Conjunctivitis is spread through contact with the eye drainage, which contains the virus or bacteria that caused the pinkeye. Touching an infected eye leaves drainage on your hand. If you touch your other eye or an object when you have drainage on your hand, the virus or bacteria can be spread.
Orthokeratology is a process that uses specially designed GP contact lenses to temporarily reshape the contour of the cornea to reduce myopia (nearsightedness). Orthokeratology is nicknamed "ortho-k" and sometimes called corneal reshaping (CR), corneal refractive therapy or vision shaping. Some new ortho-k lens designs are also available for farsightedness and presbyopia. Research has also demonstrated that orthokeratology lens designs slow the progression of myopia. Good candidates for orthokeratology include youngsters age 8 to 12 with progressive myopia, as well as most adolescents and adults, although the best success is with people under age 40. Ortho-k is recommended for low to mild nearsightedness (-4 diopters or less). People who are not good candidates include those with dry eye syndrome, a large pupil size, or high myopia.
Double vision, or diplopia, is a symptom to take seriously. Some causes of diplopia are relatively minor, but others need urgent medical attention. Take a look at the causes, symptoms, and treatments of double vision.
When one eye develops good vision while the other does not, the eye with the poorer vision is called amblyopic. Usually, only one eye is affected by amblyopia, but it is possible for both eyes to be "lazy." This condition is called bilateral amblyopia. The condition is common; approximately two or three out of every 100 people has amblyopia. The best time to correct amblyopia is during infancy or early childhood.
Nearsightedness can be easily diagnosed using standard eye exams given by an eye doctor.
Orthographically lens(Ortho-k)are lens to put in at night, and you can see the following day without glasses or contacts! They are rigid, and harder to put in, but here are the steps to do it.
New technology / new Ortho-k designs. A procedure that once took weeks (even months) to achieve now may be accomplished in a very short time (one to twenty days.)
The goal is to reduce Myopia and improve vision for the life-style choice of your patient. Enhanced vision provides freedom and confidence for daily activity. Functional vision without lenses is impossible without surgery or reshaping lenses.
Correcting astigmatism with contact lens requires a lens, that has a double prescription, to sit in a stable position. Small rotations of the lens cause blurring and occurs when the eyes move or blink. There is a multitude of stabilising methods that are employed to correct this but in combination with the tendency for the lens to dehydrate between blinks, then some wearers find their vision is annoyingly unstable.
Myopia, or “nearsightedness,” has always been a disadvantage for people. Whether it is eyeglasses or contact lenses, it is such a nuisance trying to have corrected vision each day. Forgetting to bring glasses when going to school, worrying about losing a contact lens when playing soccer, it’s such a hassle! It’s unclear what the actual cause of myopia is, but it seems that genetics plays an important role. We can’t really prevent ourselves from getting glasses; you either need them or you don’t. Although some adults choose to have laser eye surgery (LASIK), the results are mixed and usually entail a whole list of side effects depending on the individual. And of course, LASIK is not suitable for children and teens.
Specks in the Eye
Studies have indicated that Orthokeratology lenses may be a viable myopia treatment option to slow the progression of nearsightedness in children.
To investigate if the combination of partial reduction (PR) orthokeratology (ortho-k) and spectacles for residual refractive errors in the daytime was effective to slow myopia progression in high myopic children.
Your cleaning kit should contain (1) a cleaning solution (2) a soaking/rinsing solution (3) a clean storage case and possibly (4) eye drops for rewetting the devices while in the eye (Natural Ophthalmics Ortho-k Thick drops).
It is the Holiday Season and that means parties and fireworks will be taking up most of America’s time. But a new study shows that flying debris from the explosion of your firework may be more dangerous to the eye, than the power of the explosion itself.
Glaucoma is a group of eye diseases causing optic nerve damage. The optic nerve carries images from the retina, which is the specialized light sensing tissue, to the brain so we can see. In glaucoma, eye pressure plays a role in damaging the delicate nerve fibers of the optic nerve.
The old saying goes that watching too much TV will make your eyes go square. Nowadays, we seem to spend most of our time looking at screens: be it a computer screen at work, a mobile phone screen to make a call or a TV screen to relax. But how bad is looking at screens for our eyes? Is there really any truth behind the old saying?
As medical science has progressed, it has busted quite a few myths we have about different parts of the body. Sadly, some of them still linger. Dr Vandana Jain, a Cornea and External Diseases Specialist and the Co-founder and Director of the Advanced Eye Hospital busts some common myths about the human eye:
With more number of hours spent in the bright sun, our eyes along with the skin is also exposed to excessive UV radiations which can cause dryness, pinguecula (a disease where the conjunctiva of the eye degenerates with time), and even precancerous conditions of the ocular surface.
There's no substitute for the quality of life good vision offers. Adding certain nutrients to your daily diet, either through foods or supplements,can help preserve your vision. Researchers have linked eye-friendly nutrients, such as lutein and zeaxanthin, vitamin C, vitamin E and zinc, to reducing the risk of certain eye diseases.
Orthokeratology is a non-surgical treatment that uses precise, specially shaped contact lenses to temporarily reshape the cornea in order to eliminate nearsightedness or myopia so that you can see better at distance without wearing eyeglasses or regular contact lenses throughout the day.
