The best you can do is take very good care of your eyes. This may not prevent the astigmatism from becoming worse though. You can slow the rate at which it worsens by not putting extra strain on your eyes. Make certain that your prescription is up to date, that you always wear your glasses (wearing glasses everyday has been shown in some cases to improve vision, while wearing contacts has been show to slightly worsen vision) and make certain your glasses are well fitted (by your optician), clean and in good shape. Always wear sunglasses when in bright light and if you spend a lot of time in front of television or computer screens make sure the image is large enough and that you do not sit too close to tube-style screens. If possible switch to LCD. Glasses with glare-reducing coatings can help also, these can be more prone to scrating though. It may be best to get glare-reduced reading glasses and scratch-free coated glasses for out-and-about wear. Any astigmatism may worsen over time but your optometrist can help you manage it.

The corrective lenses needed when astigmatism is present are called Toric lenses and have an additional power element called a cylinder. They have greater light-bending power in one axis than in others. They are also known as Cylindrical Lens.

spherical aberration can corrected by using spherical lenses such as the planoconvex lens and chromatic aberration can also be corrected by using the achromatic doublet ie the flint and glass crown.

The only way to treat astigmatism is to get corrective lenses. You can choose between contact lenses or eyeglasses and this will correct your vision.

Depending on the degree of astigmatism, it is often possible to correct it with contacts. These type of contacts are called "toric" contacts and reshape the cornea to correct astigmatism.

There are two types of astigmatisms, corneal astigmatism and lenticular astigmatism. Both of these types can be addressed and corrected by laser eye surgery.

Is microscopic lens corrected for chromatic aberrations?

Not all microscopic lenses are corrected for chromatic aberrations. Many times they will be for use in some places like laboratories and similar.


Is your lens corrected for aberrations?

not totally, chromatic aberrations can be minimized by the use of filers (usually blue); or by lenses corrrected red, blue, and other wavelengths, called apochromatic lenses. The most loogical, but most expensive method of eliminating chromatic aberrations is to use a light source of one wavelength, or monochromatic light.

Can spherical abberation be corrected by combination of lenses?

Spherical aberration can be minimized by several methods: Changing curvature of both surfaces of a lens allows sharp focus at a particular distance. Aspheric lenses - i.e. lenses with a special non-spherical profile, is another.

What limits the size of a refracting a telescope and why?

Mass. A refracting telescope needs to be either really long, or have really thick lenses. In either case, the mass of the telescope limits how large you can make it, if you want to be able to change its direction.
