Myopia And Hyperopia: What Is The Difference And How Are They Caused?

Myopia Management - Eyedeology Calgary

What is the difference between Nearsightedness (Myopia) and Farsightedness (Hyperopia)

In order to see properly, the front surface of our eyes, the cornea, needs to correctly focus light into the back of the eyes called the retina, where our vision receptors are located. This process is called refraction, and when done incorrectly, the “refractive error” will result in blurriness in vision. Both nearsightedness and farsightedness are types of refractive errors that indicate whether an individual can see clearly up close or at the distance.

Nearsightedness (Myopia)

Nearsightedness, as the name implies, is a condition where an individual sees nearby objects well but has difficulty seeing in the distance. Nearsightedness is synonymous with myopia. It is a type of refractive error where light is focused in front of the retina, causing blurriness in distance vision. There are two main reasons behind this condition. One is that the eyeball has grown too long, and the cornea is not strong enough to focus the light farther into the eye. Another reason is that the cornea is too curved, and therefore too strong, and focuses the light into the eye sooner than it is supposed to. Myopia can occur at any age.

Farsightedness (Hyperopia)

Farsightedness, also called hyperopia, is a condition where an individual sees fine in the distance but has trouble reading or seeing objects up close. It occurs when light is not focused enough and is focused behind the retina instead. This could be a result of eyeballs that are too short or a cornea that is too flat and therefore, not strong enough to focus light where it needs to. Individuals with hyperopia will experience eye fatigue, headaches and discomfort when looking at near objects, due to the additional demand placed on their eyes to increase their ability to focus.

Both myopia and hyperopia are refractive errors that are typically corrected with glasses and/or contact lenses. These corrective aids are used to support the eyes, with the goal of focusing light directly on the retina and therefore eliminating blurriness in the near, if it is hyperopia, and the distance, if the individual has myopia. If an individual experiences blurriness in both near and distance, multifocal glasses and contact lenses are available to aid in the ability to see objects at various distances. Refractive surgery is also another option when trying to correct these refractive errors.

It is best to see your optometrist when experiencing blurry vision to determine the root cause of your symptoms, as these vision problems may or may not be due to refractive errors such as myopia or hyperopia. Annual eye exams are vital in ensuring that you are seeing the world as you should be. If you were determined to have refractive errors in your vision, your optometrist will be able to suggest the type of refractive correction that best suit your lifestyle. If you have any questions about near- or farsightedness or are experiencing any problems with your vision, feel free to contact Eyedeology at 587-353-5061 or send us an email at [email protected]

Supporting Ocular Surface Healing and Comfort

The membrane contains natural growth factors and anti-inflammatory properties. When placed over the cornea, it acts as a protective layer that supports healing and may help reduce inflammation.

Potential Benefits

  • Supports Healing: Helps promote natural healing of the eye’s surface.
  • Reduces Inflammation: Its natural properties may help calm inflammation.
  • Improves Comfort: May help relieve discomfort related to dry eye.
  • Supports Recovery: Helps support the healing of the ocular surface.

Who May Benefit?

Amniotic Membrane Therapy may be suitable for people with moderate to severe dry eye, particularly when conventional treatments have not provided enough relief. An eye care professional can assess your eyes and determine if this treatment is appropriate.

How Does It Work?

The amniotic membrane is the innermost layer of the placenta and contains growth factors and anti-inflammatory properties. During treatment, a specially prepared membrane is placed over the eye’s surface to act as a biological covering and support healing.

What to Expect

Before treatment, your optometrist will examine your eyes and determine whether Amniotic Membrane Therapy is suitable for you.

  • Before Treatment: The eye is numbed with topical anesthetic drops, and the area is prepared.
  • Membrane Placement: The preserved and sterilized membrane is placed over the cornea.
  • After Placement: A special contact lens may be used to hold the membrane in place.
  • Post-Treatment Care: Antibiotic or anti-inflammatory eye drops may be prescribed when needed.
  • Follow-Up: Regular visits help monitor healing and the membrane’s absorption or integration.
Some patients may experience mild discomfort, a foreign body sensation, or temporary blurred vision after treatment. Improvement in symptoms may take anywhere from a few days to several weeks, depending on the individual.

Understanding Dry Eye and Your Treatment Options

Dry eye can develop for several reasons, and understanding the underlying cause is an important part of managing symptoms. Our team can assess your eyes and help develop a management plan based on your individual needs.

Common Symptoms of Dry Eye

Dry eye can affect both eyes and may cause different symptoms, including:

  • Stinging or Burning – A burning, stinging, or gritty feeling in the eyes.
  • Eye Redness – Red or irritated eyes.
  • Light Sensitivity – Increased sensitivity to light.
  • Excessive Watering – Eyes that water more than usual.
  • Blurred Vision or Eye Fatigue – Blurry vision or tired, strained eyes.
  • Foreign Body Sensation – A feeling that something is in your eye.

