What Is Myopia? Causes, Symptoms, and Treatment

Last Updated: 21/10/2026

Myopia, also called nearsightedness, is a common refractive error in which nearby objects look clear but distant objects appear blurry. It happens when light focuses in front of the retina instead of directly on it, usually because the eyeball is slightly longer than normal or the cornea is too curved.

Myopia often starts in childhood and may progress until early adulthood. It can be mild, needing glasses only for driving, or severe enough to require regular follow-up. The right treatment, whether glasses, contact lenses, or LASIK, depends on a proper eye exam that measures the degree of myopia and checks eye health.

What Is Myopia?

Myopia, or nearsightedness, is a refractive error that makes near vision clearer than distance vision. In a healthy eye, light focuses accurately on the retina. In myopia, the eye’s shape causes light to focus in front of the retina, leading to blurred distance vision.

This is why a patient may struggle to see road signs, a classroom board, or a distant screen, while still being able to read or see nearby objects more clearly.

Myopia does not always indicate a serious disease, but it should be assessed properly, especially if it develops quickly or affects school, work, driving, or daily activities.

What Causes Myopia?

Myopia usually develops because of the shape of the eye or the way light bends inside it. When the eyeball is longer than normal, or the cornea is too curved, light does not focus correctly on the retina.

Factors that may increase the likelihood of myopia include:

• Family history of myopia.
• Onset during childhood or adolescence.
• Long periods of near work, such as reading or screen use.
• Limited outdoor activity in children.
• Frequent changes in vision measurements.

Magrabi eye doctors emphasize that the cause of blurred distance vision cannot be confirmed from symptoms alone. Blurry vision may be caused by myopia or other refractive errors, which is why a full eye exam helps determine whether the patient needs prescription glasses, contact lenses, or further evaluation for vision correction options.

What Are the Symptoms of Myopia?

Myopia symptoms usually appear when trying to see distant objects. They may be mild at first, then become more noticeable if vision is not corrected properly.

Common symptoms include:

• Blurred distance vision.
• Difficulty seeing road signs or distant screens.
• Blurriness when looking far away.
• Squinting to see clearly.
• Headache or eye strain after visual effort.
• Difficulty driving, especially at night.
• Sitting close to the TV or classroom board.
• Reduced school performance if a child cannot see clearly in class.

Mayo Clinic notes that children may not always explain vision problems clearly, so myopia may appear through signs such as squinting or difficulty seeing the board, making an eye exam important when these signs are noticed.

How Is Myopia Diagnosed?

Myopia is diagnosed through an eye exam, not symptoms alone. Blurred distance vision may overlap with other issues such as astigmatism, dry eye, eye muscle problems, or retinal conditions.

A typical assessment may include:

• Visual acuity testing.
• Vision measurement to determine the degree of myopia.
• Refraction testing.
• Corneal assessment when needed.
• Retina and fundus examination in selected cases.
• Review of medical and family history.
• Assessment of vision stability if LASIK or Femto-LASIK is being considered.

Magrabi ophthalmologists explain that diagnosing myopia is not limited to measuring eyesight. It also includes evaluating the cornea, retina, and vision stability to choose the most suitable correction method, whether glasses, contact lenses, LASIK, or Femto-LASIK.

Corneal thickness becomes especially important before LASIK for myopia, because laser vision correction reshapes the cornea and is not suitable for every case.

What Are the Degrees of Myopia?

The degree of myopia is measured in diopters, the unit used to determine the lens power needed to correct vision.

In general, myopia may be classified as:

• Mild myopia: Distance vision is mildly blurred, and glasses may be needed for tasks such as driving or studying.
• Moderate myopia: Distance vision becomes more noticeably affected, and regular use of prescription glasses or contact lenses is often needed.
• Severe myopia: The myopia degree is high and may require closer medical follow-up, especially because some severe cases are linked with a higher risk of other eye problems.

NHS notes that adults with severe short-sightedness may have a higher risk of conditions such as glaucoma, retinal detachment, cataracts, and macular degeneration, which makes regular follow-up important in high degrees of myopia.

What Are the Treatment Options for Myopia?

Myopia treatment depends on the patient’s age, degree of myopia, lifestyle, eye health, and exam results. There is no single option that fits every patient.

Common treatment and correction options include:

Prescription Glasses

Prescription glasses are one of the most common ways to correct myopia. They help redirect light so it focuses properly on the retina, improving distance vision. Glasses are suitable for children, adults, and patients who do not want contact lenses or surgical procedures.

Contact Lenses

Contact lenses correct vision in a way similar to glasses, but they sit directly on the eye surface. They may be suitable for some patients, but they require proper hygiene and care to reduce the risk of irritation or infection.

LASIK and Femto-LASIK

LASIK and Femto-LASIK surgery may be used as part of vision correction surgery for selected cases of myopia, especially when vision is stable, corneal thickness is suitable, and there are no medical contraindications. LASIK reshapes the cornea to improve how light focuses on the retina.

 

Can Myopia Be Treated Without Surgery?

There is no home or natural remedy that corrects myopia. In most cases it is caused by the shape of the eye, either a slightly longer eyeball or a more curved cornea, and exercises, herbs, or foods cannot change that shape. Myopia can still be treated without surgery, in the sense that vision can be corrected with non-surgical options. In children, its progression can also be slowed under an ophthalmologist’s supervision.

