What is a progressive lens?

A progressive lens is a lens whose upper sides are used to see far, and the lower side is used to see near. The distance from the fixed distance power above the lens to the near power fixed below the lens does not change suddenly, but a gradual transition between the two through the gradual change in refractive power.

Standard progressive lenses are multifocal lenses with three observation areas, farsightedness, intermediate vision, and nearsightedness. Unlike bifocals, there are no visible lines between each viewing area. They have a seamless, invisible design, where the optical power changes 'gradually' throughout the lens. Many people confuse 'bifocal' or 'trifocal' with 'progressive' but remember that bifocals and trifocals have visible lines in the lens, while progressive lenses do not. Because progressive lenses have no lines in the lens, they are more popular multifocal lenses than bifocal lenses. However, is progressive lens good for eyes?


How to choose browline frames?

From the perspective of aesthetics, the factors that need to be considered when choosing a suitable pair of spectacles frame include gender, age, occupation, and clothing. The most important aspect is to consider the fit of the face. When choosing glasses, the frame is best to be on the same level as your eyebrows. Therefore, the eyebrows of customers who choose browline frames should not be too thick, otherwise, they will form abrupt double eyebrows.

You can choose browline frames according to your degrees. The improved version of browline frames is divided into semi-rimless and full-rim, which is suitable for the needs of people of various degrees. People with higher degrees can choose ultra-thin lenses for a more beautiful appearance!

Nowadays, stainless steel frames that are as thin as paper have also joined the browline frames. It is light and comfortable to wear for a long time, which is very suitable for masculine men who often wear glasses and want to maintain a handsome taste.



Why do you need rimless glasses?

How do fishing goggles work?

When fishing in calm water, the light is straight to us. Because of the wind and waves on the water, there will be countless reflective surfaces, just like we face countless mirrors, leading to not clear float. For a long time, eyes will be very tired. Fishing sunglasses block the uncomfortably bright light and protect the eyes from UV damage. All of these functions are achieved by metal powder filters that 'select' light as it comes in.



Common sense of glasses maintenance

Do not wear glasses when doing strenuous exercise to avoid deformation caused by knocking. Take off your glasses when sleeping or lying on your desk to avoid distorting your glasses. Use special glasses cloth to wipe glasses, and can use water and dishwashing essence to clean. Avoid using paper towels, handkerchiefs, or clothes. Deformations of memory materials are not often demonstrated to prevent breakage of joints or welds. If it is uncomfortable to see things, or the frame appears obvious uneven, you need to take it to the optical shop to find a professional to adjust.
