What Are Progressive Lenses?
Progressive lenses have grown in popularity and are one of the most common solutions to treat vision loss that occurs with age or presbyopia. This eye condition occurs when the eye loses some of its flexibility and ability to adjust to clear seeing objects at different distances. Presbyopia often occurs among adults who are over age 40 and is very easy to correct with a proper and prompt diagnosis.
Progressive lenses are often used to correct this eye condition. Progressive lenses are a modern alternative to bifocal glasses, which provides two prescriptions in a single set of glasses. Bifocal glasses are a better solution than carrying around multiple pairs of glasses. Progressive lenses were developed to resolve some of those common issues and to provide better aesthetics. Progressive lenses provide a smooth transition and can accommodate up to three prescriptions and are a replacement for both bifocals and trifocals.
Adjust the nose pad
The height of the nose pad is adjusted by first holding the glasses with one hand and holding the nose pad with pliers with the other. Then the pliers are lifted up and the nose pad is moved down until the glasses are in the correct position on the face. The asymmetrical adjustment method is to first hold the frame of the eyeglasses with one hand, the other hand clamps the nasal plate with pliers. Then twist it in the direction of the correct tray position so that the surface of the tray is in contact with the two sides of the nose. Wrap one side of the lens of the glasses to be operated with a cloth first to prevent the screwdriver from slipping and scraping the lens during the operation. Don't scratch your glasses by adjusting your nose pad.
How to choose frames?
Of course, the best way is to try it on many times. The visual effect is more direct and reliable than trying on. Spend more time and you can find your own style suitable for you.
In addition, where comfort and aesthetics permit, choose the size as large as possible so that the view will be larger. However, there are some optometric parameters that limit the selection of frames. For example, if the pupil distance is very small, choose a size that is too large is not suitable. Try not to choose the product with spray paint on the surface, because durable time is shorter.
You should pay special attention to that TR, plastic steel, stainless steel, wood, β titanium glasses temple may not be adjusted. When trying on, it should be noted that the weight of the lens has not been added to the trying frame, to avoid the problem of discomfort (such as an easy slip of the frame) found after the preparation.
Glasses Size - Lens Height
Lens height is the length between the top edge of a lens and the bottom edge of that lens. Lens height is the distance between the lowest point of the lens and the top of the frame above it. This number may be influenced by the style of your glasses.
Different styles of glasses
If the style of new glasses is different from the old glasses, the angles of the glasses are also different. So the new glasses will cause visual differences. The symptoms of dizziness after wearing the new glasses will occur after a short period of time. If you adapt, you should be able to return to normal.
In order to avoid discomfort in wearing glasses due to inaccurate optometry, experts suggest that myopia should choose a professional eye hospital for medical optometry. When the glasses are damaged, they should be replaced in time to avoid injury to the eyes.
What are the benefits of the TR-90?
Impact resistance is more than 2 times of nylon material, in order to effectively prevent the damage to the eyes caused by impact in the movement. It has high-temperature resistance. It's very elastic, and it doesn't deform.The use of thermoplastic materials in these frames provides pretty strength due to their flexible characteristics. It is not easy to deform and change color, making it wear for a longer time. Having no release of chemical residues, it is in line with the European requirements for food-grade materials. The weight is less than half of the weight of the plate frame, 85% of nylon material, reducing the burden of nose bridge, ears, and making wearing more comfortable.