Wear sunglasses whenever you are outdoors, whether you are working, driving, participating in sports, taking a walk, running errands or doing anything in the sun.
The sun supports life on our planet, but its life-giving rays also pose dangers. The sun's primary danger is in the form of ultraviolet (UV) radiation. Artificial sources, like welding machines, tanning beds and lasers, can also produce UV radiation.
Vision is much more than just seeing clearly. Many interrelated vision skills affect how well you play your sport. Just as exercise and practice can increase your speed and strength, they can also improve your visual fitness and accuracy.
The cornea is the clear front surface of the eye that bends (or refracts) light rays as they enter the eye. For clear vision, the cornea must have the correct shape and power to focus incoming light rays precisely on the retina at the back of the eye.
Eye exams for children are extremely important. Experts say 5 percent-10 percent of pre-schoolers and 25 percent of school-aged children have vision problems. Early identification of a child's vision problem is crucial because, if left untreated, some childhood vision problems can cause permanent vision loss.
Decorative contact lenses can change a person's eye color or create the effect of a character like a cat, zombie or vampire as part of a costume. However, buying these lenses without a prescription from an eye doctor can lead to serious health issues and potentially (and permanently) damage your eyesight.
You can wear contacts and cosmetics safely and comfortably together by following these helpful tips:
If contact lenses are right for you, your optometrist will provide you with the lenses, lens care kits, individual instructions for wear and care, and unlimited follow-up visits over a specified time. Hygiene is the most critical aspect of successful long-term contact lens wear.
Caring for your vision doesn't begin and end with eyeglasses, contact lenses and corneal modification surgeries like LASIK. There are many other things you can do to maximize and protect the vision you currently have.
Amblyopia is a childhood problem that happens when one eye is weaker than the other. The brain chooses to take in images from the stronger eye and ignore images from the weaker eye. This means that your child uses the strong eye more than the weak eye. If the weak eye doesn't have to work, it isn't able to develop good vision. This leads to poor vision in the weaker eye.
Many things and/or events can cause a strabismus. They include genetics, inappropriate development of the "fusion center" of the brain,
Sunglasses are a great and inexpensive way to protect your eyes from the sun.
Keratoconus treatment often depends on the severity of the keratoconus symptoms. During early stages, vision can be corrected with eyeglasses. As the condition progresses, rigid contacts may need to be worn so that light entering the eye is refracted evenly and vision is not distorted. You should also refrain from rubbing your eyes, as this can aggravate the thin corneal tissue and make symptoms worse.
Your ophthalmologist will be able to diagnose keratoconus during a routine eye exam. A slit lamp can be used to diagnose severe cases of keratoconus, but sometimes corneal topography is needed to diagnose the more subtle cases of keratoconus.
Keratoconus usually affects both eyes, though symptoms in each eye may differ. Symptoms usually start to occur in people who are in their late teens and early 20s and may include:
Keratoconus is an uncommon condition in which the normally round, dome-like cornea (the clear front window of the eye) becomes thin and develops a cone-like bulge. Keratoconus literally means “cone-shaped cornea.”
First approved for U.S. supply in 1971, soft contact lenses sales reached $1 million in the first six months. What made them so popular among contact lens wearers? Soft contact lenses are generally more comfortable to wear. They are able to stay in place better and are easier to adjust to than hard contact lenses. The flexible plastic is combined with water to allow oxygen to pass through the contact lens to the cornea.
Orthokeratology, or Ortho-K, is a lens fitting procedure that uses specially designed rigid gas permeable (RGP) contact lenses to change the curvature of the cornea to temporarily improve the eye’s ability to focus on objects. This procedure is primarily used for the correction of myopia (nearsightedness).
A stye is a pimple or abscess that forms in either the upper or lower eyelid. It is an inflammation caused by blockage of an oil duct and bacteria that normally live on the surface of the eyelid without any problems. Some germs can get trapped along with dead skin cells along the edge of the eyelid. Styes are usually superficial and plainly visible. Occasionally, they can reside deeper within the eyelid.
What Is Pinkeye?
Pinkeye, also called conjunctivitis, is redness and inflammation of the clear membranes covering the whites of the eyes and the membranes on the inner part of the eyelids. Pinkeye is most often caused by a virus or by a bacterial infection, although allergies, chemical agents, and underlying diseases can also play a role.
Ocular migraines cause vision loss or blindness lasting less than an hour, along with or following a migraine headache. Experts sometimes call these episodes "retinal," "ophthalmic," or "monocular" (meaning one eye) migraines.
When fluid inside the eye doesn't drain properly, pressure can build up. The increase in pressure can damage nerves and the blood vessels in the eye, causing changes in vision.
Orthokeratology is a non-chirurgical procedure, it is the replacement for glasses and eye contact lenses.
It's not always easy to pinpoint an exact reason why a child isn't doing well in school. Frequently, learning difficulties are due to a combination of problems. But when children struggle in school or perform below their potential, an undiagnosed vision problem may be the cause.
Over 10 million children suffer from undetected vision problems in the United States. Almost 1 out of every 5 school-aged children struggles with reading. Some suffer from dyslexia or a learning disability, but a large number of these children have something in common. Their language processing and phonetic awareness skills are intact; their vision is not. Vision is often the hidden problem that keeps students from doing well in school.
