What You Should Know About Night Blindness

Our Optometrist in Mooresville, 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.

Frequently asked questions answered by our Eye Doctor in Mooresville, North Carolina:

  • 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.

The Importance of Eye Exams for Contact Lenses

Are you planning on wearing contact lenses for the first time? Do you need a new contact lens prescription? Are your current contacts not as comfortable as you wish they were? Your eye doctor will perform a contact lens eye exam to ensure that your vision with contacts is clear, comfortable, and safe, providing you with the right lenses for you.

What is a contact lens exam?

If you wear or want to wear contact lenses, you’ll need an eye exam for contact lenses, in addition to your regular comprehensive eye exam. Special tests are performed during a contact lens exam to evaluate your eyes and vision with contacts.

Are eyeglass prescriptions the same as contact lens prescriptions?

No, a prescription for glasses cannot be used for contact lenses. An eyeglass prescription is for lenses that are positioned approximately 12 millimeters from your eyes, whereas a contact lens prescription is measured for lenses that sit directly on the surface of your eye.

The prescription for contact lenses also includes the brand, lens diameter and curvature, which are not part of an eyeglass prescription.

Many eye diseases can be quickly and easily diagnosed during a comprehensive 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? Our Mooresville eye doctor has prepared the following answers to your questions about eye disease.

Contact lenses fitting: One size does not fit all

One contact lens size doesn’t fit all eyes. If a contact lens is too flat or too steep for your corneal shape, you may experience discomfort or even eye damage. Your eye doctor will take certain measurements to determine the best contact lens design and fit for your eyes.

Corneal curvature

This measures the curvature of your eye’s clear front surface (cornea) so the eye doctor can select the optimal curve and diameter for your contact lenses. If your eye’s surface is somewhat irregular because of astigmatism or other conditions, you may require a special lens.

Pupil and iris size

The size of your pupil and iris (the colored part of your eye) is also important in determining the best contact lens design.

Tear film evaluation

This test evaluates the quality of your tears, to determine whether they will be able to keep contact lenses and your cornea sufficiently hydrated throughout the day. If you have dry eye disease, standard contact lenses may not be right for you.

Trial lenses

Following the eye exam, you will be provided with trial lenses to verify that the chosen contact lenses offer clear and comfortable vision. This will allow the eye doctor to make any fine adjustments to the prescription.

Wearing the correct contact lenses for your eyes allows you to enjoy all of the benefits of wearing contacts, while keeping your eyes healthy and comfortable.

If you’re already a contact lens wearer, visit your eye doctor at least once a year to make sure the lenses are still providing you with optimum vision and comfort.

New To Contact Lenses? Here Are Our Top 5 Tips!

For an estimated 56 million North Americans, contact lenses are the preferred form of vision correction. So if you’ve just started wearing contact lenses — you’re in good company.

Advice About Contact Lenses from Mooresville Eye Doctor: Dr. Angela Harris Here are 5 tips to quickly help you adjust to wearing and caring for your new lenses so you can enjoy the many benefits they offer.

Learn How to Tell if Your Contact Lens Is Inside Out

This is a common mistake many beginners make when inserting soft contacts. Place the lens on your index fingertip and look carefully at its shape. The edge of the lens should be pointing upwards, like the rim of a teacup. If the edge is flared outward like a blooming flower, the lens is inside out.

Some contact lenses have tiny laser markings of numbers or letters. If the numbers/letters read correctly when you hold the lens on your fingertip, they are properly oriented and the lens is ready to be inserted.

Never Use a Substitute for Contact Lens Solution

Your eye doctor will recommend the appropriate contact lens solution to suit your eyes and lenses. Some people have sensitivities and not all lens solutions are the same.

Even if you run out of contact lens solution, don’t be tempted to rinse your lenses with water, and never use saliva to moisten or clean them.

Using substances other than the recommended contact lens solution to rinse or rewet your contacts can introduce harmful microbes to the eye and cause a serious infection. That’s why it’s best to remove your contacts before showering, swimming, or any other time they might get wet.

Many eye diseases can be quickly and easily diagnosed during a comprehensive 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? Our Mooresville eye doctor has prepared the following answers to your questions about eye disease.

If Your Contact Lenses Feel Uncomfortable, Take Them Out!

Some newcomers mistakenly think that if their contacts feel uncomfortable or gritty, they simply need to “get used to them.” Contact lenses are supposed to be comfortable, so if you are experiencing discomfort there may be something wrong.

With clean fingers, remove your contacts and rinse them, inside and out, with the solution or rewetting drops as recommended by your eye doctor. Dust or dirt could have gotten stuck between the lens and your eye, causing irritation. Flushing the lenses with contact lens solution will help remove the irritant.

If your eyes still feel irritated, don’t place the contact lenses back in your eyes. Instead, wait until they are no longer red or irritated, and try inserting them again. If the problem persists, contact your eye doctor.

Wear Contact Lens-Friendly Makeup

Wearing makeup around the eyes can be a source of irritation and infection whether you wear contact lenses or not. Here’s what we recommend when it comes to eye makeup and contact lenses:

  • Choose hypoallergenic makeup.
  • If using a cream-based product around your eyes, choose a water-based formula instead of an oil-based one.
  • Keep your eye closed during application to avoid makeup particles entering your eye.
  • Don’t apply eyeliner or eyeshadow to the inner rims of your eyelids.
  • Replace eye makeup at least once every 3 months to minimize the growth and spread of bacteria.
  • Never share eye makeup with friends or family.
  • Remove your contact lenses before removing your makeup.

Stick to the Hygiene Guidelines

We can’t emphasize this enough — always thoroughly wash and dry your hands before handling your contact lenses.

Try to avoid washing your hands with oily or heavily scented hand soaps, as they tend to cling to the surface of the lens and could irritate the eye. Additionally, if you touch moisturizers or lotions before handling your contact lenses you run the risk of some residual product adhering to the lens and clouding your vision.

After washing your hands, dry them using a lint-free towel. It’s harder to grasp contact lenses with wet hands, and — as mentioned above — lenses shouldn’t come into contact with tap water.

Bonus Tip: Get an Eye Exam

While all this advice can be very helpful, it doesn’t replace an in-person exam with your eye doctor. Your eye doctor will advise you when to return for your next contact lens consultation. Following this schedule is the best way to ensure you can enjoy the freedom of contact lens wear.

If you are new to contact lenses (or not!) and have any questions or concerns about your eyes or vision, call 704-327-5545. Lake Norman Eye Care will be happy to schedule you for a contact lens exam and fitting.

With the help of Dr. Angela Harris, you’ll be an expert in contact lens wear and care in no time!
