contacts can be harmful to the eyes.

The reason for this is that they actually weaken the eye muscles; this is why doing eye exercises can improve eyesight naturally because you are strengthening the muscles within the eyes. Just like any muscle in the body – if you don’t use it, you’ll lose it. Weak arm muscles make holding heavy objects difficult; just like weak eye muscles cause poor eyesight.

Improve Eyesight Naturally

Wearing glasses or contacts is not a way to improve eyesight naturally, because you are introducing a foreign object into your eyes. Not only does this weaken muscles, it can cause unwanted bacteria to enter the eye, which may actually cause blindness. If you increase the amount of eye exercises you do per day, then you will drastically improve eye vision without the help from an optician.

Here are just a few exercises that can help improve eye vision without doing much work at all:

Blinking – Zooming – Tracing – Focusing – Palming

Blinking is something you do naturally; however, increased focus at the computer or television can decrease the amount of time you blink. Each time you blink, you refresh your eyes, which reduces a certain amount of eye strain. Take a break and blink every three or four seconds for two minutes. Afterwards, your eyes should be more relaxed than before. It’s hard to believe that something as simple as blinking can help correct vision.

Zooming and focusing are very similar, and both exercises are done by placing your thumb in front of you and moving it closer and further from your eyes. Not only does it strengthen your eye muscles, it also improves your ability to focus.

Tracing can be done to improve eye vision by imagining a figure-eight in front of you and tracing it with your eyes. This exercise will help strengthen your eyes, as well as improve eye flexibility. It will be hard at first, but it will become easier the more you practice it.

Palming is a simple way to relax and improve eye vision also. By placing your palms over your eyes and resting your elbows on your knees, you are giving your eyes a chance to relax and refocus. All of these eye exercises are ways to correct vision without surgery and without the need for glasses or contacts.

More and more of us are now working at a computer all day and this is having a harmful effect on our eyes & our general health. How do you feel after working in your office all day? Are you fatigued or tense? Are your eyes tired? Do you suffer from migraines regularly? If so, there’s a good chance your work environment is contributing. The combination of staring at a computer screen all day, and poor office lighting could be having a detrimental effect on your vision. This can lead to headaches, migraines, blurred visions and dry eyes.

Computer-induced eyestrain can damage your vision as it causes the muscles in the eyes to become less flexible, and without correct lighting this damage can be made worse. Following a few simple tips could help combat the damage to your eyes:

Firstly, make sure you take regular breaks. Look up from your screen every few minutes and focus on something across the room. Every hour, take a few minutes to leave your computer and walk around – for example you could make a cup of tea or go to the photocopier.

Many of us tend to gaze at the screen for long periods of time, particularly if we are working to a deadline or suffering from stress. Try to refrain from doing this, and remember to blink regularly – between 10-15 times a minute is average. If you suffer from dry eyes, use eye drops to keep them moist.

Keep a good distance between yourself and the screen – at least 25 inches ideally. The screen should be tilted slightly upwards so that you are looking down at it.

Bad office lighting can also be harmful to your eyes. The standard for office lighting is 500 lux. Also, make sure that there isn’t a direct glare onto your eyes from either an overhead light or natural sunlight. You can test how much glare you receive by holding you hand over your eyes and seeing the difference. Use curtains or blinds or move your desk position to reduce glare. Also, make sure there is no reflected glare shining onto your computer screen. If necessary, use an individual desk lamp to cast extra light over your documents, but make sure it doesn’t shine in your eyes or those of people sitting around you.

Visit your optician at least every 2 years. It’s important to keep up to date with your appointments, as your optician can tell a lot about your overall health from the condition of your eyes. If you are prescribed glasses for computer use, make sure you wear them, and purchase lenses with an anti-reflective coating. If you are classed as a computer user you are entitled to a free test, and may even receive help towards the cost of glasses.

Finally, ensure you maintain a healthy diet with plenty of water, green leafy vegetables and fresh berries to help support your eye health. Natural supplements such as gingko biloba, and lutein have also been shown to keep your eyes healthy.

By sticking to these simple guidelines, you can improve the health of your eyes, reduce migraines and feel happier at work.
