Dealing with Eye Diseases: Cataracts and Glaucoma
It can be hard dealing with eye diseases. They not only affect your daily vision but also your lifestyle. Many eye health problems can go undetected and untreated for years, leaving you with irreversible effects. It is vital to take care of your eyesight. Cataracts and glaucoma are two of the world’s leading eye diseases and many people are unaware of the signs to help treat them and prevent loss of vision.
Cataracts
Cataracts is the clouding of the eyes behind the iris and the pupil and is one of the most common causes of vision loss around the world. Related to aging, cataracts occurs when the protein in the eyes clump together to cause a clouding effect. Your vision slowly becomes duller and blurrier which will lead to simple things such as reading harder to do. Besides age, factors that may cause cataracts include:
– Exposure to too much UV radiation
– Diabetes
– Obesity
– Smoking
– Large amount of alcohol consumption on a regular basis
Early treatment may save your sight and if you find that you have any of the above symptoms, it is vital that you see your eye care professional to arrange the best possible treatment.
Depending on the severity of the cloudiness in your pupils will determine what will be the best treatment is for you. If caught early, most people will only need to wear glasses to help their vision. When glasses cannot help your vision any longer, your eye care professional may decide that you need to have surgery. Cataracts surgery entails the removal of the cloudy lense, which is replaced with an artificial intraocular lense.
Eating healthy can help prevent cataracts. Vitamin C, vitamin E, lutein and the zeaxanthin found in many fruits and vegetables may be able to help. Always wear sunglasses when outside to protect your eyes from the harmful rays and glare.
Glaucoma
Glaucoma is another common cause of vision loss around the world where the optic nerve at the back of the eye is slowly destroyed. Blockage of circulation or drainage weakens the nerves to your eyes causing this disease loss of vision. Due to the poor blood supply, the fibers to your eyes are damaged and it can slowly destroy your vision partially or completely. Unfortunately when the damage is done it is irreversible and unfortunately permanent.
Some may experience full vision loss and some may only have side vision loss depending on what fibers are damaged. There are many warning signs to watch out for with this eye disease including, excess tearing, unusual adjusting to dark rooms, distorted vision, difficult focusing, double vision, dry and itchy eyes. They may not all lead to glaucoma, however any of these signs must be taken seriously and you should seek medical attention straight away.
For those that do not have any signs and symptoms, it is still advisable to have regular check ups at the age of 40 and above. Unfortunately when the damage is done and vision is lost, glaucoma is irreversible. If caught early it can be treated with eye drops and surgical procedures including lasers, which will prevent loss of vision.
Although anyone can get glaucoma, there are some people higher at risk. Those in this category are:
– Older people
– People who have diabetes
– People who have had previous eye injuries
– Excessive use of steroids
– Family history
Dealing with cataracts and glaucoma along with other eye diseases can be quite difficult and challenging. Slowly it can become worse and lead to vision loss and blindness, which can make it can extremely difficult to live the same lifestyle. Prevention is always better than cure so whether or not you have any symptoms of eye diseases, have a check every twelve months to ensure that you are healthy. The earlier signs of detection will allow you to treat the issue with the best possible outcome.
The Relationship Between Diabetes And Eye Problems
Sight might seem like a simple function, but the science behind it is quite complex. When you look at something, light bounces off the object and into your eye, where the cornea and the lens help you to focus and place the light signals onto the retina. The retina, which has a complex blood vessel network, is a very delicate tissue with a high sensitivity to light. The retina has the ability to convert light signals into electric signals, a form that can travel to the brain through the optic nerve. The brain thereafter interprets the electric signals and helps an individual to ‘see’ what he or she is looking at.
Common eye conditions that can result from diabetes:
- Diabetic retinopathy – Here, diabetes damages the blood vessel network in the retina, resulting into serious eye complications.
- Cataracts – Here, the long-term result of having diabetes can result in the development of a cloudy substance in the lens.
- Blurring of vision – The fluctuation of the blood sugar levels in the body caused by diabetes can result into the fluctuation of blurring depending on how high or how low the sugar levels are.
Focusing on Diabetic Retinopathy
Diabetic retinopathy is one of the most serious eye conditions that can result from diabetes. Presence of the disease in the eye will lead to either blocking of the blood vessels to the retina or leaking of blood in the retina, a situation that will lead to serious vision problems. The type of diabetes and its seriousness will dictate the extent to which an individual’s vision will be affected. Type 1 diabetes and type 2 diabetes will lead to 40% and 20% chances of getting retinopathy respectively.
