Contact lenses and frames, for example, can correct the difference in radiance (like).
Today, compare these two common mirrors.
Children can use contact lenses, mainly RGP. Let’s start with the advantages of RGP:
No eyeglass burden, without prejudice to appearance and motion.
2. There is a wide range of dilatory differentials that can be modified for a high-level near-sighted type.
This is better than a frame such as glasses, and one-sided thickness of lenses such as luminous luminous spectrometry at a single-eye height is exaggerating and seriously affects the weight of the two sides (which is difficult to fully address even with a re-engineering programme using a simulating mirror).
Frames such as glasses can successfully solve the problems of one-eye vision of a wide range of luminous differences, which, after re-engineering, can be very small.
3 Questions of disharmony (regarding RGP designed by Toric) and irregularity of fracturing.
Map above: RGP lenses
And again, RGP’s shortcomings:
One, expensive.
The price of the lens is more than twice the price of a frame mirror, based on official price.
As with frame mirrors, children ‘ s dilatoryness varies from year to year, and RGP lenses need to be regularly evaluated and adjusted.
2. Daily care is cumbersome.
Day-to-day stripping, cleaning, storage, proteins, regular inspections/rereviews, polishing. Parents need more time to do this.
The risk of accidentally crushing/breaking or falling out of contact lenses during the process of cleaning cannot be minimized.
By contrast, the frame mirrors are a little bit less – just wake up in the morning and wear them.
3. Risk of injury to amphibious membranes.
There is little chance of serious amphibious amplitude damage in the mirror process and in the professional process before and after sale.
These risks are increased by poor routine hygiene practices, inappropriate removal methods and inadequate mirror maintenance.
Contact lenses do not vary between the effect of correction and the effect of modification between the image of the axial glaucoma.
Whether or not the axle or the glaucoma, can be measured by eye biology. It does not vary in effect, but it can also be made clear through a test that does not match a quantitative multiplier (e.g., a semi-director test for 3D light).
Focusing – The advantages of RGP are almost the disadvantages of frames like glasses; the disadvantages of RGP are almost the advantages of frames like glasses.
Three points should be noted:
A. Frameworks such as lenses can be dealt with, both axle and glaucoma. Except in the case of single eyes.
B. Even with the use of contact lenses to improve the image, it is necessary to stop wearing contact lenses and to wear frame glasses during periods of child allergies, amniotics, abdominal lesions resulting from upper skin injuries or cold fever. In order to maintain a smooth transition of contact lenses and frame lenses, the frame mirrors must be the preferred equivalent.
The variation of parameters, such as C, framework, like glasses, is modifiable (this is more ad hoc) and RGP is irreconcilable.
That is not enough.
