Some people need different prescriptions or power depending on the distance of the objects. For example, if the short-sightedness is -3.00, they need that power glass to view far objects. However, they can see near objects very clearly even without wearing glasses. They need a higher power to see distant objects and a lower power to see near objects.
Multifocal glasses aid in multiple focus vision points. It gives the wearer adequate power to see things from different distances more clearly.
What are multifocal glasses?
Technically called progressive glasses, multifocal lenses are eyeglasses that combine multiple prescriptions within a single lens in vision zones, as opposed to single lenses that only have a single distance zone, which most people wear. Some opticians can serve you with same day multifocal glasses at a slightly higher price.
Multifocal glasses consist of different power or prescriptions within a single pair of lenses. It helps people see far clearly, such as while driving or watching a movie and near objects, such as when reading text messages on a mobile phone. They have multiple prescriptions that cater to astigmatism and short-sightedness. People usually use it after they reach the age of 40.
People need multifocal glasses if they have Presbyopia. It is a natural part of aging. It becomes noticeable around 40 and gradually worsens as you age. A good indication of Presbyopia is when you must hold the reading materials far away from you for a clearer vision. An eye test can confirm the onset of Presbyopia. Some people might consider surgery.
Presbyopia is a condition whereby you gradually lose your ability to see near objects. This loss of focus causes trouble when you shift your vision from a distance to a nearby object. People who suffer from Presbyopia may find using multifocal lenses more convenient as they aid with both distant and near vision in a single lens.
However if you are considering laser eye surgery and are wondering whether or not you are likely to be eligible for it, it is highly recommended to speak with experienced doctors like the ones at Quality Eye Surgery in Vancouver about all of your treatment options. They can assess your condition and help guide you towards an informed decision about the eye laser surgery that is right for you.
If you use two or multiple glasses for your day-to-day functioning, such as one pair for driving and another for reading, it is more convenient to use multifocal glasses. It combines numerous prescriptions into one. That way, swapping between different glasses frequently while working is not necessary. That can be a bit inconvenient.
You must wear your progressive lenses or multifocal glasses every day, at least initially, when you start wearing them. Though you may feel some uneasiness initially, stick to it. Wearing it every day will get you up to speed within no time. Wear them for about three weeks; after you have adjusted to them, you can use them only as required.
If something is bothering you or you find yourself taking off your glasses often, then chances are that you need multifocal glasses. Or you may be holding your phone away to read the text message. Some people tilt their heads sideways or up and down to find the best vision. Or they take their glasses off to look at people or see distant things.
If you can relate to any of the above uncomfortable experiences, you need multifocal glasses for comfort. All the above indicate that your current eyeglass is not enough and that you may require multifocal glasses. Therefore, comfort is one of the main reasons people choose them.
What to look for
The ideal multifocal lens will adapt to your vision situations automatically. It provides seamless vision, whether from a screen or at a distance or a printed material. The best lenses are the ones with the most minor distortion.
Try to see how wide and far you can see without disruption while moving your head. A good multifocal lens will have less blurriness. For brand new glasses, there are usually some areas of blur at the border of the lenses. Hence, to avoid it, you may need to move your head more to see clearly in the periphery.
Types of multifocal lenses
Besides checking out the vision, you need to know the types of multifocal lenses, which hopefully should help you in your purchase decision. There are several multifocal lenses ranging from the basic to the most advanced technology, each with a different price. But the essential thing you need to know is what frame size to use, how frequently you would be using it, and your current budget.
Basic multifocal glasses perform better in big frames, whereas a small frame is more suitable for high-performance glasses as modern technology adapts well to smaller frames. If you use multiple focal lenses daily, you may want to consider trying out high-performance glasses. If budget is your concern, a basic lens may be the most suitable. If you are experienced and have worn multifocal lenses before, then a higher quality multifocal glass may improve your vision.
