Trifocal lenses improve distant, intermediate, and nearby sight issues. You might be aware of the far and near sight issues and their relevant corrections. But the intermediate vision, too, is essential for most of our everyday tasks. To cater to all three, trifocal, as the name suggests, consists of three separate lenses that re-establish a complete vision range.
Ideally, trifocal lenses work for people over the age of forty who are suffering from existing conditions or have developed presbyopia due to age. They are made up of an anti-reflective layer to promote the comfort of thoroughly clear eyesight. The coating provides better vision in low-light situations.
Whether you are finding a good solution for yourself or a senior loved one, a local eye doctor will be able to help you understand if a trifocal lens is a suitable option.
Advantages of Trifocal Lenses
These multi-purpose lenses have a range of benefits:
- These are three-in-one correction lenses saving you from the hassle of managing multiple glasses.
- Enable a broader viewing area in case of nearer vision. That makes it easier to use a screen or read with reduced strain on the eyes in case of dimmed surround lights.
- From the beginning, you will experience enhanced visibility and brightness in the colors around you.
- Trifocal glasses offer you the ability to see adequately in all kinds of lighting conditions, including dim lighting, bright lights, low light, and even daylight.
- Another significant aspect is that you will endure fewer glares from bright lights, which will make driving at night easier for a lot of people.
Disadvantages of Trifocal Lens
As is the usual practice, here I am presenting the other side of the story as well for better perception:
- Since trifocal lenses correct multiple sight problems simultaneously, you might experience some visibility issues when seeing through another section of your glasses.
- The trifocal lens within the case of cataract IOL might cause reactions such as blurred sight or intolerable glare because of the presence of the implant.
- Unlike progressive lenses, there is no possibility of customizing these glasses.
How to use them?
It is essential to note that the trifocal lenses are easy to use. Below are some of the measures you can take to make the transition convenient:
- Learn the proper technique of using your new glasses from your optometrist and make sure they fit you well.
- They should be well adjusted on your nose to avoid slipping, and for you see through them appropriately.
- Always ensure that you continue looking in front and not downwards when walking. That will avoid vision distortions due to the glasses.
- When reading something, it should be held at a convenient distance for you to be able to read it properly without much strain.
Can anyone use trifocal glasses?
Although they can overcome a variety of visibility issues, trifocal do have their limitations. In patients with Age-Related Macular Degeneration (AMD), advanced glaucoma, diabetes, and cataracts, the trifocal lenses are not a suitable solution.
The ideal candidates for trifocal lenses are people over forty who are suffering from presbyopia that prompts them to need to change or begin their eyeglass prescriptions. Trifocal glasses can restore enhanced visibility in all ranges and can be chosen as an alternative to avoid correction surgeries.
If so far, you have been able to figure out that you need trifocal glasses, you can go a step further by visiting an eye doctor in your local area. They will be able to understand your prevalent eye ailments and then prescribe the most suitable lens options for you. Remember, trifocal glasses and contacts ensure a close-up, intermediate, and faraway view.
