People who have vision problems would search for lenses to see things better and clearly. If you are also one of those, you might have already searched for a suitable lens and probably heard of “PAL”. But, what does PAL mean on eye prescription, and how can it help you?
Check this article to know more about PAL, its types, and which one is suitable for your specific problem!
What Does PAL Mean On Eye Prescription?
PALs stand for Progressive Addition Lenses, and they are made to help people see things better and clearer at different distances. These types come with designs that would be suitable for those who have reduced accommodative strength.
People often choose bifocals when they have problems with their eyesight. But some people might prefer PALs because they can see things from different distances. Then, their eyesight is better in both close-up and faraway things.
To temporarily fix the problems of farsightedness and nearsightedness, you would see many people wearing corrective glasses to see things easier. This solution is nothing new for us as we all see one person wearing these glasses, especially the older ones.
In this case, PALs play the same roles as corrective glasses, but people have gradually switched to this type due to their convenience. It is also a good choice for those who do not like to wear glasses. There are three main sections of PALs, and they provide different solutions for particular problems.
The PALs’ lower section helps you to see things sharper at close distances, while the upper section will provide you with the strength to see clearly at longer distances. There is also a middle section for you to see things better at middle or intermediate distances.
Most people in the age of 35 or more might have problems because of different factors, and this is why older people are the ones who need them more. Besides, as the new generations use smart devices like phones and laptops more, this solution is more and more preferable.
Not just helping people with vision problems, some certain types can also help them prevent growing issues or prevent them from becoming more serious. The next section will list the most common types that you might need or care about.
