What You Should Know About Night Blindness

Our Optometrist in Petrolia, explains About The Causes of Night Blindness

Our eye doctor can help diagnose, manage and treat your night blindness so that you can enjoy being out at night again.

Here are 4 things you should know about night blindness:

The inability to see well at night can be the result of a condition such as:

  • Vitamin A Deficiency Vitamin A helps keep your cornea, the layer at the front of your eye, clear; it’s also an important component of rhodopsin, a protein that enables you to see in low light conditions. Although uncommon in North America, deficiency of this vitamin can induce night blindness.
  • Cataracts
    A buildup of protein clouds the eye’s lens, leading to impaired vision, especially at night and in poor lighting conditions.
  • Diabetic retinopathy
    Damage to the eyes’ blood vessels and nerves can result in vision loss, including difficulty seeing at night.
  • Glaucoma
    This group of eye diseases is associated with pressure build-up in the eye that damages the optic nerve. Both Glaucoma and the medications used to treat it can cause night blindness.
  • Myopia
    Also called nearsightedness, Myopia makes distant objects appear blurry, and patients with it describe a starburst effect around lights at night.
  • Keratoconus
    An irregularly shaped cornea causes blurred vision and may involve sensitivity to light and glare which tend to be worse at night.
  • Retinitis Pigmentosa (RP)
    A progressive genetic eye disease which can be associated with other diseases, RP leads to night blindness and peripheral vision loss.
  • Usher Syndrome
    This genetic condition causes both hearing loss and vision loss, including night blindness and RP, mentioned above.

Symptoms of Nyctalopia

Since night blindness is a symptom of some serious vision problems, it’s important to get your eyes checked regularly to ensure that everything is in good working order. Contact your eye doctor as soon as possible if you notice that you don’t see as well in dim light as you used to, such as when driving at night or when adjusting from being outdoors in the sunshine to being indoors.

Symptoms of Night Blindness Include:

  • Reduced contrast sensitivity
  • Difficulty seeing people outdoors at night
  • Difficulty seeing in places with dim lighting, like a movie theater
  • Trouble adapting to the dark while driving
  • Excessive squinting at night
  • Trouble adjusting from bright areas to darker ones

Treatments for Night Blindness

Your eye doctor will want to diagnose the cause of your night blindness in order to treat it. For example, in the rare case of vitamin A deficiency, it can be treated with vitamin supplements and vitamin-A rich foods; Myopia can be corrected with eyeglasses or contact lenses. Other conditions may require medications or surgery.

If night blindness is caused by a birth defect, Usher syndrome, or retinitis pigmentosa, low vision aids and devices can help you make the most of your remaining vision.

Prevention

While there is no proven way to prevent night blindness resulting from genetic conditions or birth defects, consuming healthy, nourishing foods and taking certain vitamin supplements may prevent or slow the onset of some eye conditions that cause night blindness.

If you experience poor vision at night or in dim lighting, we can help. Contact Petrolia Optometry in Petrolia to schedule your appointment today.

Frequently asked questions answered by our Eye Doctor in Petrolia, Ontario:

  • What are the reasons for Cataract Removal?

    Cataracts can interfere with your ability to live normally. They may make it impossible to drive, read, use a computer, watch TV, climb staircases, or identify faces. Cataracts can also get in the way of medical treatment for other eye diseases, such as macular degeneration or diabetic retinopathy because they prevent your eye doctor from inspecting the back tissues of your eye thoroughly. These are all reasons why your eye doctor may recommend cataract surgery.

  • Why Diabetic Eye Exams are Essential?

    At present, one in 10 Americans has diabetes – and the trend is continuing upwards. While routine comprehensive eye exams are important for diagnosing the early signs of diabetes, that doesn’t mean eye exams become insignificant after diagnosis!

  • What is glaucoma?

    Glaucoma describes a type of ocular disease that causes damage to your optic nerve and destroys your quality of vision. With no early symptoms, glaucoma can only be detected by a complete eye examination. When left untreated, glaucoma can result in detrimental vision loss. When treated early by one of our professional, knowledgeable eye doctors, we can help preserve your healthy eyesight.

  • What is Myopia?

    Cataracts can interfere with your ability to live normally. They may make it impossible to drive, read, use a computer, watch TV, climb staircases, or identify faces. Cataracts can also get in the way of medical treatment for other eye diseases, such as macular degeneration or diabetic retinopathy because they prevent your eye doctor from inspecting the back tissues of your eye thoroughly. These are all reasons why your eye doctor may recommend cataract surgery.

Petrolia contact lenses, Are contact lenses better than glasses?

Petrolia Optometry Eye Clinic in Petrolia, Ontario

Do contacts make your vision worse?

