Sunglasses, UV and your eyes.

Protecting your eyes from UV.


What is UV?

Ultraviolet (UV) radiation is a type of electromagnetic radiation, which is the part of the energy the earth receives from the sun. It is invisible so we cannot feel or see it. Sunlight is essential to us as it is nature's best source of Vitamin D and dopamine.


There are three types of UV: A, B and C.

UV C is the strongest and most harmful but the ozone layer prevents UV C from reaching us. The easiest way to explain UV A and UV B is this: UV A is UV Aging rays and UV B is UV Burning rays. UV B is shorter wavelength which is more damaging as it causes sunburns and increases risk of developing skin cancer. Harmful UV radiation does not necessarily refer only to that directly from the sun but also includes that reflected off surfaces such as water, windows, roads and snow.


UV in QLD

We are living in Australia, in QLD, the Sunshine State!

UV radiation is measured in a unit called the UV index, which was created by the World Health Organisation. The range is from 0, the lowest, to 11+ extreme. Protection against sun is recommended when the UV index is 3 or higher.

UV Related Eye Conditions

Too much sunlight is never good for you as it can damage your eyes. It is important to note that it is not just adults who work outside, but also children who are at risk of excessive UV exposure and the associated adverse effects. Excessive exposure to UV causes:

Eyelids - wrinkles, sunburn and cancer, just as can occur elsewhere on the body

Ocular Surface - abnormal growths such as pterygium and pinguecula. Pterygium is a condition in which an opaque tissue grows on the ocular surface and may extend to and over the cornea, the translucent window of the eye, and can impair your vision. A Pterygium can only be treated by surgery.

Cornea - snow blindness, welders flash. UV can damage your eyes even in winter with increased reflections from the snow. It commonly appears in skiers when they don't wear goggles. It is also known as sunburned eye or sunburned cornea. This is a painful condition which causes a temporary loss of vision.

Lens – Cataract. Cataract is an opacification of the clear crystalline lens due to clumps of broken proteins inside the lens. This condition can be age-related, disease-related (such as diabetes), traumatic or from some medications. Long-time UV exposure significantly increases the likelihood of developing cataracts.

Retina - the back of the eye. Most UV is absorbed by structures in the front part of the eye but some still can penetrate through the eye to reach to the retinal surface. The retina may be damaged seriously with UV B. Macular degeneration and retinal melanoma (cancer) are examples of conditions that can be caused by UV B exposure.


UV protection with spectacles: Sunglasses and Transition lenses

UVProtection

Wearing sunglasses is necessary to protect your eyes and the surrounding structures of the eyes. The importance of wearing sunglasses for eye health, especially for children, outdoor workers, and sports players, must be emphasised.

The best sunglasses for you should fit well on your face and close to your eyes. Wrap around style sunglasses are best for reducing UV from radiations entering from the sides of the lenses. Polarised sunglasses are another beneficial option to improve your UV protection and vision. Regular, non-polarised, lenses can protect eyes from UV radiation directly from the sun, however are limited in blocking the reflected rays off surfaces such as water, windows, roads and snow. Polarised lenses will reduce the intensity of glare and reflected light and will improve the clarity of your vision. They work by blocking light rays polarised in a particular orientation and will reduce up to 50% of reflected rays.

Finding Relief From Eye Allergies

Added on 21 May 2013 by Stuart Macfarlane

People who have allergies are often quick to seek help for symptoms like sneezing, sniffling, and nasal congestion. But allergies can affect the eyes, too, causing red, itchy, burning, and watery eyes and swollen eyelids. The good news is that the same treatments and self-help strategies that ease nasal allergy symptoms work for eye allergies, too.

Eye allergies, also called ocular allergies or allergic conjunctivitis, affect one in five Americans. Though the symptoms they cause can be annoying -- not to mention unbecoming -- they pose little threat to eyesight other than temporary blurriness. But red, itchy, burning, and puffy eyes can be caused also by infections and other conditions that do threaten eyesight. So, it's smart to see your doctor if eye symptoms don't get better with self-help strategies or over-the-counter allergy remedies.

Like all allergies, eye allergies are caused by a glitch in the body's immune system. The trouble starts when the conjunctiva (the mucous membrane that lines the eyelids and covers the whites of the eyes) comes into contact with something that, while actually harmless, is seen as a threat. In a mistaken attempt to fight off the threat, the immune system makes antibodies that cause your eyes to release histamine and other substances. That, in turn, makes eyes red, itchy, and watery. Eye allergy symptoms can happen alone or along with nasal allergy symptoms.

Allergies: Seasonal and Perennial

There are two types of eye allergies: the more commonly found seasonal allergies, and perennial allergies.

Seasonal allergies happen only at certain times of the year - usually early spring through summer and into autumn. They're caused by exposure to allergens in the air, commonly pollen from grasses, trees, and weeds, as well as spores from molds.

