Definitions
- the present invention relates to a presbyopia contact lens, and more particularly, to provide both a far field and a near field of view in one contact lens while varying the size of the far field and near field of view of both eyes according to the predominant and the thirteen eyes.
- Long-distance field and near-field area magnification of dominant eye and low-eye eye are continuously formed so that the middle distance area is partially overlapped, so that the short-range field of vision can be continuously provided at a long distance by the neural summary phenomena that selects the best visible image of both eyes.
- the present invention relates to a presbyopia contact lens.
- the human eye is roughly similar to the structure of a camera.
- the cornea located at the very front of the eye and the inside of the sclera are irises that function as apertures to control the amount of light.
- the lens acts as a lens to form an image
- the retina acts as a film to form light through the cornea and lens
- the ciliary body acts as a distance adjuster so that the image of an object is accurately formed on the retina by changing the thickness of the lens. have.
- the lens having a similar function in the human eye is fixed in place by the ciliary body. In this state, the thickness is changed so that the image is clearly formed on the retina.
- the lens consists of an elastic and convex lens shape having a thickness of about 4 mm to adjust the degree of refraction of light coming through the pupil.
- the lens is contracted and the lens is thickened.
- the muscles of the ciliary body relax, the thickness of the lens becomes thinner, and the light refraction decreases. The object can be seen clearly.
- the visual function provided by the human eye is a complex function, and it can be divided into four elements, which are divided into minimum visible, minimum resolvable, minimal legible, and minimal discrimination. .
- the visibility may be referred to as the sensitivity of the retina, and the amount of light and the background play an important role rather than the size of the object. In other words, contrast plays a big role.
- the separation force refers to the ability to recognize two points or lines separated by two is called resolution and general vision. This may be called the minimum angle of resolution and minimum separatibility.
- the threshold is 30 seconds to 1 minute in normal people.
- the size of the macular vertebrae is 1.0-4.0 ⁇ m. If we want to recognize that the two objects are separated, the distance between the two phases in the retina should be at least 1.5 ⁇ m, which is about 20 seconds.
- the minimum time of clinically measured normal person is 30 seconds ⁇ 1 minute. A typical method of measuring this is the Lantolt's rings. It was first recognized as the International Sight Table by the European International Conference in 1909.
- the eye's vision can be determined at a distance of 5 mm, but it cannot identify a smaller mark. Is 1.0. At a distance of 5m, the distance of 1.5mm is the visual angle of 1 minute. Visual acuity is represented by the inverse of the minimum time. The visual acuity of an eye with a minimum time of 2 minutes at a distance of 5m is 0.5, and if it has a minimum time of 0.1 and 30 seconds for 10 minutes, it becomes 2.0.
- the readability refers to the ability to recognize letters, numbers, or shapes. In addition to the physiological function of the eye, psychological factors (intelligence, attention, experience, etc.) are involved.
- the discernment may recognize what it is when a person sees an object or an alien but where is it, how does it move, and is the array normally placed? Is it upright? See if it is tilted. Examples include array vision, tilt vision, movement vision, and stereoscopic vision. It is thought that recognition is performed by different mechanisms such as separation ability, readability, etc. because the recognition itself is performed at a distance (about 20-30 seconds) within one cell.
- the depth of focus increases, even if the refractive error is not completely corrected, the visual acuity increases. This is why myopia is frowning.
- the pupil is too small (0.1-1 mm or less), light diffraction occurs and the retina's illumination decreases, reducing vision.
- the pupil diameter of 2.5mm ⁇ 6mm There is no difference between the pupil diameter of 2.5mm ⁇ 6mm, but if it is larger than that, spherical aberration occurs and vision decreases.
- the lens when the lens works properly due to healthy eyes, the lens is automatically adjusted to focus well when looking at objects near or far away.However, as the age gets older, the lens loses its elasticity due to aging of the lens. It is degraded, and thus, when looking at an object at a close distance, it is out of focus and blurry and hard to see.
- presbyopia is corrected through eyeglasses, contact lenses, or surgery.
- a multifocal lens progressive lens in which one lens has various degrees of power is used to target objects at near, intermediate, and long distances. While correction is relatively easy to see for everyone, contact lenses are somewhat difficult to correct.
- the multifocal contact lens which is a presbyopia contact lens
- side effects such as reduced contrast sensitivity, night vision impairment, and neuroadaptation may work compared to the single focus.
- the refractive index of the presbyopia contact lens is 0 D (diopter) for both eyes and 2.0 to 3.0 D for the near eye, so there is an invisible medium-distance field of view. There is a problem that causes diplopia and confusion.
- a presbyopia-focused hard contact lens of Korean Unexamined Patent Publication No. 10-2011-0118236 (published on Oct. 31, 2011; hereafter referred to as 'Previous Document 1') was proposed.
- the prior art document 1 relates to a presbyopia-focal hard contact lens having a lens center circle for viewing a long distance formed in a central portion, and a lens peripheral root part for forming a lens near the lens center for a near distance formed.
- Prior art 1 has a disadvantage in that since both eyes have the same range of distance and near frequency, the intermediate region that is hardly visible between the far and near is difficult to recognize continuous images from far to near.
- a presbyopia contact lens of Korean Patent Registration No. 10-1578327 (registered Dec. 10, 2015; hereafter referred to as 'Previous Document 2') was presented.
- the prior art document 2 consists of a lens body which is composed of a far-field portion having a far-field refractive power and a near-field having a near-field refractive power and is in contact with the cornea, and allows the lens body to simultaneously focus far and near focus at the time of departure from the center of the cornea.
- the frequency range of the far section of the lens body is -10.0 ⁇ 4.0D
- the frequency range of the near section is 1.0 ⁇ 4.0D
- the surface of the lens body is formed with a plurality of pores for the air permeation and nutrient supply as a whole

- the thermal lattice may have a target refractive index of -0.5 diopters (D) at a remote site and a target refractive index of -2.25 diopters (D) at a near site.
- the binocular is divided into predominant and ten eyes, and the contact ranges used for the divided eyes are formed differently, but by increasing the depth of focus, the intermediate area is partially overlapped to improve the visual acuity in the middle area. Because of the zone, the difference in refraction between the far and near areas is lowered, thereby improving the adaptability when using the patient.
- the ratio between the predominant eye and the low eye is different depending on the distance between the long-range and short-range areas of the contact lens. Therefore, the visual acuity can be easily seen by the neural summary phenomenon that selects and recognizes a good image from both eyes. Expanded range has the effect of improving the patient adaptation by wearing.
