8 THINGS YOU SHOULD KNOW ABOUT BLUE LIGHT AND YOUR EYES
There is no escape from using screens in today’s world. Whether phones, tablets, or computers, everyone’s eyes are glued to a device at least part of the day. These screens emit blue light…a frequency of the light spectrum that is all around us: sun, digital devices, LED light bulbs. Blue light wavelengths are shorter than other types of light. The shorter the ray, the higher the energy beaming into our eyes. Blue light is the part of the spectrum that has the most energy of any visible light.
Should we, and how do we, protect our vision from negative effects of this intense light? Here are 8 pieces of information that will help you to understand and respond to the increased presence of blue light in our lives.
1) Can cause damage. It is well known that UV rays (invisible) can cause sunburns and harm eyes. The more visible blue light ray have similar energy to sun UV rays and can also cause visual damage.
2) Serves a good purpose. Blue light has its benefits: it regulates hormones that balance our 24 hour circadian rhythm Seasonal affective disorder is treated with white lights containing amounts of blue light.
3) Deeply absorbed into eyes. The difficulty caused by blue light is that our eyes are not adept at blocking blue light rays. The eyes absorb blue light more deeply than the sun’s UV rays. Blue light can pass beyond the cornea and lens into the more sensitive retina and can trigger detrimental changes.
4) Causes eye strain. Blue light wave lengths make contrast more difficult to see, resulting in increased eye strain when using computers, phones, etc. As a result our eyes become sore and red.
5) Difficult to sleep. Late in the day exposure to blue light can interfere with our sleep patterns. It is a good idea to use blue light filters on any screens at night.
6) Long term damage. Over a period of time, recent studies have indicated that blue light could lead to macular degeneration.
7) A concern for children and adults. Blue light damage is not age specific. Though damage from continuous exposure is more likely to show up at an older age, it is important to remember that our children and teens are staring at screens for most of the day.
8) See your eye doctor for many options. Computer glasses prescribed by your doctor can help reduce exposure to blue light in both prescription and non-prescription glasses. Some eyeglass lens companies have anti-reflective coatings that block blue light from digital and natural sources. Photochromic lenses also protect your eyes from indoor and outdoor sources by getting darker or lighter as needed automatically. Check with your vision care specialist for all the options available.
Our office provides a number of lens choices to protect your eyes from blue light. Make an appointment and our team can help you select the best option for your needs!
FIVE THINGS TO KNOW ABOUT EYE ALLERGIES
Eye allergies can be seasonal or present all year. Also known as allergic conjunctivitis, it is your eyes’ response to allergens… such as pet dander, dustmites, pollen, mold. Some medications and makeup can cause eye allergy signs and symptoms. Following are 5 things for you to know if you ever experience ocular allergies.
1) The main signs of eye allergies are red, itchy, tearing or swollen eyes. Sneezing, coughing, and fatigue may also be present. Some patients report blurry vision, especially upon awakening.
2) If you are allergic to airborne irritants such as pollen it is best to stay inside on windy days. If you must be out, use a pollen mask when doing yard work, or when cleaning dusty areas in the house. Sunglasses or your regular glasses can help protect the eyes from pollen, dust, etc.
3) Medications can help relieve your symptoms. Steroid nasal sprays and oral antihistamines can help with general allergic reaction including your eyes. Ask your doctor about eye drops. Not all eye drops are created equal!
4) Wash your bed linens and pillows in hot water often…and consider allergen barrier covers for mattress and pillows.
5) Limit your contact lens wearing time or eliminate the lenses when your ocular allergies are flaring up. Know how to manage your allergies so that you can still enjoy doing the things you like!
QUESTIONS ABOUT EYES
1) What exactly are cataracts, and what are the symptoms if cataracts are developing in my eyes?
ANSWER:When the normally clear lens within your eye becomes cloudy or opaque, it is called a cataract.IT IS NOT A FILM THAT GROWS OVER THE SURFACE OF THE EYE, as some people mistakingly think.
