RGP glasses and common invisible glasses which good?
RGP glasses and ordinary contact lenses which good?
First of all, contact lenses are lenses worn on the cornea of the eye to correct vision or protect the eye, also known as corneal contact lens.Contact lenses from the aspect of appearance and convenience to myopia, hyperopia, astigmatism and other refractive patients have brought a great improvement, and a wide field of vision, realistic vision, in addition to control the development of myopia, astigmatism in young people, the treatment of special eye diseases also played a special effect.
Contact lenses are divided into soft contact lenses and hard oxygen permeable contact lenses according to the material of the lenses. Soft contact lenses are more comfortable to wear and have become a more popular type of lenses so far.Hard contact lenses are generally made of PMMA polymer. In recent years, hard oxygen permeable contact lenses (RGP) have become more popular.
RGP glasses are hard oxygen permeable corneal contact lenses. RGP contains polymers such as silicon and fluorine, which can greatly increase the amount of oxygen passing through.Compared with the soft contact lens, it not only improves the oxygen permeability, but also determines the firmness of the material, and has good wettability and anti-precipitation.
What are the advantages of RGP glasses?
1. Good physiological compatibility.
2, high oxygen permeability.
3. Due to the problem of material hardness, it can have a certain shaping effect on the cornea, and it can delay the progress of some flexural myopia. Of course, this effect is also effective for keratoconus.
4. Also due to the hardness of the material, it is not easy to deform and can correct the relatively high astigmatism.
5. The maintenance is relatively simple and the service life is long. Under correct care, the lens can be used for two years, and the long-term use of the lens is relatively cheap.
RGP contact lens life
Although the RGP is more expensive, it has a very significant advantage: durability.Unlike soft contact lenses, which are prone to dry, crack and deformation, RGP contact lenses have excellent strength and toughness, and are less prone to scratches, cracks and sediment accumulation.Easy to clean, simple maintenance, long service life, if properly maintained, a pair of lenses can be used for at least 2-3 years.
However, RGP (breathable rigid contact lens) can only be tested specifically by a professional eye hospital to see if your eye is fit.The main contents of the examination include corneal curvature, intraocular pressure, corneal endothelium, contact lens trial, etc. In addition, it is best to accept the trial first to see how their tolerance is, because RGP contact lenses have higher professional requirements, so the cost is higher.In addition, RGP requires a high level of professional technology and hardware equipment. Therefore, it is recommended that patients should go to a professional eye hospital for testing and matching.
