By choosing the right lenses you can get the maximum benefit from your glasses and optimally improve your vision. You can base your choice on your visual needs, on the lenses you are used to, or on the price.

In order to match your lenses as well as possible to your wishes, Optiek Ninon has divided the prescription lenses into different packages. Based on your viewing behavior you will receive advice on which glasses suit you best.

Single vision lenses

Single vision lenses have the same prescription over the entire lenses. Usually these types of lenses are suitable for people who are either near or farsighted, and who only need glasses for driving, reading or computer work.

How do single glasses work?
If you only need glasses for one type of vision abnormality, your optician may prescribe single vision lenses.

You may need different glasses for different activities, such as glasses for far away when driving, and other glasses for close by when reading.

People up to forty years usually go for this type of glasses because they probably only have one prescription.

Your optician can advise you on the type of lenses that best suit your needs.

Bifocal glasses

With bifocal lenses you have a sharp view both close by and far away. The reading part is a clearly visible area in the lower segment of the lenses. For people who cannot get used to varifocal glasses, bifocal glasses are a suitable alternative.

How do Bifocal Glasses Work?
Bifocal lenses combine all your visual needs into one pair of glasses and can be an easier solution than two single-pair glasses.

For example, if you work in an office, you may want a mid-range view at the top of the glass for meetings or presentations, and a close-up view of the area through which you look at your screen.

Multifocal glasses

What are multifocal lenses?
Multifocal or Varifocal lenses are sharpened to multiple strengths and therefore you can use them both as reading glasses and regular glasses. The precursor of these glasses are the bifocal glasses: in these glasses the reading area is clearly recognizable by the ground surface. This surface allows you to read well, while the rest of the glasses is to look “normal”. In the meantime, the technology is already further, and the transition of strength is gradual, so that you can look well into the distance through the top and read with the bottom.

The pros and cons
Because the lens is made from multiple prescriptions, you will often have to get used to looking through the glass in a certain way to see something sharp. This may be somewhat uncomfortable in the beginning, but you get used faster than you think. The lenses also sometimes distort somewhat, although nowadays very good multifocal lenses are available that minimize distortion. The advantages: you no longer must switch between reading glasses and normal glasses and once you are used to it, you have a clear view of all distances, without having to try.
