Have your eyes been a matter of trouble for you lately? Do you feel like you are not able to see objects clearly?
Relax! Eye problems are common and sometimes reversible as well by using glasses. But if you keep pushing that long-overdue eye checkup, the situation will get even worse with time.
If you spend a major part of your day working on a laptop or digital screen, you must wear blue light glasses. These lenses shield your eyes from the harmful blue light that is capable of damaging your retinal cells over time.
Even if it is not you who gets to decide the type of glasses you will need to use, you would want to know what you are in for. Won’t you? If you are with us so far, you probably do.
The entire mystery of prescription glasses can be broken down into two categories: single-vision glasses and multifocal glasses.
Single-vision glasses
Single-vision lenses are used to fix either short-sightedness or long-sightedness. These are the most common type of glasses and that is what makes them least expensive as well.
People with the following eye problems may need to wear single-vision lenses:
Presbyopia
Contrary to myopia, presbyopia refers to the insufficiency of the eyes to see things up close. This condition is normal to occur as you approach your mid-40s.
Eye problems can arise due to so many factors including age. As we get older, our near vision starts to diminish which is why we need reading glasses to see the nearby objects. These glasses can be used even if you haven’t consulted your optician.
Myopia
If you struggle to see objects clearly unless they are placed close to your eyes, chances are that you have myopia. It is a common refractive error that is found in children as well as young adults. The vision loss progresses gradually with time and you may feel symptoms like eye strain, fatigue, and headache along the way.
Multifocal glasses
Multifocal lenses are prescribed to fix both distance and the near vision. You don’t have to carry a different pair of glasses for reading only. With multifocal lenses, you can have a one-stop solution to both the problems.
Let’s get a deeper insight into the different types of multifocal glasses:
Bifocal glasses
As the name suggests, these glasses have two lens powers in one. Where a smaller segment in the lower half of the lens is designed to improve your near vision, the rest of the lens focuses on your distance vision.
If you use bifocal glasses, you look up when you are looking at the objects far away and look down when reading or focusing on objects that are close to you.
Trifocal lenses
Where bifocal lenses correct two types of vision problems, trifocals also help towards better intermediate vision. These glasses have two lines on their lenses to segregate them into three parts and serve all your vision needs.
The middle part of the lens is specifically designed to work on your intermediate vision when you are looking at things that are just a few feet away from you.
Varifocal glasses
Varifocal lens serves the same purpose as bifocals or trifocals with the only difference being its smooth transition lines. Although it is an impressive adjustment to avoid the dividing lines, the focal areas of the lens diminishes as more space is taken up by the transitional areas.
It usually takes longer for people to get used to varifocal glasses as opposed to other lenses due to different lens powers. At first, you may even feel blurry vision but you must always use your varifocals if you want to adjust to them fast.
What’s next?
There is nothing much you can do about the types of lens your optician would recommend. But, things are not entirely out of your control. There are certain aspects of your glasses that you can control to rock even in your new look.
You can choose stylish frames that go with your style and fit your face or you can choose to buy light weight lenses that don’t feel heavy on your face. Price is a huge factor when you are buying eyeglasses. But remember, expensive lenses do not guarantee high quality. You can look just as fine in affordable glasses as well.