Perennial allergies occur throughout the year. They're caused mostly by exposure to dust mites, feathers (as in bedding) and animal (pet) dander. Other substances, including perfumes, smoke, chlorine, air pollution, cosmetics, and certain medicines, can also play a role.

Sometimes, its easy to tell whats causing an allergy -- for example, if symptoms strike when you go outside on a windy, high-pollen-count day, or when a furry friend climbs onto your lap. If its not clear just what you're allergic to, a doctor can give you a simple test to find out.


The first approach to controlling eye allergies should be to limit your exposure to allergy triggers:

  • Stay indoors when pollen counts are highest, usually in mid-morning and early evening. Close the windows and run the air conditioner (window fans can draw in pollen and mold spores). If you go out, wearing eyeglasses or big sunglasses can help block pollen from your eyes. Driving? Keep the windows closed and run the air conditioner.
  • Limit your exposure to dust mites by encasing your pillows in allergen-impermeable covers. Wash bedding frequently in water thats at least 130 F. If your mattress is more than a few years old, consider getting a new one. Old mattresses are often teeming with allergens.
  • Clean floors with a damp mop. Sweeping tends to stir up rather than get rid of allergens. Especially if a pet shares the house with you, consider replacing rugs and carpets, which trap and hold allergens, with hardwood, tile, or other flooring materials that are easier to clean. Go with blinds instead of curtains.
  • To stop mold from growing inside your home, keep the humidity under 50%. That might mean using a dehumidifier, especially in a damp basement. If so, clean the dehumidifier regularly. Clean your kitchen and bathrooms with a bleach solution.
  • If your pet is causing your allergies, try to keep it outside as much as possible. At the very least, keep it out of your bedroom. Don't let it share your bed.
  • Don't rub your eyes. Thats likely to make symptoms worse. Try cool compresses instead.

Allergy Medications for Eyes

What if avoiding allergy triggers isn't enough to relieve eye allergy symptoms? Over-the-counter and prescription medications can provide short-term relief of some eye allergy symptoms, while prescription treatments can provide both short- and long-term help. Remedies include:

  • Sterile saline rinses and eye lubricants can soothe irritated eyes and help flush out allergens.
  • Decongestant eye drops can curb eye redness by constricting blood vessels in the eyes. But these drops tend to sting a bit, and they don't relieve all symptoms. Whats more, their effect tends to be short-lived, and using them for more than a few days can cause ''rebound'' eye redness.
  • Eye drops containing ketotifen can relieve allergy symptoms for up to 12 hours. They wont cause rebound redness even with long-term use.
  • Refrigerating eye drops may help them provide additional relief of allergy symptoms.
  • Oral antihistamines can also help. Loratadine (Claritin) and cetirizine (Zyrtec) tend to be less sedating than some older drugs, and they provide longer-lasting relief.

If these drugs aren't enough to do the trick, a doctor can prescribe other eye drops, including combination antihistamine-mast cell stabilizers and corticosteroids. If allergies are especially severe or persistent, allergy shots (immunotherapy) can also help.


9 Signs that you need an eye exam

Added on 16 May 2013 by Stuart Macfarlane

When should you get an eye exam? Everyone is not the same so it is important to follow the advice your eye care provider recommends. If you are unsure because you have not been to the eye doctor in a long time, here are seven signs that should send you to the eye doctor for an eye exam.

Unlike going to the dentist, its generally not necessary to see the eye doctor every 6 months for an eye exam.

Typically, a comprehensive eye exam every 2 years will ensure that your eyes stay healthy and your vision remains sharp. If you have a medical condition like diabetes or other ocular disorders, previous eye trauma or surgery, high prescriptions, a lazy eye, or a family history of glaucoma or macular degeneration, you will need to have more frequent eye exams.

However, there are some signs and symptoms that should send you to the eye doctor for an eye exam even if you arent due up for one. If you experience any of the nine symptoms below, you should schedule an eye exam as soon as possible, and in some cases, immediate medical attention is required.

1. Sudden Blurry Vision or Problems Focusing

Sudden blurry vision or focus problems can be a sign of a larger health issue and should always be taken seriously. If the blurry vision comes and goes, or is limited to one eye, you should schedule an exam with an optometrist or ophthalmologist as soon as possible.

2. Sudden appearance of visual disturbances such as floaters, flashes of light, or obstruction of vision

Sudden onset of any of these visual disturbances could be a sign of a serious, vision-threatening disorder such as a retinal detachment, retinal tear, or retinal hole. Anyone who experiences these signs must seek immediate (within 24 hours, or sooner) medical attention by an optometrist, ophthalmologist or emergency room physician for proper diagnosis and treatment to minimize vision loss.

