Technology Field

[0001] The present invention relates to ophthalmic lenses, and more particularly to multifocal ophthalmic lenses. Background Technology

[0002] With the widespread adoption of 3C products, the incidence of myopia among children and adolescents is showing a trend toward younger ages. Consequently, the proportion of patients with high myopia is significantly increasing, and vision problems are not limited to myopia and hyperopia but are often accompanied by symptoms of astigmatism. When light passes through the cornea and focuses normally on the retina, it can form a clear image. However, if light fails to focus at a single focal point and forms multiple focal points, astigmatism occurs. This causes problems such as image distortion, image damage, and blurring in both distant and near vision, severely affecting the quality of vision.

[0003] The primary traditional method for correcting visual deviation is wearing ophthalmic lenses, such as contact lenses. The refractive power design of conventional multifocal ophthalmic lenses typically adopts a method of gradually increasing power from the central zone to the outer zone. This pattern of power change often causes discomfort to the wearer and is difficult to endure, particularly during prolonged use, which can actually hinder the effectiveness of visual control. The problem to be solved

[0004] In light of this, the objective of the present invention is to provide an ophthalmic lens that offers a multifocal diopter design and allows the arrangement of refractive powers to be arbitrarily changed according to vision correction requirements, thereby providing an effect that reduces visual fatigue and offers a clearer and more comfortable effect when worn. means of solving the problem

The ophthalmic lens has a first refractive correction area, a second refractive correction area, a third refractive correction area, and a fourth refractive correction area defined therein, and the first refractive correction area, the second refractive correction area, the third refractive correction area, and the fourth refractive correction area are arbitrarily positioned in a central optical zone, a first outer ring optical zone, a second outer ring optical zone, and a third outer ring optical zone, and the ophthalmic lens has a refractive power distribution curve, the first refractive correction area represents a horizontal straight line in the refractive power distribution curve, and the second refractive correction area, the third refractive correction area, and the fourth refractive correction area each represent a waveform in the refractive power distribution curve, and the second refractive correction area, the third refractive correction area, and the fourth refractive correction area each have at least one peak; the ophthalmic lens has the following range: 3.5mmZ1+Z2+Z3+Z4 5.0 mm is satisfied, and Z1 is the interval in which the central optical zone extends from the center point to the boundary of the central optical zone; Z2 is the interval in which the first outer ring optical zone extends from the boundary of the central optical zone to the boundary of the first outer ring optical zone; Z3 is the interval in which the second outer ring optical zone extends from the boundary of the first outer ring optical zone to the boundary of the second outer ring optical zone; and Z4 is the interval in which the third outer ring optical zone extends from the boundary of the second outer ring optical zone to the boundary of the third outer ring optical zone. Effects of the invention

[0006] The effect of the present invention is that the ophthalmic lens, through the design of multifocal refractive power, provides an effect that reduces visual fatigue of the wearer, thereby providing a clearer and more comfortable effect when wearing the ophthalmic lens, and the ophthalmic lens can arbitrarily distribute the first refractive correction area, the second refractive correction area, the third refractive correction area, and the fourth refractive correction area to the central optical zone, the first outer ring optical zone, the second outer ring optical zone, and the third outer ring optical zone according to the vision correction requirements, and by adjusting and arranging the refractive power for each refractive correction area, the diversity of the refractive power arrangement of the ophthalmic lens is increased.
