Progressive Lenses help a person in his or her distant and near vision. These are more beneficial than the bifocals from the perspective that you need not worry about radical changes in vision that people suffer while shifting from looking through one part of the lens to the other. These lenses, on the contrary, offer a seamless transition. The lenses gradually magnify towards the bottom. However, with all that being said, you need to consider the following things to help you make the buying decision.
When choosing the ideal frame for your lenses, frame size becomes an important consideration. Progressive Lenses allow the user to see in all directions and distances. Thus, it is important that the entire range of vision can fit within the frame.
Frames with shorter lens size usually do not fit progressive lenses. This works for frames with larger lens size. Further, people wearing these lenses should avoid aviators and car-eyes. Both cut off the bottom portion of your vision. It may cause a loss of reading vision.
Consider Fitting Errors
Issues with progressive Lensesusually come from fitting errors. As the glass returns from the lab, the optician calls the prescription-holder in the retailing unit. The person tries the lenses on to conduct a final adjustment check. He or she must make sure these fit correctly to the eye’s shape of the patient and serve the requirement.
Fitting errors may also come from the doctor’s prescription if it does not offer details on the lens. You will suffer from vision problems while reading books or walking downstairs. Adjustment to pupils is also essential. The optician takes the measurement of Pupillary Distance and Fitting Height. These two ensure the adaptation.
Pupillary Distance is the gap between the pupils. Fitting Height is the measurement from the pupil’s center to the lens’s bottom for each eye.
It is important that you maintain the natural posture when the optician places the glasses on your face. Tilting your head at an angle you usually do not slant in may bring errors in the Fitting Height measurement.
Consider the Time Factor for Adapting the Lens
Like others, Progressive Lenses also take time to adjust to the eyes of the user. People usually take their time before getting used to this particular type of eyewear. It depends on the capability to adapt of the person concerned.
Avoid Smaller Frames
Smaller lenses, the doctor worries, will not offer you the proper coverage for all three fields of view. Shorter lenses inhibits near vision. You will not be able to see the objects closer to your face. Ophthalmologists recommend short-corridor lenses for people who prefer smaller frames.
Looking Through the Correct Part of The Lens is Vital
While using these lenses, look through the top position while driving. Looking through the middle zone will help you see better using a computer. The optician will ask you to see through the bottom part of the lens while reading books
Doctors will warn you about the importance of looking through the correct position; else, your eyes might strain themselves.
Progressive Lenses Cost More. Yet, They Can Assure You of Customization
Standard lenses are indeed more affordable than their developed varieties. Yet, the opticians can make progressive ones more tailored to your needs. This is worth the extra cost.
Consider The Best Fit
Try the progressive glasses with an eye doctor to ensure the best fit. Depending on working conditions, you may need different types of progressive lenses. Eye doctors will usually recommend lenses with a broader midsection to office workers. It helps, as discussed earlier, to look at the computer.
The Final Talk
Finally, we ask you to consider some drawbacks that may hinder you from using progressive glasses.
In the first place, these glasses have a learning curve. They do not have a visible line to guide you; thus, you must train yourself to look out of the correct portion of the lens for the tasks ahead.
Take care to look through the top portion of the lens while being outside, either walking or driving. If you walk upstairs and look down through the lower part of the lens, your feet may appear larger than they are and can cause accidents.
These lenses can also cause marginal distortion when moving your eyes from side to side. For the first few days, you may feel off-balance or nauseous from looking through the wrong section of the lens.
And, finally the cost. Progressive lenses are significantly more expensive than single or multi-focal glasses. It is because of the extra time that goes into creating a lens with multiple areas of vision and no lines.