Diabetic retinopathy develops through the following stages:
- Background diabetic retinopathy – Here there is a very mild effect on the blood vessel, leading to slight bulging and slight fluid and blood leaks. At this point, the disease has no effect on an individual’s vision.
- Proliferative diabetic retinopathy – This is the blocking of the blood vessels in the retina, leading to lack of oxygen in some sections of the retina. The eye will start growing more blood vessels to restore the normal oxygen supply, but the vessels that grow are weaker and susceptible to bleeding and result in hemorrhages that obscure vision or lead to total loss of sight.
- Diabetic maculopathy – Here, diabetes affects the macula, a condition that associates itself with the above forms of retinopathy. This condition affects the central vision, making it hard for an individual to see details clearly.
How to fight diabetic retinopathy
The best way to fight diabetic retinopathy is to control the diabetes in the body. Therefore, visiting a medical professional is at the top of the list, since he or she will help you to:
- Go for retinal screening on a regular basis, since this will help detect the condition early and treat it before it gets worse
- Control the glucose levels in the body
- Maintain a healthy blood pressure
- Check the levels of cholesterol you take in
- Keep fit and give up smoking
The treatment of the condition
Thanks to the advancements in the medical field, it is possible for doctors to treat diabetic retinopathy using laser technology. This treatment works best for patients who discover the condition early enough, thereby placing emphasis on the need for routine eye checkups. The advantage of laser treatment is that no cutting is involved, therefore no blood bleeding will occur, and it can prevent new blood vessels from growing in the eye.
However, this laser eye treatment will not always result in improving a patient’s eyesight, though it will undoubtedly prevent the eye from becoming worse. Laser eye treatment for diabetic retinopathy can take either of the following procedures:
- Localized laser treatment – Here, the laser treatment seals leaking blood vessels, and reduces the level of swelling in the retina. This treatment is fast, and has no negative effect on a patient’s vision.
- Pan-retinal laser treatment – This treatment is more extensive compared to the localized laser treatment. This procedure seeks to treat a large section of the retina where new blood vessels are growing. The extensive nature of this treatment can lead to loss of peripheral vision, and can affect color perception and night vision.
The above treatment can result in a bit of eye discomfort, therefore using painkillers and eye drops will help to bring relief. The brightness of the laser can affect a patient’s sight for a few hours, but the situation improves after a while.
Eye Exercises: Protect Your Vision and Impress Your Eye Doctor
Eye glasses are a wonderful way to see the world clearly and with precision. Optometrists do wonderful work to ensure that we all have healthy, strong eyes that will serve us for the long haul. That’s why It is very important to maintain a regular eye check-up schedule and to develop a relationship with the optometrist to allow he or she to develop a relationship with your unique eyes.
However, eye care includes more than testing your vision and eye health. There are simple exercises we can do to maintain, and even improve, our vision over time. Of course, nothing natural is a quick fix. As with the use of natural medicines, exercises for any aspect of the body takes time, effort and consistency. With a little effort it is indeed possible for your to strengthen and maintain your eyesight.
Take a Computer Break
Take a break from to digital world – and that means every digital device you are exposed to. We live in environments and with objects that make us focus our attention for long periods of time. Bright lights beam into our eye constantly as we stare at our televisions, computers, tables and smartphones. We can be laser focused for hours as we lose track of time.
Step away to take a break from technology. It will do your physical and mental body good. More importantly, it will save you wear and tear on your eyes over time. Even looking away from the screen every few moments while you sit can help. Take a coffee break and go talk to your favorite office friend. Your eyes will thank you later and your social life just may improve.
Take Off Those Coke Bottles (or Contact Lenses)
People with mild vision challenges are often advised not to wear their glasses or contact all the time. It can create an unnecessary dependency. Eye muscles, like any other muscle in the body, can atrophy and weaken if they are not being used properly. It is important for you to train those muscles just as you would train the biceps in your arms.
Why not take off your glasses or contacts if you are in a safe, familiar environment such as your home or office? We know these places like the back of our hands. You could easily find the sofa, your bed and even items in your kitchen if you needed to without the use of your eye helpers. If you are able, give the crutches a break and build those muscles.
Look North South East and West
Our modern lives often only require us to look in one direction. As human we have tunnel vision and we look straight ahead most of the time. Rarely is there eminent danger that we have to be aware of as modern humans. As a result, our peripheral vision suffers. It is important to strengthen the vision you see out of the side of your eye. The following exercises will assist with improving the peripheral vision.
