What kind of single vision glasses do you need?

Has your vision changed recently?
Are you not sure whether you need glasses or what kind of glasses you need?
Myopia, Hyperopia or astigmatism

Then you're at the right place.

But first of all

What are single vision glasses?

Single vision lenses can only be used to correct one distance.

Our single vision glasses are there for one specific correction - for example either for reading (close distance) or driving (distant viewing)

Our technology allows a higher image accuracy, even with a high refractive index (which determines how much light is bent, or refracted, when entering the lens). It's all thanks to our aspheric lenses.

What is a vision impairment?

Otherwise known as Ametropia, vision impairment is an ocular disorder in which parallel rays of light fail to come to a focus on the retina

Near-sightedness (also known as: Myopia) is noticed when objects in the distance get fuzzy. They appear blurred and out of focus. The reason for this is because the eyeball does not have the correct length and the cornea is not curved as it should be. This means that the light cannot reach the retina at the optimum distance.

SHORT-SIGHTEDNESS IN A NUTSHELL

Poor, blurred long distance vision

  • PROBLEM: The form of the eyeball is longer and no longer has the correct length in order for the light to hit the front of the retina
  • LENSES: Concave lenses are used in order for the light to reach the back of the retina
  • EYEGLASS PRESCRIPTION: Negative dioptre value with a "sphere" (-Sph)

In this condition, distant objects appear blurred but near objects are clear. One usually has to squint to see things in the distance. Myopia is corrected by concave lenses. These lenses ensure that the light beams coming from objects in the distance are bundled on the retina. This condition is particularly noticeable while driving because Myopia makes it difficult to read or recognise street signs.

Glasses for long-sightedness (Hyperopia)

Far-sightedness, also known as hyperopia, is a condition of the eye in which light is focused behind, instead of on the retina. This causes close objects to be blurry, while far objects may appear normal.This happens because incoming light rays are bundled behind the retina and create a distorted image

LONG-SIGHTEDNESS IN A NUTSHELL

Blurry, unclear vision up-close and at a far distance

  • PROBLEM: The form of the eyeball is too short; the light rays are bundled only once they're behind the retina.
  • LENSES: Convex lenses are used in order for the light to hit the back of the retina
  • PRESCRIPTION: Positive Dioptre value under "sphere" (+Sph)

When you get to 40 or beyond, your eyes begin to lose the ability to focus on close objects. Farsightedness occurs when your eye is too short lengthwise and does not bend light correctly. This causes the eyes to tire very quickly, which is why increased fatigue and headaches can be the first signs of long-sightedness. Convex lenses are used for correction.

Glasses for astigmatism

Astigmatism is a type of refractive error in which the eye does not focus light evenly on the retina. This results in distorted or blurred vision at all distances. The light beams are not bundled at one but at several points, which is why people affected by this, for example see a line instead of a point.

ASTIGMATISM IN A NUTSHELL

General blurred vision, eye and head pain

  • PROBLEM: Instead of the eyeball the cornea is deformed
  • LENSES: With cylindrical lenses / or with soft toric contact lenses
  • PRESCRIPTION: Cyl for cylinder

This disorder is usually caused by genetic factors or occurs after a corneal disease or surgery. This can be corrected, through cylindrical, astigmatic lenses, which correct the different axis positions of the differently distant focal lines.

What kind of glasses you need in case of ametropia (also known as: refractive condition)?

DIOPTER

The sphere that determines the level of ametropia

Diopter (dpt) Descibes the refraction value

The type of glasses you need, depends on the type of ametropia you have.

The degree of ametropia can be divided into three categories: light (up to +/- 3 diopters), medium (+/- 6 diopters) and strong (over +/- 6 diopters).

Negative Diopter value means near-sightedness, while positive means far-sightedness

Is it true that if the degree of the refractive error is high, the lenses will be thick?

Many still suspect that the lens thickness increases with higher dioptry values. Thanks to the technological developments in the production of lenses, thick lenses are a thing of the past.

After the optician has analysed your vision and determined your individual parameters, there are two aspects that can be considered:

1- The smallest possible model should be selected when selecting the frame. Because: the smaller the version, the thinner the lenses.

2- Discuss with your optician whether it is possible in your case to further minimize the thickness of the lenses. Our lenses can be produced with different indices (refractive index) (standard version: Index 1.5).

It is also important to note that our synthetic lenses (CR39) are significantly lighter than mineral glasses. You should also pay attention to the safety aspect, since mineral lenses can splinter and cause severe eye damage in the case of a car accident.

When are single vision glasses no longer effective?

As you get older, the elasticity and refractive power of the ocular lens decreases. Far-sightedness, also known as presbyopia, makes it especially difficult seeing items close to you.

Presbyopia usually occurs beginning at around age 40, when people experience blurred near vision when reading, sewing or working at the computer.

By not having the right glasses you can develop so-called "lazy-eye"

It is assumed that our eyes are accustomed to the support of glasses because we constantly wear them and that the visual defect as a result becomes stronger. This assumption is wrong!

Properly designed glasses, can neither modify nor remove the visual impairments. And various visual exercises, eye training or homeopathic remedies can not eliminate visual disorders. However, children may be able to improve their vision through various visual exercises.

Only surgical intervention using the latest laser technology can minimize or even completely eliminate the defect in adults. A surgery on your cornea, thanks to the latest laser techniques, can improve or even eliminate your defective vision completely.

What kind of single vision glasses do I need?

Our partner optician closest to you will be happy to be of help. Make use of our website specsfactory.co.uk to find out more about our offers and prices and then register.

You can also order your single-vision lenses with coatings. These improve the performance and make the glasses more durable. Super anti-glare, hard coat and clean coat are always included in our prices, and there's a small extra charge for H2 (lotus effect) and iBlue. Learn everything you need to know about our coatings and how you can benefit from them in your everyday life below:

Anti-glare

The polished surface of the spectacle lenses reflects the light falling on it, which can be irritating during a conversation for both participants.
The polished surface of spectacle lenses reflects the light falling on it, which can be irritating during a conversation for both participants. This reflection means that less light penetrates through the glasses, but our super anti-reflective coating helps to improve vision quality and performance.

Hard coating

Thanks to this special surface treatment, spectacle lenses become more resistant and thus more durable. This makes it possible to wear the glasses for sports, other leisure activities or during  manual activity.

The two-sided layer of coating which is applied protects the soft, chemical structure of synthetic lenses and makes them more resistant to scratches. At specsfactory.co.uk the hard coating is also included in every purchase.

Clean-coated varifocal lenses

With clean coating treatment applied, it becomes harder for dust and dirt particles to stick on to the lenses.
This provides an easy to clean surface that prevents stains and hard water marks removes the need for aggressive cleansers.

Super H2

This lotus coating has a greater surface tension and is used as a repellent against any liquid, making cleaning easier.

iBlue

This reflects the blue light levels that you get with modern displays - such as LCD/LED monitors, TVs, smartphones, and tablets - which are harmful to the retina. In addition, your eyes do not tire so quickly and your efficiency increases.
