Ray Ban Outlet sunglasses with the required data: spherical power / SPH, astigmatism / CYL, astigmatism axial / AXIS, IPD / PD (there must have axial astigmatism, not only the degree of astigmatism and IPD can)

Standard eye degree format (example) - Note: You must be written sequentially left right

R (right): -500/125 * 180 (spherical power SPH / CYL * astigmatism axial AXIS)

L (left): -450/175 * 175 (spherical power SPH / CYL * astigmatism axial AXIS)

(Note: If you have astigmatism, there must be axial)

PD: 62 (IPD)

◎ Please nearest to the optometrist specialty hospitals, eye clinics, optician optometrist measured by the degree, and remember to obtain prescriptions.

For astigmatism contact lenses fitting
Article publié le 23/06/2013
A ball of light recessive Ray Ban Outlet Sunglasses for astigmatism correction

1, the spherical lens in the above-3.00DS corneal astigmatism-1.00DC or less, the light with a ball lens correction; because the ball surfaces within the optical lens have the same radius of the meridian, and the two main meridian corneal astigmatism different curvature, there must be a space to be filled with tears, forming - tear lens, make up the differences of the meridian of the cornea. Central thickness and elastic contact lenses correct astigmatism effect is good, and sometimes even can correct astigmatism 2.00DC.

2, for corneal astigmatism> 1.00DC and astigmatism <1/4 degree spherical, astigmatism can be 1/2 plus mirrors the ball, and then converted into contact lenses give wearers.

Namely: total DS = DS (formerly optometry ball luminosity) +1 / 2DC (formerly optometry astigmatism luminosity)

Example: The original optometry as:-8.00DS-2.00DC × 180 °
Then: Total DS = (-8.00) + (-1.00) = -9.00, translated into the contact lens prescription-8.00DS.

3, for corneal astigmatism> 1/4 spherical degree, for example: optometry as:-4.00DS-2.00DC × 180 is applied special soft contact lenses to correct astigmatism.

(Note: The ball of light invisible Cheap Ray Ban Sunglasses can correct astigmatism, crystal soft contact lenses astigmatism required)

Second, astigmatism contact lens fitting

A, astigmatism soft contact lens design features: axial remained relatively stable - up and down movement may have a certain degree, but can not have a significant axial rotation, the comparison of different design methods design types thicker heavier type cutting edge up-down thinning type (gravity Stabilization Act) (truncate France) (Dynamic Stability Act) under the prism lens design principle of design, that is below the cut to the next part of the lens, the lens of the corresponding portion of the upper and lower side thicker heavier, with the lack of gravity prevents side portion fixed to the lower eyelid gradually thinning, the upper edge of the lower eyelid muscles rotate the lens to achieve the purpose of preventing rotational force of the advantages of the lens fixed axial astigmatism can be maintained at a relatively comfortable to wear lenses, no foreign body sensation; lens fixed position relative stability can move around with the eye, but can not rotate; average thickness reduction, high oxygen permeability is worldwide patented design flaws eye movements, the lens does not turn the eyelid with a significant foreign body moved; lower than the heavy, lower eyelid obvious foreign body sensation (TV Astigmatism lenses using the up and down thinning type)

2 Indications: rule astigmatism, Cheap Ray Bans degree rotating lens stabilization, lens rotation angle <± 20 degrees. "

Small-diameter telescope, should select low rate 20-40 times, 50-80 times magnification options, selection of high-rate 100-150 times.

2, Finder has a larger-diameter should be chosen for good

Small telescope magnification 5-12 times are generally finding satellite device, the actual field of view angle is 6-14 degrees. Star is good or bad for performance, greatly influences the telescope observation capacity. Diameter should be as large as some of the Finder, with 30-50mm as well. In addition, to the Finder, and cross have played a very important role. Buy telescope, you should carefully check whether finder scope cross-hairs attached devices.

3 to select, solid and sturdy tripod

Telescope optical performance is high, without a good supporting instrument tripod, its value will be greatly diminished. Just think, a little bit of wind on shaky legs how can play a good instrument performance. Because the telescope's field of vision is very small, especially when a high rate, with a little bit of vibration, would run out of sight of the image, so it is difficult to see the observation object.

4, the Equator ceremonies, and latitude and longitude

Telescope bearing bracket-longitude and the Equator ceremony stand in two types. Tube can be turned horizontally and vertically-bracket called latitude and longitude. Tube around the polar axis (right ascension axis) rotation, while orbiting perpendicular to the polar axis (declination axis) rotation of the stand is called the Equator ceremonies, and their different talents.

Jingle bracket than the Equatorial ceremony strut has a simple structure, light, mobile and smart, tube to bottom and turning around freely, even if the person is not familiar with also makes it easy to use this water. A little trouble is, in order to track out of the view of the stars. Must continually make equipment from top to bottom and move around. To the observer, probably won't feel so free.

Advantages of the Equator ceremonies are. It can track the stars into view, because Cheap Ray Bans tube to rotate around the polar axis. And you can also install the stars in the night sky are like shooting the camera.

To the polar axis is on the Polaris. Even unskilled people, the operation will not be too difficult.