Sitting in a comfortable position with your eyes open, start by looking straight ahead. Look up as far as you can and hold for 30 seconds. Then look to your right as far as you can see. Hold this gaze for 30 seconds. Next look down and then to the left, holding each for 30 seconds. As you hold the gaze in each direction, purposefully try to see further than you normally would. Do not strain, simply try to see beyond your comfort zone. Go through the cycle two more times and then reverse. Repeat the same exercises, clockwise and counter-clockwise, with your eyes closed. After you are finished, rest with your eyes closed.
The Funky Four Corners
The next exercises are similar to the previous set, except you will start by looking up and to the right while you hold for 30 seconds. Then look down and to the right and hold. Repeat to the bottom left and then to the top left to complete the clockwise rotation, holding each for 30 seconds. Repeat the series two more times and then reverse. Finally repeat the same exercises, clockwise and counter-clockwise, with your eyes closed. After you are finished, rest with your eyes closed.
If you find that the exercises make you dizzy or uncomfortable, shorten the length of holding time and do not strain. Take your time, this is not a sprint. Natural healthcare is always a marathon. In the words of Mr. Miyagi from the Karate Kid, “Patience Young Grasshopper”. Practice and it will come.
Are you willing to take the test? Give these simple exercises a try. At worst, they will not work and you can go back to your coke bottle frames. At best, you will impress your optometrist and improve your vision for the long haul.
Are Colored Contact Lenses Safe?
Have you ever wished you had dazzling blue eyes, or have you ever admired the unique violet eyes of Elizabeth Taylor and wished you could have the same? You can’t do anything about the genetic hand you were dealt at birth, but you can easily change your eye color at any time you want without surgery. You just need colored contacts.
Colored contacts are tinted to change the color of your iris. An enhancement tint can deepen the intensity of your natural color. For example, if you have light blue eyes, you can make them a deep, dark blue.
What most people think of when they think of colored contacts are opaque tints. These are solid-colored lenses that can be used on dark eyes and that can change your eye literally any color. You can even get specialty lenses such as those that glow in the dark. Costume lenses and those used in the theater and film are opaque tints. These lenses are used in movies like Twilight with fantasy creatures like vampires and werewolves.
Opaque tints can inhibit your vision slightly because they remain fixed while your pupil may not. For example, your pupil gets larger in low-light situations, opening up your field of vision. However, the open area on the contact lens remains the same, so you may have some limited sight.
Color contacts can include vision correction, or they can be purchased simply for fashion. Plano color contacts are those that are worn for cosmetic purposes only.
Whether you are purchasing color contacts for vision correction or not, you must have a prescription for them. The FDA considers color contact lenses to be medical devices, and it is illegal to sell them without a prescription. However, that doesn’t stop people from selling them at flea markets, novelty shops and online.
Wearing colored contact lenses can be perfectly safe — if you buy them with a prescription from a reputable vendor and you follow the right care instructions.
To purchase colored contact lenses, you must visit an ophthalmologist for an eye exam and fitting. Contact lenses are designed to fit the individual wearer. If you put on contact lenses that are not designed for your eye, you risk damaging your eye and losing your eyesight. Your eye doctor will write you a prescription, which you can use to shop online or at an eyeglass shop.
Getting a prescription is the single most important thing you can do to safely wear contact lenses. Other care instructions include:
- Wash your hands before handling your contact lenses or putting them in your eye.
- Use a specially designed contact solution to clean your contacts. Never use water or saline and never reuse the solution.
- Never wear your contact lenses to sleep.
- Never wear your contact lenses while swimming or showering.
- Never share contacts with another person.
- Don’t wear contacts if your eyes are red or irritated.
- Always clean your contact lens case with the specially designed contact solution, and never transfer solution between cases.
- Keep the bottle of contact lens solution clean, and don’t allow the tip to become contaminated by touching it with your hand or other surfaces.
- Replace your contact lenses as recommended by your eye doctor and your case every three months.
These care instructions are designed to minimize the risk of infection. You can spread bacteria through your hands. Water can also spread bacteria and dry out your lenses.