Non-Surgical Options to Correct Myopia

These options improve distance vision without surgery. Your eye doctor recommends the most suitable one based on your age, the degree of myopia, and the condition of your cornea.

• Prescription glasses: The safest and most common option for all ages. They correct vision for as long as they are worn.
• Contact lenses: They give a wider field of view than glasses, but they need strict hygiene and correct wearing times to reduce the risk of irritation or infection.
• Orthokeratology lenses (Ortho-K): Rigid lenses worn overnight that temporarily reshape the surface of the cornea, so you can see clearly during the day without glasses. The effect wears off once you stop using them, and regular follow-up with your eye doctor is required.

Can Myopia Progression Be Slowed in Children?

Myopia can increase quickly during the school years. After examining the child, the ophthalmologist may recommend one of these myopia control options:

• Low-dose atropine eye drops, prescribed and monitored by the doctor.
• Specially designed glasses or contact lenses that help slow myopia progression.
• More time spent playing outdoors. Outdoor activity is linked to a lower chance of myopia developing in children.

These options do not return vision to normal, but they may slow how fast the prescription increases. They should only be used after a proper eye exam.

What Does Not Treat Myopia?

Many people look for ways to treat myopia naturally, but none of the following corrects myopia or replaces glasses or an eye exam:

• Eye exercises or focusing drills.
• Herbal remedies or eye drops that were not prescribed by a doctor.
• Carrots, vitamins, or dietary supplements.
• Stopping wearing glasses to “strengthen” the eyes.

Some habits can help your eyes feel more comfortable and reduce eye strain, such as the 20-20-20 rule: every 20 minutes of screen time, look at something about 20 feet (6 meters) away for 20 seconds. These habits do not change your degree of myopia.

If you are looking for a long-term alternative to glasses, start with a comprehensive eye exam at Magrabi Health. It will show whether non-surgical options suit you, or whether you may be a candidate for LASIK or Femto-LASIK vision correction.

Before making a decision, you can visit Magrabi’s Refractive Error Correction service page to learn how the condition is assessed and how the right vision correction option is selected.

LASIK for Myopia: When Is It Suitable?

LASIK may be a suitable option for treating myopia in some adults, but it is not determined by vision degree alone. Before the procedure, the doctor examines the eye carefully to make sure the cornea is healthy, vision is stable, and the procedure is suitable and safe for the case.

The assessment usually includes:

• Degree of myopia.
• Vision stability for a suitable period.
• Corneal thickness and shape.
• Presence of severe dry eye.
• Retinal health.
• Keratoconus or suspected corneal weakness.
• Other eye diseases.
• Patient expectations after surgery.

The American Academy of Ophthalmology (AAO) explains that LASIK is used to treat nearsightedness, farsightedness, and astigmatism by reshaping the cornea to improve how light focuses on the retina. It also recommends discussing risks, benefits, dry eye, and future presbyopia before corneal refractive surgery.

When Is LASIK Not Suitable for Myopia?

LASIK is not suitable for every patient with myopia. In some cases, the doctor may recommend postponing the procedure or choosing another option based on eye health.

LASIK may not be suitable if the patient has:

• Unstable vision.
• Insufficient corneal thickness.
• Keratoconus or suspected corneal weakness.
• Severe uncontrolled dry eye.
• Retinal conditions requiring follow-up.
• Cataracts affecting vision.
• Active eye inflammation or disease.
• Unrealistic expectations from surgery.

LASIK should not be treated as a simple cosmetic decision. It is a medical procedure that requires a complete eye assessment to confirm whether it is appropriate for the eye.

Can Myopia Be Treated Permanently?

Yes, myopia can be corrected in different ways, but that does not always mean it is permanently eliminated. Glasses and contact lenses improve vision while they are being used, while LASIK or Femto-LASIK may reduce dependence on them in suitable cases. However, vision may still change later with age or depending on the condition of the eye.

That is why the best option should be selected after a complete eye exam and realistic expectations.

When Should You See an Eye Doctor?

You should see an ophthalmologist if myopia symptoms continue or affect studying, work, driving, or daily activities.

Medical assessment is also important if you notice:

• Repeated blurred distance vision.
• Frequently I need to change glasses.
• Persistent headache or eye strain.
• Difficulty driving at night.
• Sudden flashes of light or black spots.
• Severe myopia.
• Interest in LASIK or Femto-LASIK evaluation.
• Sudden or rapidly worsening vision.

The Ministry of Public Health Qatar emphasizes that vision screening in the early years helps support healthy visual development in children and allows early detection and treatment of visual problems. 

 

Clear vision starts with accurate diagnosis. Book an appointment with Magrabi doctors specialized in vision correction through a phone call or booking form, and begin with a complete assessment to choose the most suitable plan for your case.

Conclusion

Myopia treatment begins with understanding the symptoms, then completing an accurate eye exam to measure the degree of myopia and assess eye health. Prescription glasses or contact lenses may be enough for many patients, while LASIK or Femto-LASIK may be considered when vision is stable and the medical conditions are suitable. Seeing an ophthalmologist helps choose the safest and most appropriate correction method for each case.