Cataracts most often develop in persons over the age of 55, but they are occasionally found in younger people, including newborns. A cataract in a newborn is called a congenital cataract. Besides the normal aging of the lens inside the eye, cataracts may develop from certain medications, some systemic diseases, or from eye trauma or injury. Excessive exposure to UV radiation present in sunlight, cigarette smoking, and a poor diet can all contribute to cataract development.
Some common symptoms that people may experience are: Increased haziness causing blurred or distorted vision…Increased sensitivity to glare from lights,especially when driving at night…An increased need for more light to see clearly…A gradual loss of intensity of color vision
2)What exactly is dry eye, and what are the symptoms of dry eye? How is dry eye treated?
ANSWER: Dry eye is the term used to describe eyes that either do not produce enough tears for proper eye lubrication, or the tears that are produced are deficient in their chemical composition, so as to not provide adequate protection to sensitive eye tissue.
Some of the chief causes of dry are: THE NORMAL AGING PROCESS…PROBLEMS WITH NORMAL BLINKING…CERTAIN MEDICATIONS LIKE ANTIHISTAMINES, ORAL CONTRACEPTIVES, AND ANTIDEPRESSANTS…ENVIRONMENTAL FACTORS SUCH AS DRY CLIMATE OR EXPOSURE TO WIND…GENERAL HEALTH PROBLEMS LIKE ARTHRITIS OR SJOGREN’S SYNDROME…CHEMICAL OR THERMAL BURNS TO THE EYE.
The symptoms of dry eye include: Irritated. scratchy, uncomfortable eyes…eye redness…a burning sensation…a feeling of a foreign body in the eye…excessive watering as the eye tries to produce more tears. Treatments include:
CHANGING ENVIRONMENTAL FACTORS LIKE AVOIDING WIND AND DUST AND INCREASING THE LEVEL OF HUMIDITY, USING OVER THE COUNTER ARTIFICIAL TEAR SOLUTIONS AS RECOMMENDED BY YOUR OPTOMETRIST, USING MOISTURIZING OINTMENT AT BEDTIME, USING R.X. EYEDROPS PRESCRIBED BY YOUR OPTOMETRIST IN MORE SEVERE CASES, INSERTION OF SMALL PLUGS (PUNCTAL PLUGS) IN THE TEAR DUCTS.
Don’t hesitate to discuss concerns about any of these conditions with your optometrist. It pays to be pro-active in all areas of your health.
1) When should I first have my child’s eyes examined, and is the school eye check enough to ensure that my child’s eyes are ok?
ANSWER: I always tell parents that there is really no specific time to start children’s eye exams, and that I will see them at ANY age if the parent notices anything suspicious, such as:
-red or swollen eyes or eyelids,
-an eye that turns inward or outward
-excessive eye rubbing or squinting
-discharge from the eye
Fortunately, eye problems in infants and toddlers and pre-schoolers are not that common, so I highly suggest that the child’s first eye exam (barring any of the above-mentioned conditions) be at around age 5, and certainly no later than age 7, when reading and writing skills come into play.
As to the second part of the question concerning school eye screenings, there is really no comparison to a full eye examination. A vision evaluation in my office always includes tests for eye alignment, color vision perception, depth perception, eye movement control, precise visual acuity at both distance
and reading, and eye health assessment. Thorough consultation with the parent concerning recommendations and treatment protocols is also a vital part of the examination.
The schools certainly do not have the time or professional expertise to do all of these testing protocols, so you should make sure that your child receives a professional eye exam no later than age 7.