Risks of infection or wearing contact lenses that don’t properly fit include:
- Scratches and abrasions on the cornea, which is the dome that covers your iris
- Ulcer on the cornea
- Infection
- Conjunctivitis (pink eye)
- Appearance of blood vessels in the cornea
- Vision problems
- Blindness
What may start as a seemingly minor symptom can lead to serious vision problems or loss very quickly. It is important that you see your eye doctor right away if you have any signs of redness, eye pain or vision problems.
You can safely enjoy the many benefits of wearing colored contacts so long as you follow the right care instructions and you see your eye doctor for a proper exam and fitting. You may pay a little extra for the exam, but you’ll pay far less in the long run for medical bills and the personal cost of pain and vision loss. If cost is a concern, you can also talk to your doctor about getting daily disposables, which are a suitable option if you only plan to wear the contacts on special occasions.
Dry Eyes: Who Gets This Condition and How To Treat It
As the name suggests, Dry Eyes is a condition where an individual does not have enough tears in the eye to nourish and lubricate it. This condition leaves the eyes dry, uncomfortable and with improper vision. The clarity of vision is highly dependent on the health of the front part of the eye, and tears play a major role in maintaining that health.
Glands around the eyes secrete tears, which consist of oils, water, mucus, special proteins, and antibodies. When an individual blinks, the eyelids spread tears across the cornea and provide the lubrication, reduce the risk of infection, clean up, and clear up the eye. Small drain ducts in the corneas drain excess tears to the back section of the nose.
If the tear system is not working properly, poor quality tears or lack of enough tears usually results in dry eyes. Someone with dry eyes will usually experience the following symptoms:
- Sensitivity to light
- Pain the eyes
- Itching eyes
- Reddening eyes
- Deteriorating vision
- Feeling of sand in the eyes
- Excess production of tears
Excess tear production resulting in tears running down an individual’s face might sound contradictory to the condition, but it is a case of lack of tear lubrication. The nervous system can respond to dryness by flooding the eye with tears, a situation that does not meet the lubricating need of the eye. The excess watery tears only wash the eye, but do not contain the normal tear composition that the eye requires.
Who gets Dry Eyes?
Dry eyes can result from several factors, all of which affect the proper functioning of the tear film. The following are people who will most likely develop dry eyes:
- People with eye correctional treatments
Lasik and other forms of eye surgeries can affect the proper functioning of the tear film. In addition, using contact lenses for many years can contribute to dry eyes.
- People over 65 years
The natural aging process brings about conditions that affect the normal functioning of the body. Many people over 65 years will start developing dry eyes symptoms. Medical attention can help to relieve the dry eyes and its effects.
- People in harsh environmental conditions
The environment has a role to play in contributing to dry eyes, and the worst conditions include smoke, dry climates, and winds. In addition, situations like staring at a computer that cause an individual not to blink for long periods can cause dry eyes.
- Pregnant women
Women have a higher tendency to developing dry eyes compared to men. The factors that contribute to dry eyes in women include hormonal changes, which are a result of pregnancy, menopause, and use of some contraceptives.
- People suffering from medical conditions
Medical conditions such as diabetes, inflamed eyelids, rheumatic arthritis, and thyroid complications will usually result in dry eyes. In addition, most eyes related conditions and turning of the eyelids would lead to dry eyes.
- People under medication
Some medication interferes with the production of tears, and people taking such medicines will experience dry eyes for as long as they are on that medication. Medication such as decongestants, antihistamines, antidepressants, and blood pressure medication lead to dry eyes.
Dry Eyes treatment
Although there is no cure for dry eyes today, an individual suffering from the condition can go for any of these treatment courses with consultation from an eye specialist:
1. Nutritional treatment
Adopting an omega-3 rich diet or taking fish oil can help people suffering from dry eyes to recover from the condition. Nutritional treatment is proving to be an effective and long-term form of treatment for this and other diseases.
2. Use tear drops
An individual can find a range of teardrops in his or her local pharmacy, and these can relieve the dry eyes effect. Although the different tear drops work differently on different people, it is important to get professional assistance with regard to the ones that will work for your eyes. These artificial tears play the role of normal tears, and help to keep eyes lubricated for the day.
3. Prescription eye drops
People suffering from chronic dry eyes can get prescription eye drops that can increase the eye’s ability to produce more tears. An example of these drugs is Restasis, which is FDA approved and offers relief from the effects of dry eyes.
4. Closing tear drains
The eyes have tear drains, which in some cases can drain the eyes sooner than the tears have played their part. An individual in such a situation can therefore have his or her tear drain plugged temporarily or permanently, and give the tears an opportunity to play their part.
