Hi guys,
Remember last week I was talking about presbyopia. That’s where you begin to need help with reading round about the age of 40. I thought today I’d tell you about the various ways that this is corrected.
Prescription reading glasses.
These are single vision glasses that have been made up with your reading prescription. The problem you might notice with these is that when you look up and across a room, things in the distance will be a wee bit blurred. It really depends on your occupation and lifestyle whether single vision is the best option for you. If you don’t move around too much, or are looking at a computer screen all day these might be the best option for you.
Bifocals
You’ve maybe seen these. The lenses have a wee line about a third up from the bottom rim. Above the line is your distance prescription and below it is the reading prescription. This alleviates the problem mentioned above. Bifocals can take a wee bit of getting used to, but after a few days you’ll have no problems.
If you are in front of a screen all day though, you might be better with reading specs.
Some people don’t like the fact that everyone can see the line.
Varifocals
These lenses look the same as single vision lenses, so are cosmetically better than bifocals. There are different zones within the lens. The top part is for distance vision, and like bifocals the lower part of the lens is for reading but in between the lens is graded for intermediate vision. This means that you can see at all distances.
These can also take a bit of getting used to. The best advice I can give you is decide before you pick them up that you will be able to use them. Positive mental attitude. It works wonders.
I wear Freeform varifocals. These are the latest technology available in varifocals.
It is important when choosing what lens is going to be best for you that you tell us about your working environment and what hobbies you do. We’ll make sure that you get the best lens for your needs.
Next week I’m going to talk about high index lenses so do look in.
Have a great weekend.
Carla