2. Are contact lenses safe, and at what age should I consider contact lenses as an option for my child?
ANSWER: Today’s contact lens technology indeed insures that properly fitted contact lenses are a safe option for vision correction. Professional contact lens fitting
– complete eye-health evaluation
– complete medical and ocular history
– thorough refraction of the eyes
– precise measurement of the eye’s curvature
– trial in-office fitting to show the patient the comfort and vision to be expected
To be more specific, you should be professionally fitted and monitored by an experienced practitioner who is willing to spent the necessary amount of time with you. It is your eye doctor’s clinical skills that will assure you that your eye health is not compromised, and the contact lenses are providing maximum visual acuity without any undo discomfort. I personally prefer to wait until the child (patient) is in middle school before considering contact lenses (at least age 12).
It is not too early to be thinking about preparation for back to school time. Make sure to include your child’s vision examination as part of the process.

HIGH BLOOD PRESSURE
Nearly 1 in 3 adults has high blood pressure or hypertension reports the American Heart Association. To understand the relation of hypertension and our eyes: Every heartbeat causes blood to put pressure on the arteries and capillaries that carry it. High blood pressure is when your heartbeat exerts too much pressure on the vessels. Hypertension that goes on for an extended time can damage the vessels which in turn will cause harm to the organs they supply.
…including the eyes.
High blood pressure can even hamper your vision by causing swelling in the optic nerve. It also causes small hemorrhages and narrowing of the eyes’ blood vessels. Other eye related issues related to high blood pressure are: optic neuropathy (damage of the optic nerve caused by a blockage of its blood supply), choroidopathy(fluid build up under the retina), and hypertensive retinopathy (retinal vascular damage).
2) Symptoms of eye damage caused by high blood pressure can vary…such as impaired vision, double vision, headaches, blind spots, burst blood vessels. Often these symptoms do not manifest till much damage has already occurred.
3) Risk Factors include
-high blood pressure over a long period
-hardening of the arteries
The main therapy is to keep high blood pressure under control through medications and life style changes.Taking steps to reduce the above risk factors is vital.
High blood pressure can damage your eyes as well as other organs of your body. Let your health care practitioners, including your optometrist, know of any family history of high blood pressure, stroke, cardiac disease. Have your pressure checked on a regular basis and follow guidelines for healthy living.

4 TIPS FOR BACK TO SCHOOL EYE HEALTH
Does it seem like summer is flying as quickly as usual? It is time to start planning for the fall and back to school eye exams are high on the agenda for families.
1) EYE EXAM SAVVY
—Know the difference between vision screenings and a comprehensive eye exam.
—Often schools will perform periodic visual screenings. While many children have been helped by these beneficial screenings, some vision difficulties can go completely unnoticed. Vision conditions which are imperceptible during a screening can interfere with the child’s academic achievement and athletics participation.
A complete eye exam evaluates such areas as
-visual function such as depth perception,
peripheral vision and color vision
-eye focusing and movement ability
-family eye health history
All are vision aspects vital for a child’s development. A vision screening is no substitute for an eye health exam.
2) SCREEN HYGIENE
We are all spending a larger part of our day staring at screens. The Huffington Post reports that more leisure time is now spent on digital devices than watching television. With visual systems still developing, vision coordination/organization demands on children are even more exacting than upon adults. Some rules of thumb to follow:
-20/20/20 rule- every 20 minutes focus on an object 20 feet away for 20 seconds
–consider computer glasses for more accurate acuity and for protection from blue light damage to the eyes
–Encourage and enforce “screen vacations..”
a day or afternoon without any screen time.
3) HYGIENE- Protect from illness
Your eyes are not only the window to your soul but also a portal to illness. Specific eye diseases such as conjunctivitis (pink eye), viruses like the flu or a common cold, can invade your body via your eyes.
-don’t share personal items-makeup, towels
-never share “costume” or any other contact lenses
-avoid touching or rubbing your eyes
4) SPORTS VISION PROTECTION
Between the ages of 11-14 most children’s eye injuries occur when playing sports without the appropriate protection.
–The National Eye Institute reports nearly 35,000 eye accidents a year. Articles by The Vision
Council state that eye injuries are the leading cause of blindness in children.
– Options for protective eyewear include: general sport goggles, helmet goggles, and swimming goggles. Our office carries Rec-Specs which can be ordered with or without prescriptions and tints.