3. Gradual Blurring of Vision

This is the type of vision degradation that gradually happens over time. If you are noticing that youre moving a book or the computer screen further away from your eyes than you use to to improve clarity, its probably time to get an eye exam. Same goes if you notice yourself sitting closer to the television or bring objects closer to you to read them (like a cereal box, for instance.)

4. Headaches

Frequent headaches can be a sign of a vision problem. Changes in vision take place slowly and are often imperceptible to the patient at first. However, headaches can be one of the early warning signs of a change in vision. If you are experiencing re-occurring headaches, you may want to consider getting your eyes checked.

5. Eye Pain or Eye Fatigue/Strain

Having some infrequent eye pain or eye strain isnt usually a big problem. Everything from the amount of sleep your getting to seasonal allergies, or the cold or flu can cause temporary eye pain or fatigue. However, if you experience ongoing eye pain for more than a few days, or if you experience ongoing eye pain with eye movements, its a good idea to get it checked out. It can sometimes be a sign of an eye infection or more serious health condition, or even a warning sign that your vision has changed. Get it checked out.

6. Squinting

Frequent squinting is the quintessential sign that its probably time for an eye exam. We squint when were having difficulties seeing because the act of squinting reduces extraneous light entering the eye and reduces light scattering, improving vision. This is often one of the first signs in children that they may need eyeglasses. In addition, squinting coupled with an eye turn, more commonly called a "lazy eye, is a definite red flag that a comprehensive vision exam is in order. This is especially true in children, and if not detected and treated early enough, permanent vision loss may result. If you notice yourself squinting more than usual, schedule an eye exam.

7. Sensitivity to Light

A sudden onset of sensitivity to light can be a sign that you should get an eye exam. Light sensitivity can be a symptom of a number of disorders or eye diseases (as well as an eye infection.) So if you find yourself regularly experiencing light sensitivity, get an eye exam.

8. An Eye Infection

If you experience swelling of the eyelids, itchiness, redness, a pink discoloration of the whites of your eyes, and/or discharge, you may have an eye infection. If you experience any of these symptoms, schedule an eye exam immediately to have it looked at.

9. One Bonus: If You Havent Had an Eye Exam in the Past Two Years

If you havent had a full eye exam in the past two years, you should schedule one especially if you are over the age of 40. It is important to note that for some people, an exam sooner than every two years is critical to ensuring your eyes stay healthy.

Natural changes in the eyes associated with age makes more frequent eye exams necessary as you grow older, especially if you havent had one in a few years.

Even if you are between the ages of 20 and 40, an eye exam is an important part of maintaining your vision and overall health. Eye exams can often reveal developing health issues that arent easily found even with a physical by a family doctor. Children may require eye exams every year or sooner, as their vision changes rapidly with growth. So get those peepers checked and please remember to follow your eye doctors recommendations for follow-up visits and annual exams!

Diabetes and your vision. What you need to know.

Added on 23 April 2013 by Stuart Macfarlane

Unfortunately, patients with diabetes are at risk for a great deal more eye issues and infections than the average person. In fact, people with diabetes have a higher risk for blindness and related issues than do other people with other issues around and surrounding the eye. Nevertheless, with regular checkups, there are ways for even diabetic patients to ensure that they will get the most out of their eye health and their life, and ensure that their vision is taken care of adequately by their optometrist. Here are just a few important things you can do to ensure that your vision stays healthy and up to date, and that if you do have diabetes, you get the most out of your visits to the optometrist and your work in improving your overall eye health.

Get Regular Eye Exams and Check Ups!

Diabetic patients need to get annual eye exams and checkups by their optometrist, no matter what. Whether you are experiencing problems with your symptoms or not, it is important to find an optometrist who can adequately treat diabetic patients and more. This will allow your optometrist to know and understand your level of diabetic retinopathy, and will create for you the perfect management of your vision and overall eyecare.

Work with a doctor to control your blood sugar levels

This can be extremely important for diabetic patients, but you must understand that it is critical to work with a doctor to control blood sugar levels. By doing this you greatly lower your risk of having eye problems, and you make it so that you, as a patient, does not have to go through some of the more serious issues related to your condition, and diabetes in general. In turn, too, you can better manage and control eye-related problems and issues over time, so that you need not worry about diabetes flare-ups or worse.


Keep the rest of your body healthy during your diabetes

Whether it’s maintaining a healthy blood pressure, or making sure that you quit smoking, it is absolutely essential that you keep your body healthy regarding the diabetes issues, especially as they relate to your vision. This means working so that you perfect and maintain your body to get to the point where you need not worry about major flare-ups, and other medical problems related to the diabetes itself and the overall health of your body and eyes more generally.


All in all, it’s absolutely critical for you to ensure your good health by managing your diabetes well, while still getting the most out of your vision and your eye experience working closely with your doctor. For those who are able to adequately and safely do that, they can expect a great deal of solid health and long-term eye care and management thanks to their proactive habits of taking care of their eyes, which is no small task in a patient with diabetes.