You have just visited our eye care clinic for an eye exam in Petrolia, Ontario and you received a new vision prescription. Now it is time to purchase new eyewear – should you buy eyeglasses or contact lenses? As long as your eyes are healthy, the choice is yours.

Many differences exist between glasses and contact lenses, and people wonder whether one type of eyewear is more effective and more suitable for their lifestyle. To help you make an educated decision, Dr. St. Pierre, your optometrist for Petrolia and the Petrolia area, has put together this outline of what you need to know about glasses and contact lenses.

Many eye diseases can be quickly and easily diagnosed during a Comprehensive eye exam, Pediatric eye exam and Contact lens eye exam. If you were diagnosed with an eye disease, such as Cataracts, Glaucoma, Macular degeneration, Diabetic retinopathy, or Dry eye, you may be overwhelmed by the diagnosis and confused about what happens next. Will you need medications or surgery – now or in the future? Is LASIK eye and vision surgery an option for you ? Our Petrolia eye doctor is always ready to answer your questions about eye disease and Contact lenses.

Features Shared by Glasses & Contacts

First of all, let’s look at the similarities between contacts and eyeglasses:

    • Both can precisely treat nearsightedness, farsightedness, and astigmatism to give you sharp vision
  • You need to clean them properly to ensure crystal-clear vision; with glasses, this means spraying and wiping the lenses, and with contacts, there are varying degrees of care (depending upon which type you select)
  • Both glasses and contacts are affordable

All About Eyeglasses

Nowadays, glasses are made from plastic, making them much lighter than years ago. Also, plastic lenses can be coated with various treatments to protect your eyes, such as against dangerous UV light or to block blue light from digital devices. Polycarbonate or Trivex lenses are ideal for children and people who play sports because they do not shatter on impact. Another option for people with very strong prescriptions is high index lenses, which are a thinner and lighter form of vision correction.

There are two primary types of glasses: single vision and multifocal. Single vision eyeglasses correct problems with seeing close or seeing far, while multifocal glasses help with seeing both distance and near-vision issues.

Multifocals come in a few versions:

  • Bifocal lenses are bisected into two zones. The upper half helps with seeing distance and the lower half of the lens helps with reading and other close tasks.
  • Trifocals have three areas in the lenses. The top is for distance, the bottom is for up close, and the region between the two is for middle vision.
  • Progressive lenses are essentially the same as bifocals and trifocals, yet with no dividing line in the lens. The visual transition between the different lens powers is gradual and smooth.

What’s Good About Glasses, and What’s Not

Pros:

  • Eyeglasses are easy to use. You just put them on your face and out you go. There are no specialized cleaning solutions and care is minimal. If you have a particular style or fashion statement you want to make with your glasses, a range of frame designs is available from our optometrist for Petrolia. Also, if you work in a job that leaves your fingers dirty all the time, you don’t need to touch your eyes when putting on glasses. So the risk of eye infection is very low.

Cons:

  • The main disadvantage of eyeglasses relates to how they look and feel. Many people simply don’t like their appearance in glasses. Also, you also may find them uncomfortable on your nose or pressing above your ears. Another con of glasses is that the lenses can fog up, get splashed in rainy weather, and fall off (or slip down your sweaty nose) during sports. The plastic lenses can also scratch.

All About Contact Lenses

Contacts are thin discs made from either glass or plastic, depending upon whether you have soft or hard (GP) lenses. These discs rest directly on your eye to correct vision. Our Petrolia contact lenses collection includes a full inventory of single vision, bifocal, and multifocal versions. Soft contact lenses, which are much more popular, come in several types:

  • Daily wear lenses: worn during the day; removed and cleaned nightly
  • Daily disposables (dailies): worn once and then thrown away
  • Extended wear lenses: can be worn overnight; taken out at least once a week for disinfecting

What’s Good About Contacts, and What’s Not

Pros:

  • Contact lenses provide more natural vision than eyeglasses, as well as a more natural appearance that doesn’t block your face. They give a wider field of view and a clear peripheral vision. Because contacts move with your eye, no frame ever gets in your way or disturbs your line of sight. Also, contacts never fog up or get splashed with water droplets when it rains. When playing sports, contact lenses can be ultra-convenient.

Cons:

  • Contacts require higher maintenance than glasses. You must clean and store them properly or you risk getting serious eye infections. If you have high astigmatism, contacts may not be able to provide sharp vision all the time – because you’ll see blurry when they rotate. Toric contacts, which are specialized for astigmatism, have less of a tendency to move around, but they are more costly. You may also need a short adjustment period to adapt to wearing contacts, and more follow-up care from our optometrist for Petrolia.

That’s the basic rundown of contact lenses versus eyeglasses! Dr. St. Pierre provides comprehensive eye exams for Petrolia and the entire Petrolia area, and he will issue your accurate, up-to-date prescription for eyewear. Our optical staff will then be pleased to assist you with your decision whether to choose glasses, contact lenses or both!

