Getting used to multifocal glasses? Here some tips:
Multifocal, Varifocal, Progressive, Graduated and No-line Bifocal glasses are all the same thing with different names.
Those lenses are used for people who need both distance and close up vision correction.
Multifocal spectacles take time to get used to. In this article I will explain why and give you some tips of how to go thru adaptation time easier.
Once you got your new multifocal glasses put them on and do not come back to your old spectacles.
Any glasses need time to get used to. This is especially true when it comes to progressive lenses. Wear your new glasses full time and give your brain enough time to adopt.
With multifocal glasses it is important to point your head directly at the object you want to look at. If you will try to move your eyes only without moving your head you will be looking thru distorted part of the lens and your vision may become blurry. Good thing to remember is that the clear portion of your lens is a vertical corridor located in the middle of the lens. When you point your head to the object you will keep your eyes in that clear corridor. You should notice that after a while doing this it will become automatic and you will not have to think about it twice.
Adaptation may take a while in fact you should allocate full month time for this process.
If after a month you still did not get used to your new spectacles you have few options. Option number one is to change your lenses from multifocal to bifocal lenses with a line. Many people find them much easier to adapt and use every day, but off course such glasses are less appealing because of that visible line in the lens.
Another option is to get two single vision pairs of spectacles, one pair for near (reading) vision and one for distance.
Whichever way you decide to go, do not forget to try your multifocal glasses for a month before you decide to change.
You can buy multifocal glasses online, but make sure that your optical store provides suitable return policy in case you are not satisfied.

High Index Lenses Explained. Are they worth getting?
Important - High Index Lenses are aimed for people with strong prescription.
The strong prescription needs more bending for the lens than a weaker one, as a result the lens becomes thick.
To avoid thick lenses which may look akward, people use High Index Lenses.
Conventional plastic lens has an index of 1.50. Everything above that is considered a Higher Index Lense. They normally range between 1.57 - 1.70 Index.
Higher Index Lenses imrpove the appearance of your glasses and make them neater, lighter and more enjoyable to wear. They simply look better on your face.
To find out if your prescription is considered a strong one, ask your optometrist or the optical store where you purchase your next new glasses.

Lens Tinting VS Transitional (photochromic) lenses?
First, let me explain what both of these options mean:
Advantage: Great selection of colors, You can choose percentage of tint darkness, Can be used and as good as sunglasses, Much cheaper then transitional lenses
1. Lens tinting is when the lens is permanently tinted with a colour and percentage of your choice. You can select an 80% grey tint and
your glasses will look like sunglasses or you can go with lighter version and different color to suit your style.
Disadvantage: Tinting is permanent, you cannot undo it.
2. Transitional or also known as photochromic lenses become dark only when they are exposed to sun light. Usually they don't offer much color variations, normally grey or amber limits your choice. It takes time for such lenses to become dark when you go outside or clear again once you are inside. Normally full transition time is between 7-15 mins depending on a lens.
Advantage: Can use such glasses both inside and outside.
Disadvantage: Small color selection, Transition takes time ( which can be a bit annoying), More expensive, Although such
lenses become dark when you are outside, they are not as dark as your normal sunglasses.
