With scientific and technological progress, can meet the demand of modern people’s more focal length lenses followed, 3 focal lens more point 3 area, is a kind of “customize” products, benefit is can relax the ciliary muscle of the eye, and see that each distance more clearly, eyes also not easy fatigue, can reduce the pressure of the eyes, but there are multiple focal length lenses “adaptation”, to adapt to the length of time varies from person to person, when the adaptation period, often cause the average person to coke glasses more misunderstanding, thought that is not worth much coke glasses. Progressive lenses are a high-tech product that needs to be learned. It is recommended to consult an experienced optometrist for glasses.

Let’s take a look at the advantages of multi-focus glasses, because the modern 3C group generally see objects at close range, in order to reduce the pressure on the eyes, its upper area (remote use area) domain adjustment from 6 meters range to 3 meters scenery can be; As for the distance of the lower area (near area), it is adjusted to see the mobile phone and computer screen within 20 cm in order to meet the needs of 3C clan. After adjustment, it shortens the difference of visual rate between the upper and lower areas, which can reduce the pressure of eyes and make the objects more clear and comfortable. That’s why many doctors and optometrists now recommend multifocal glasses.
However, multi-focus glasses are not without their drawbacks. Switching from single-focus glasses to multi-focus glasses requires a period of adjustment, which varies from person to person. Some people need only one month to get used to them, while others need three months. Younger people can adapt to multi-focus lenses more quickly because of the smaller degree difference, while older people have more difficulty adapting to multi-focus lenses when the degree difference becomes larger. Patients with farsightedness also need more time to adapt than those with myopia. This is mainly because people with farsightedness usually do not need glasses to see far and need glasses to assist them to see near objects. Wearing glasses takes less time than those with myopia, so it takes a longer time to adapt.
It is suggested that people should turn their heads when looking at the objects on both sides when wearing the glasses, instead of looking sideways with their eyes. In addition, during the period of getting used to the multi-focus glasses, they should try not to climb stairs or drive a car. During the period of getting used to the multi-focus glasses, they should mainly take indoor life actions to get used to the focal length, and then engage in dynamic activities after getting used to them. People can also take astaxanthin because it works on the muscles, strengthens the ciliary muscles, restores fatigue and improves conditioning, relaxes the muscles, and helps with multi-focus glasses.
In particular, the public should be reminded to consult an optometrist or ophthalmologist if they experience dizziness or difficulty seeing clearly with multi-focus glasses and are unable to adjust. Unless the wearer has unusually strong glasses or irregular astigmatism, it is very likely that changes in the eye itself are causing discomfort, including cataracts, high iOP or eye muscle paralysis. Accordingly appear these circumstances had better seek ophthalmic examination as soon as possible, early detection, early treatment.
