This is the most common type of contact lens that corrects refractive errors.

Made from flexible and oxygen-permeable plastic material to safe for the cornea.

Soft contact lens materials are increasingly being improved to have higher oxygen permeability, and now, Silicone Hydrogel is the most advanced material.

Advantage:

– Time to get used to contact lens quickly, bring comfortable feeling on the eyes.

– Variety of lenscolors: transparent, lightly pigmented or dark pigmented

– Variety of lens replacement: daily, two weekly, monthly, quarterly, conventional

– Variety of contact lens design: single, multifocal.

Soft contact lenses are now widely used and easy to buy. However, to ensure the health of your eyes, choose appropriate and safe contact lenses dispenser.

Come to Minh Anh Eye Clinic to be consulted by a team of experts and choose the most suitable and safe contact lenses for your eyes.

What is myopia and the status of myopia?

Myopia is a refractive error caused by an elongation of the eyeball axis or an abnormal curvature of the cornea resulting in an image of objects formed in front of the retina. People who have myopia will see blurred vision in the distance than near, if high myopia can see blurred both far and near.

Myopia is the most common eye abnormality. In Vietnam, the rate of myopia in students is estimated at 30-40%.

It is estimated that by 2050, the rate of myopia in the world will be nearly 50%, this is an alarming number and a great economic burden for society.

Risk factors for myopia progression

–        Heredity: The risk of developing myopia is higher in children of myopic parents.

–        Time of early onset of myopia.

–        Work at near distance.

 Why myopia progression is a concern?

 Myopia progression associated with an elongated eyeball increases the risk of serious vision-threatening complications such as:

 –        Glaucoma

 –        Cataracts

 –        Degeneration, retinal detachment

 –        Macular Hole

 –        Choroidal neovascularization

 Different approaches to control myopia progression

 –        Orthokeratology (Ortho-K) contact lenses: change the corneal curvature during sleep (return to normal when not using contact lenses), is a safe, highly effective method in limiting the progression of myopia, patient do not need to wear glasses. However, the cleaning and maintenance requirements are more complicated.

–        Multifocal soft contact lenses: as effective as Ortho-K.

–        Low dose Atropin: More experimental studies are needed, as side effects include photosensitivity and glare up close.

–        Bifocal/multifocal glasses.

–        Increase outdoor activities.

 Take your child to the eye doctor right away when there are risk factors or suspicious symptoms such as squint, come closer to see, need to change glasses due to increasing myopia in a short time. Come to Minh Anh Eye Clinic for advice on methods of management progressive myopia control.

TODAY WE LEARN HOW TO REMOVE AND STORE CONTACT LENSES!!!

Using contact lenses requires strict hygiene.

 Cut your nails short, don’t let them sharpen, and don’t paint your nails.

 Wear contact lenses in a clean place (not in the bathroom)

 Open one lens case at a time; after wearing one lens, open the other lens case to get the second contact lens to wear (this step is to avoid wearing the wrong two eyes)

 NOTE: “DO NOT USE TAP WATER TO WASH CONTACT LENSES, MUST USE CONTACT LENS SOLUTION!!!” 

WEAR CONTACT LENSES BEFORE GOING TO SLEEP AT NIGHT

1. Wash and dry your hands. Open one side of the contact lenses case, take the contact lenses and put them in the palm of your hand.
2. Pour contact lens solution on the contact lenses. Use your index finger to clean the lens from the center of the contact lenses to the edge (360 degrees) clean the contact lenses twice, at least 1 minute each time.
3. Put the contact lenses face up on the index finger. Put a single drop of artificial tear into the lens.

4.Use the index finger and thumb of the other hand to widen your eyes.

5.Looking in the mirror, put the contact lenses on the black part of the eye

6. Slowly remove your hands from your eyes and blink.

– Contact lenses are worn correctly when covering the other eye, the worn eye can be seen clearly.

– If the contact lenses are misaligned, find the contact lenses and use the tool to take them out and put them back on.

 – Do the same with the other eye.

 – After wearing it, wash the contact lenses case with hard glass cleaner and turn upside down to air dry.

Clean the contact lenses case and lens remover tool with a separate toothbrush weekly with soap and water. MUST DRY YOUR LENS CASE BEFORE REUSING.

How to remove contact lenses (when waking up)?

• Wash and dry your hands with your eyes open. Check if the lenses are on the black part of your eyes.
• Put 1-2 drops of tears into the eye, blink several times, put your index finger on the lower eyelid and put up the lower edge on the contact lenses until the contact lenses move quickly over the eyes.
• Lens removal device: gently place the lens removal device on the contact lenses (1/3 lower of the lens) and gently remove it. Slide the lens gently out of the tool.
• OR: Press the upper and lower eyelids with 2 index fingers. Align the bottom edge of the contact lenses to the lower lashes and the top edge to the top lashes.
• Wash the contact lenses and put them in the corresponding lens case.
• Put them on their case and fill them with solution.
• Change the solution every day.

IF THE LENS FALLS TO THE GROUND:

 –        When the contact lenses are upside down, use the device to get the contact lenses

 –        When the contact lenses are facing up, we take two fingers to hold the same position of the contact lenses (hold one edge of it).

 –        Rinse before cleaning to avoid scratching the contact lenses.

1. What is amblyopia?

Lazy eye (amblyopia) is reduced vision in one eye caused by abnormal visual development early in life. 

 Usually, amblyopia is the result of eye diseases such as high refractive error or anisometropia, strabismus, or other abnormalities that interfere with vision: ptosis, congenital cataracts,… Children at this time cannot use one or both eyes normally, then the visual function of the brain is not “learned” correctly and as a result, the ability to see is reduced leading to amblyopia.

1. How to recognize a child may have amblyopia? 

–        Blur vision

–        One eye crossed inside/outside (strabismus)

–        Eye movements are not in the right direction, not well coordinated

–        Poor depth perception

–       Squint the eyes to see

–        Tilt, turn your head to look

–        Cry, avoid when covering one eye

–        Abnormal eye appearance

–        Poor academic results, loss of concentration when reading books

1. Is there any method to prevent and treat amblyopia?

 Treatment according to the cause: If amblyopia is caused by strabismus, congenital cataract or ptosis, …, the doctor will consider many factors that are suitable for each child’s condition to eliminate the causes amblyopia by surgery at appropriate stages and times. In the case of amblyopia due to refractive errors (myopia, hyperopia, astigmatism, anisometropia), the child will be prescribed the correct glasses.

Make the eyes with amblyopia work: Better eye patch or atropine treatment helps the amblyopia eye learn to see.

Treatment of problems related to binocular vision

Finally, regular eye exams for children are the only way to detect and treat children with amblyopia in an early stage.