What Causes Dry Eye?

A healthy tear film has several components that work together to keep the surface of the eye comfortable and protected. Dry eye can occur when tear production decreases or when tears evaporate too quickly.

Several factors may contribute to dry eye, including:

  • Aging
  • Allergies
  • Hormonal changes
  • Eyelid problems
  • Gland dysfunction
  • Certain health conditions
  • Living in a dry climate
  • Extended screen time

One common factor is blockage of the Meibomian glands, which produce the lipid layer of the tear film. When these glands are not functioning properly, tear evaporation can increase and contribute to dry eye symptoms.

A Personalized Approach to Dry Eye Management

Managing dry eye involves more than simply using eye drops. Our team can help develop a personalized plan that may include targeted in-office treatments, nutritional guidance, and home care based on your needs. 

Home care may include:

  • Warm Compresses: Used as part of a regular eye-care routine.
  • Lid Hygiene: Keeping the eyelids and surrounding area clean.
  • Artificial Tears: May be recommended to help manage dryness and discomfort.

In-Office Treatment Options

For patients with more severe dry eye symptoms, targeted in-office treatments may be considered. Available options include:

  • Radiofrequency
  • Intense Pulsed Light Therapy (IPL)
  • LipiFlow Therapy

These treatments may be used as part of dry eye management for symptoms such as burning, itching, redness, and irritation. The appropriate approach depends on the underlying factors contributing to your symptoms.

Managing Your Dry Eye Symptoms

Dry eye can have several contributing factors, so treatment is not the same for everyone. A thorough assessment can help identify factors affecting your tear film and determine which management options may be appropriate.

If you are experiencing persistent dryness, irritation, redness, light sensitivity, or other symptoms, speak with our eye care team about your dry eye management options.

Deep Cleansing for Healthier Eyelids and Lashes

ZEST (Zocular Eyelid System Treatment) is an in-office eyelid cleaning and debridement treatment developed by Zocular®. It is designed to clean the eyelids and lashes while helping address concerns associated with dry eye, blepharitis, and demodex.

The treatment uses a natural, okra-based gel to remove oil, debris, and residue from the eyelid margins and lashes. By improving eyelid hygiene, ZEST can help reduce the buildup that may contribute to irritation and inflammation around the eyes.

What Is ZEST?

ZEST works like a deep cleansing treatment for the eyelids and lashes. During the procedure, the okra-based gel is applied along the eyelid margins and lashes using a cotton swab. The gel is gently worked into a lather using circular motions before being rinsed away with saline solution.
The gel contains a refined extract of okra, an edible green seed pod. According to the provided product information, okra helps lift and clear oil, debris, and residue while being gentle around the eye area.

How Can ZEST Help?

Keeping the eyelids, eyelid margins, and lashes clean is an important part of eye hygiene. Buildup along the eyelid edges can contribute to symptoms such as itching, burning, gritty sensations, redness, and irritation.

ZEST is designed to address this buildup through thorough cleansing and debridement.

  • Removes Debris: Helps clear dirt, oil, and residue from the eyelid margins and lashes.
  • Supports Eyelid Hygiene: Provides a deeper cleansing treatment than routine eyelid cleaning.
    Addresses Demodex: The treatment is designed to help remove demodex mites and associated debris.
  • Helps Reduce Inflammation: Cleansing the eyelid area may help address buildup associated with irritation and inflammation.
  • Supports Dry Eye Care: ZEST may help relieve symptoms associated with dry eye and poor eyelid hygiene.

ZEST for Dry Eye, Blepharitis, and Demodex

Dry eye and blepharitis can be associated with inadequate eyelid hygiene. Debris along the eyelid margins can enter the tear film with blinking, potentially contributing to redness and irritation.

Demodex mites can also be present in the hair follicles around the eyelashes. According to the provided information, they may contribute to inflammation and dry eye symptoms by blocking the oil glands at the base of the eyelashes.

ZEST provides targeted cleansing of the eyelid margins and lashes to help remove this buildup and address demodex-related concerns.

A Simple In-Office Treatment

The ZEST procedure is performed in the office and involves applying the cleansing gel to the eyelid margins and lashes, working it into a lather, and then rinsing the area with saline solution. The treatment is designed to provide thorough eyelid and lash cleansing without requiring a lengthy procedure.

Is ZEST Right for You?

ZEST may be considered for patients experiencing symptoms associated with dry eye, blepharitis, demodex, or eyelid debris. An eye care professional can assess your symptoms and determine whether ZEST is appropriate for your eye care needs.
