From the beginning of progressive eyeglasses and to its current popularity
, there have been numerous people with presbyopia who are praising these advanced glasses. But in fact, there are still some other aspects of these reading glasses. It is widely said that prescription eyeglasses will not cause image jump and other side effects. This saying is only partially right. The truth is that progressive eyeglasses also require new users to experience a period of adaption. During this process, visual dizziness and even headache may occur. The reason is that a gradient of lens powers has been incorporated in a single lens. Presbyopic patients who have been using bifocals or trifocals can hardly get quickly used to progressive lenses. This is only one negative point of progressive glasses. Discount progressive eyeglasses help us know another point.
It is also true that progressive eyeglasses are made with advanced lenses with a power addition. Well, it is really not an easy task to include an array of lens powers into a sole lens. But this is the true case in progressive lenses, just as the name indicates. It is acceptable to suppose that these lenses involve relatively more complex design and development. Those who first created progressive lenses and used them were absolutely worthy of our applause. The idea behind those progressive lenses is so different from bifocal and trifocal lenses that more effects are needed to fulfill it. This suggests more tasks at the side of lens manufacturers. Discount progressive eyeglasses are a natural choice because these glasses will certainly charge a higher price than other spectacles.
The necessity for choosing discount progressive eyeglasses is also based on another factor that modern small eyeglass frames make it harder to insert powerful progressive lenses. Proficient skills are required to manage lens fitting and insertion. This will further bring up the average price of progressive eyeglasses.
C: Discount progressive eyeglasses are a necessity for presbyopic patients. The reason is that these glasses enabled by complex lens design and finished by more efforts will certainly charge a higher average price.