Petrolia, What is Pink eye?

Petrolia Optometry Eye Doctor in Petrolia, Ontario

What are pink eye symptoms?

Think you have pink eye? Contact our Petrolia eye doctor for diagnosis & treatment Pink eye is pretty common, but there’s nothing pretty about this condition! Not only do pink eyes look ghoulish, but they can also hurt.

What is pink eye?

Officially called conjunctivitis, pink eye is caused by swelling in your eye. The conjunctiva – which is the thin and transparent tissue that lines your inner eyelids and coats the whites of your eyes – becomes inflamed. This eye infection is highly contagious, especially in kids, and it spreads quickly through schools. The good news is that pink eye is rarely serious and doesn’t usually cause any lasting damage to your vision.

There are several types of conjunctivitis, and the best treatment depends largely upon whether you have mild pink eye symptoms, allergic pink eye symptoms, bacterial pink eye symptoms, or pink eye symptoms with fever.

Many eye diseases can be quickly and easily diagnosed during a Comprehensive eye exam, Pediatric eye exam and Contact lens eye exam. If you were diagnosed with an eye disease, such as Cataracts, Glaucoma, Macular degeneration, Diabetic retinopathy, or Dry eye, you may be overwhelmed by the diagnosis and confused about what happens next. Will you need medications or surgery – now or in the future? Is LASIK eye and vision surgery an option for you ? Our Petrolia eye doctor is always ready to answer your questions about eye disease and Contact lenses.

Local Eye clinic in Petrolia, Ontario

At Petrolia Optometry, we diagnose and treat conjunctivitis regularly. To keep you informed about pink eye and ready to cope if it happens to you or any member of your family, our Petrolia, Ontario, eye doctor has prepared the following Q & A:

I have swollen, itchy, and pink eyes. What should I do?

Don’t delay – contact us at Petrolia Optometry to book an urgent eye exam. It is important to get a precise diagnosis as soon as possible. That’s the only way to ensure that you are receiving the best treatment. When you follow our Petrolia eye doctor’s recommendations, your pink eye should clear up quickly with no lasting complications.

What are pink eye symptoms?

The most common symptoms of pink eye include:

  • Itchy eyes
  • Red eyes and redness in the inner eyelid
  • More tears than usual
  • Swollen conjunctiva
  • Burning or stinging eyes
  • Green or yellow discharge from the eye
  • Increased sensitivity to light
  • Blurry vision
  • Swollen lymph nodes (from a virus)

Depending on how serious your eye infection is, you may experience mild pink eye symptoms or more severe pink eye symptoms with fever.

What are the causes of pink eye?

The most typical causes of pink eye are:

  • Bacteria
  • Viruses, including the common cold
  • Fungi, parasites, and amoebas
  • Irritants, such as smoke, chlorine, shampoo and dirt
  • Reaction to eye drops or medication
  • Allergic reaction to dust, smoke, pet dander, or pollen; some people are also allergic to specific contact lens solutions

Why does it matter what caused my pink eye?

In order to treat pink eye effectively, it’s important to have an eye exam to determine the root of the problem. Our Petrolia, Ontario, the optometrist will evaluate your condition thoroughly and recommend the most helpful, personalized treatment.

Your pink eye symptoms can often point to the root of the problem. For example, pink eye caused by a virus (the most common and probably the most contagious!) usually starts in one eye and spreads to the second eye within a few days. In contrast, bacterial pink eye symptoms generally affect one eye but can be present in both, and these infections usually create a lot of oozing mucus. And allergic pink eye symptoms are usually characterized by itchy eyes, tearing, and redness (often accompanied by a runny, itchy nose).

What pink eye treatment brings relief?

As soon as you have an eye exam at Petrolia Optometry, we’ll treat your condition with the best therapy to alleviate your symptoms and heal the infection.

  • If you have bacterial pink eye, you will need to take antibiotics – either as eye drops, ointments, or pills. This type of infection usually clears up within a week.
  • If a virus caused your case of pink eye, there’s little to do but let the virus run its course.
  • When pink eye is caused by an irritating substance, you can rinse your eye with water for a few minutes. This generally brings relief and your eyes should start to heal within a few hours.
  • Allergic pink eye symptoms should improve as soon as you receive allergy medication and/or avoid the allergen that is your trigger. Antihistamines will offer some pink eye relief, especially from itchy eyes.

Visit your Petrolia, Ontario, eye doctor for pink eye diagnosis and treatment Our emergency eye doctor at Petrolia Optometry will perform an urgent eye exam to assess your condition and prescribe treatment. If you suspect that you have pink eye, contact our office for assistance.
