I believe it is the argon laser.
Concave and Convex
It depends on what the vision 'problem' is. Convex lenses are used to correct short-sighted errors, while concave lenses correct long-sighted problems.
One can get laser eye surgery procedures in Akron from Clear Choice. This is a center that deals with eye surgery to give clearer vision. With laser eye surgery, one does not need to have contact lenses or eye glasses. This type of eye surgery is used to correct problems that has to do with far-sightedness or near-sightedness.
The skin conditions that a laser can correct are fine lines or wrinkles around the eyes, mouth or forehead. Shallow scars from acne or if one has non responsive skin after having a facelift. These are the types of problems that are the easiest to get fixed.
Laser vision correction surgery can and often does require revision at a later date. Night vision is often severely affected with this type of surgery, and a second go round is often needed to help with this problem.
A YAG laser surgery is a surgery for cataracts. Cataracts are what makes a persons vision blurry or cloudy. The laser surgery makes it so that person can see better after they have the surgery.
They are with the Third spy to get to the third spy type in the box: where do you get the ultra vision goggles on poptropica? and you will get the answer good luck!
It depends on how young you are and what type of eye problems you have. There are many diseases of the eye so have it checked out and talk to a good Opthamologist. she is having hyper myopia ans she wear a specs of - 13 in the age of 4

LASIK can correct a wide range of vision problems related to the need for glasses or contact lenses. Ametropia, the condition of having an eye which is out of focus can be caused by a mismatch between the cornea and the optics of the rest of the eye resulting in light not being focused properly on the back of the eye to produce a clear image.The most frequently corrected vision problem is myopia or nearsightedness. Also correctable is farsightedness or hyperopia. Also there is a condition of assymetry of the cornea which is called astigmatism, and this can also be corrected by LASIK.Of interest is that many patients have a combination of two of these conditions together and this can also be corrected by LASIK. Most commonly nearsightedness with astigmatism. Also there is farsightedness with astigmatism. More uncommon is what is called "mixed astigmatism" where the eye is both near and farsighted at the same time in different meridians or directions. All of these conditions can be effectively treated with LASIK.More recently there is even the correction of irregular shapes in the cornea which are correctable by a variety of new methods of custom treatments. There is wavefront treatments based on the overall shape of the eye and topography guided treatments based on the shape of the cornea in a particular patient. Most patients do not need or derive additional benefit from these types of treatments, although wavefront "optimized" custom treatments have been found to provide better quality of vision and are widely used by advanced lasers available today.Other eye problems and diseases are not treatable with LASIK. Included is amblyopia or a lazy eye and presbyopia or the aging eye. In addition blurry vision due to diseases such as cataracts or glaucoma are treatable but not by LASIK procedures.For most people, if their vision is correctable with glasses or contact lenses, it will also be correctable in a more permanent way by LASIK vision correction.
Low level laser also referred to as a cold laser.
