Myopia

Commonly known as nearsightedness or short-sightedness, myopia is a vision problem that causes distant objects to appear blurred, while nearby objects can be seen clearly.

What causes nearsightedness?

Nearsightedness usually occurs when the eyeball is slightly too long. This means that light does not focus properly on the light-sensitive tissue (retina) at the back of your eye. Instead, the light rays focus just in front of the retina, causing distant objects to appear blurred. Myopia often runs in families, but it has also been linked to focusing on close-up objects, such as books and computers, for long periods of time.

How do I know if I am nearsighted?

Signs that you may be nearsighted include:

Difficulty reading street signs and car number plates
Trouble seeing words on a whiteboard or television screen clearly
Squinting to see better
Frequent headaches or tired eyes

How can nearsightedness be corrected?

In most cases, nearsightedness can be corrected effectively with concave single vision lenses. These refocus the light correctly on the retina. If you are nearsighted, your prescription will be a negative number. The higher the number, the stronger your lenses.

If you are concerned about your vision or noticed that it has changed, contact your nearest Hoya Vision optician.

Hyperopia

Commonly known as farsightedness or long-sightedness, hyperopia is a vision problem that causes nearby objects to appear blurred, while distant objects can be seen clearly.

What causes farsightedness?

Farsightedness usually occurs when the eyeball is slightly too short. This means that light does not focus properly on the light-sensitive tissue (retina) at the back of your eye. Instead, the light rays focus behind the retina, causing nearby objects to appear blurred. Hyperopia often runs in families, but it is also linked to age and certain medical conditions such as diabetes. Age-related farsightedness is known as presbyopia.

How do I know if I am farsighted?

Signs that you may be farsighted include:

Difficulty focusing on objects nearby
Squinting to see clearly
Frequent headaches
Eye fatigue when reading, writing or using digital devices

How can farsightedness be corrected?

In most cases, farsightedness can be corrected effectively with convex single vision lenses. These refocus the light correctly on the retina. If you are farsighted, your prescription will be a positive number. The higher the number, the stronger your lenses. If you are concerned about your vision or notice that it has changed, contact your nearest Hoya Vision optician.

Presbyopia

Presbyopia is a vision problem that causes nearby objects to appear blurred, while distant objects can be seen clearly.

What causes presbyopia?

Also known as age-related farsightedness, presbyopia usually affects people over the age of 40. Presbyopia is a gradual thickening and hardening of the lens of your eye. As the lens loses its elasticity, the ability to focus on nearby objects declines. Presbyopia can be accompanied by other vision problems such as nearsightedness, farsightedness and astigmatism.

How do I know if I am presbyopic?

Signs that you may be presbyopic include:

Increasing difficulty focusing on nearby objects
Holding books, newspapers, digital devices and so on at arms length in order to read them properly
Frequent headaches and eye fatigue

How can presbyopia be corrected?

In most cases, presbyopia can be corrected effectively with progressive lenses. These contain a plus prescription for near vision at the bottom of the lens and a prescription for distance vision at the top of the lens. If you are concerned about your vision or noticed that it has changed, contact your nearest Hoya Vision optician.

Astigmatism

Astigmatism is a common eyesight problem that causes blurred or distorted vision.

What causes astigmatism?

Astigmatism occurs when the transparent layer of tissue (cornea) at the front of your eye is not perfectly curved. This irregular curve means that light rays entering your eye focus in two different places on the light-sensitive tissue (retina) at the back of your eye. This creates a blurred image. Astigmatism is usually present at birth and may accompany other vision problems such as nearsightedness and farsightedness.

How do I know if I have astigmatism?

Signs that you may have astigmatism include:

Blurred or distorted vision up close and at a distance
Trouble distinguishing between vertical, horizontal and oblique shapes
Confusing letters such as H for N or C for O
Headaches and eye strain

How can astigmatism be corrected?

In most cases, astigmatism can be corrected effectively with toric lenses. These are specially designed and shaped to compensate for the irregular curve of the cornea that causes astigmatism. If you are concerned about your vision or notice that it has changed, contact your nearest Hoya Vision optician.

Tips en adviezen

1. Gebruik altijd uw beide handen om de bril op of af te zetten.
2. Let er bij het schoonmaken van het montuur goed op dat de
glazen niet beschadigen. Leg uw bril nooit op de glazen neer,
want bij het verschuiven van uw bril kunnen krassen ontstaan.
3. Moderne monturen zijn van sterke materialen gemaakt. Toch
zijn ze vaak kwetsbaar. Een montuur is immers zo licht mogelijk
gemaakt om u maximaal comfort te bieden. Gebruik
daarom een goed passend, stevig briletui. Dit biedt de beste
bescherming.
4. Het is altijd verstandig om de bril bij de glazen vast te houden
en niet bij de veren. Bij het reinigen van het glas dient u eerst
de harde stofdeeltjes, die krassen kunnen veroorzaken, van
de bril te spoelen door deze onder stromend, handwarm
water te houden. Het montuur kunt u vervolgens reinigen
met lauwwarm water, eventueel met een zachte zeep (zonder
citroenzuur).
5. Droog uw bril met een schone zachte doek af. Het beste
kunt u daarvoor een zachte doek gebruiken die zonder
wasverzachter is gewassen. Wasverzachters kunnen namelijk
een wazige zweem op uw glazen achterlaten.
6. Papieren zakdoekjes, keukenrol en papieren brillendoekjes
zijn taboe! Deze bevatten vaak houtvezels die uw glazen
blijvend kunnen beschadigen.
7. Agressieve stoffen kunnen uw brillenglazen ook blijvend beschadigen.
Voorkom daarom contact met aceton, parfum, haarspray,
huishoudelijke schoonmaakmiddelen, citroenzuur enz.
8. Leg uw bril niet op of in het dashbord van uw auto en stel de
bril niet bloot aan hoge temperaturen of grote temperatuurverschillen
(sauna).
9. Wanneer u de bril ergens tegenaan gestoten hebt, kan het
zijn dat deze niet helemaal lekker zit. De bril moet dan worden
bijgesteld. U kunt dit beter niet zelf doen, maar kom gerust
langs in onze winkel, zodat wij de pasvorm met de juiste
instrumenten weer kunnen herstellen.
10. Wij streven naar optimale tevredenheid. Is er iets niet naar
tevredenheid of verwachting, vertel het ons dan alstublieft.
Wij kunnen dan samen naar een oplossing zoeken.
