Chronic allergies may lead to permanent damage to the tissue of your eye and eyelids. If left untreated, it may even cause scarring of the conjunctiva, the membrane covering the inner eyelid that extends to the whites of the eyes. Ocular allergies can make contact lens wear almost impossible and are among the many causes of contact lens drop-out. Most common allergy medications will tend to dry out the eyes, and relying on nasal sprays containing corticosteroids can increase the pressure inside your eyes, causing other complications such as glaucoma.
Allergic conjunctivitis is the clinical term for inflammation of the lining or membrane of the eye, called the conjunctiva, caused by allergic reactions to substances. Although a patient may present with red or pink eyes from excess inflammation, the common term "pink eye" can signify a broad range of conditions and can be misleading, as viruses, bacteria, fungi, and other irritating substances can cause redness resembling a "pink eye." Your eye doctor can differentiate between an allergy and a true infection, which can lead to faster healing with the right treatment.
Astigmatism is usually caused by an irregularly shaped cornea, the front surface of the eye. Instead of being a perfect sphere, like a ball bearing or a marble, it can become a little more like a football, being more curved in one direction than the other. This brings light into focus at more than one point on the retina at the back of the eye, resulting in blurry or distorted vision.
Stigma is actually referring to a type of refractive error known properly as astigmatism, and no, you will not go blind from having astigmatism; it is not a disease. In fact, this condition is relatively common. There are three types of refractive errors: myopia, hyperopia and astigmatism. The former two are also known to as nearsighted (cannot see far away) and farsighted (cannot see up close). Astigmatism is simply the third category; it can affect both the near and far vision. Much like nearsightedness or farsightedness, astigmatism is corrected using glasses or contacts. Technically speaking an eye with astigmatism requires two different prescriptions to correct vision in one eye, due to the more oval shape of the cornea. For contact lens wearers, this will require a more specialized contact lens and a more in-depth fitting procedure.
Blue light is part of visible light and has a wavelength close to UV rays on the light spectrum. It is naturally produced by the sun, given off by fluorescent light bulbs, and emitted by LED screens on computer monitors, tablets, and smartphones. The eye's natural filters do not block blue light and chronic exposure may increase your risk for age-related macular degeneration. Evidence also shows that blue light exposure can lead to sleep problems.
Reading from a tablet or smartphone in the dark is okay for your eyes, as long as it's not for a long period of time. These devices have decent lighting and good contrast. However, they give off blue light, and long-term exposure may cause damage to the structures of the eye. As well, studies have shown that blue light at night disrupts melatonin production and interferes with healthy sleep cycles. Optometrists recommend wearing blue light blocking eyewear for extended digital device use, and limiting screen time during the last hour before bedtime.
The last few years have seen a radical shift in how our children use their vision. More and more time is spent looking at an electronic screen; TV, computer, cell phone, game device, and so on. Vision scientists have long pointed out that excessive near point tasks can lead to increased myopia (nearsightedness) in children, eyestrain, and headaches. Combined with the potentially damaging effect of the blue light these screens emit, you have the possibility of a dangerous situation. We recommend a common-sense approach. First, limit the time your child has to electronic media. Psychologists, educators, and doctors all agree: too much is not good. Second, practice the 20/20/20 rule. For every twenty minutes of near point tasks, take twenty seconds and look at something twenty feet or more away. In short, take frequent rest breaks. Third, use lenses that are designed for your particular activity. Having the correct eyeglass or contact lens prescription is always the place to start. There are lenses and coatings that not only provide the proper focus, but also block unwanted glare and limit the amount of damaging blue light.
Paragon CRT® Contact Lenses are therapeutic contact lenses that gently remold the cornea while you sleep to temporarily correct nearsightedness up to -6.00 diopters, and mild amounts of astigmatism. If you or your child have been diagnosed with nearsightedness (or myopia), Paragon CRT® Contact Lenses offers a non-invasive and non-surgical treatment.
Glaucoma is a condition in which the eye's intraocular pressure (IOP) is too high. This means that your eye has too much aqueous humor in it, either because it produced too much, or because it's not draining properly. Other symptoms are optic nerve damage and vision loss. Glaucoma is a silent disease that robs the patient of their peripheral vision. Early detection is very important.
Myopia is caused by a combination of environmental factors and heredity. Studies show that if we can move the focal point in front of the mid peripheral retina we can slow the progression of myopia. The increased use of cell phones and computers, as well as less time outdoors is probably a contributing factor.
It has been concluded in many studies that orthokeratology will halt or slow down the increase of axial length of the eye which is directly correlated to halting or slowing down progression of myopia.
I love practicing orthokeratology because of the myopia control aspect. It's great to keep a child's nearsightedness from increasing exponentially and by doing that it will decrease the child's risk of developing retinal detachment or glaucoma in the future.
People who suffer from nearsightedness will benefit the most from CRT, especially if your eye doctor does not recommend refractive surgery. Patients of any age can benefit from this treatment. Corneal reshaping lenses are especially useful for people who find eyeglasses and contact lenses inconvenient for various reasons. Some people find contacts hard to wear for an entire day, or don’t want to wear them while playing sports.People who suffer from dry eye syndrome or allergies have a hard time wearing contacts. Ortho-k is a perfect solution for anyone who can’t wear contact lenses, and don’t like the look or feel of eyeglasses.
After one or two nights of wearing the lenses, you will notice that your vision has improved. It could take a bit longer to reach perfect vision. Most people report achieving clear and sharp vision within two weeks. FDA trials have shown that approximately 65% of all patients who use CRT achieve 20/20 visual acuity.
Vision therapy is an individualized treatment plan prescribed by a Doctor of Optometry. It is used to treat eye conditions, such as strabismus (eye turn) or amblyopia (“lazy eye”). Through Vision Therapy, a Doctor of Optometry also teaches, improves and/or reinforces important visual skills, such as eye tracking, eye focusing and eye teaming abilities. Without these visual skills, simple tasks like reading or copying notes from the board become difficult. Skipping words or lines while reading, using a finger while reading, blurry near vision, double vision, eyestrain and/or eye fatigue are also common symptoms.
If your child displays symptoms of strabismus (eye turn), amblyopia (“lazy eye”), skipping words or lines while reading, using a finger while reading, blurry near vision, double vision, eyestrain and/or eye fatigue, it is suggested your child has a complete eye exam from a Doctor of Optometry. If symptoms persist or the Doctor of Optometry recommends Vision Therapy, then a Vision Therapy assessment is the next step. The doctor will perform a thorough one-on-one assessment and will determine which conditions are present, whether Vision Therapy is suitable, the type of eye exercises required and the number of sessions needed.
An optometrist is a healthcare professional who is licensed to provide vision care. This typically includes eye exams, vision tests, and diagnosis of eye diseases and conditions. Optometrists fit patients with glasses or contact lenses for common refractive errors like myopia (nearsightedness), hyperopia (farsightedness), astigmatism, or presbyopia (farsightedness due to aging).
An ophthalmologist is a medical doctor who is licensed to practice medicine and perform vision-related surgical procedures. They receive years of advanced medical training to diagnose eye diseases and provide treatments, conduct scientific research on vision disorders, and prescribe medications for their patients.
Health insurance covers the cost of basic healthcare needs, such as physical exams, emergency care, medically necessary procedures, and some prescription drugs. Many health insurance plans include coverage for sudden eye injuries or disease, but not general vision care.
A vision plan covers the cost of care for maintaining healthy vision. This can include annual eye exams, vision tests, some eye surgeries, and prescription eye medications. Some vision plans cover prescription eyeglasses or contact lenses either at reduced cost or offer discounts.