Before your children pack school supplies in their backpacks and get on the school bus, make sure that their eyes are ready for a great school year in the classroom and on the playing fields.
8 EYE SYMPTOMS NOT TO IGNORE
Regular eye exams are a vital component of vision health, but can also impact a person’s general health.Symptoms that are potentially serious can go undetected without a comprehensive eye exam. Eye exams are not only about getting glasses or contactsbut also about attending to any emerging conditions dealing with vision loss.
A study published in the American Academy of Optometry journal Optometry and Vision Science indicates that over 100 million people in the world have correctable vision deficits. It is estimated that only half of the 61 million people who are at high risk for vision loss had an eye exam in the last year.
1) Sudden eyelid droop
A sudden droop in one of your eyes could point to an aneurysm or a bulging weak area in an artery in your brain. They aren’t always dangerous but when they rupture, they can cause brain damage or death.If pupils are unequal in size, the indication for an aneurysm is even stronger.
Anyone experiencing these symptoms should immediately go to an emergency room.
2) Eyeball pain
Sudden pain in your eye, without any apparent injury, could be due to glaucoma with building eye pressure.Other possible reasons include eye inflammation or dry eyes.
Glaucoma is a disease involving optic nerve damage. Eye pressure plays a role in damaging the delicate nerves. When a large number of nerve fibers are impaired, blind spots occur. Eye pain could be an early sign of glaucoma.
If you experience severe pain, make an emergency visit to your eye doctor within 24 hours.
3) Hazy, blurred vision in your visual field
This symptom could be related to a clot that is that is obstructing circulation in the brain, optic nerve, or retina.It could indicate that the person is having a stroke or be at risk for an imminent stroke. Retinal detachment is another possible cause of this symptom.
Go to an emergency room, even if the symptom is transient.
4) Sudden increase in floaters or flashing lights
Floaters are very common for many people…spots that drift and are even more pronounce is certain lighting. Infrequent floaters are not dangerous, but a sudden increase of floaters or flashing lights can mean a retinal tear or detachment requiring immediate surgery. A tear or detachment occurs when the the vitreous pulls away from the retina. Anyone can experience a retinal tear or detachment, but risk factors include age, near sightedness, recent cataract surgery, and trauma.
See your eye doctor immediately within 24 hours.
5) Eye redness
Everyone occasionally has redness in their eyes.Common causes are allergy or acute injury or pink eye. With pink eye, over the counter drops can actually make the condition worse. Early detection and treatment help to halt the contagion.
Infrequent redness in the eyes is not necessarily a concern.However if it occurs more often and is
present with swelling, itching, and soreness, the patient should make an appointment to see the
eye doctor immediately.
6) Foreign object in eye
Foreign objects in the eyes can cause different degrees of pain from scratchy and annoying to
excruciatingly painful. If you are unable to flush out the object with clean water or saline, get
medical assistance promptly. Do not rub or try to remove the object yourself.
7) Discharge from the eye/crusty eye
If you notice a change in the color or consistency of your eye discharge, it could suggest that you have an eye infection. With pink eye, there is usually a thick green or yellow discharge.
8) Blurry vision, especially in one eye
You might chalk up blurry vision to fatigue or even illness, but this can actually be a sign of a variety of serious eye problems, from glaucoma to torn retina to AMD. If you’re experiencing blurry vision, get it checked out. And if the blurred vision is only in one eye, have it checked immediately.
Blurry vision can be a sign of serious eye conditions including a torn retina, Age-Related Macular Degeneration, and glaucoma. Have your eyes checked, and if the blurriness is in only one eye, have it immediately checked as a potential emergency.
You only have one pair of eyes…it is important to take good care of them. Better to be overly cautious with a minor issue than insufficiently attentive to a serious condition. Do not ever hesitate to call your eye doctor with concerns about your eye health. And schedule your regular eye exam as recommended by your doctor.
