There are many varieties of eye glasses in the market today. If you go to a major store like a mall, or Wal-Mart, you can easily get a prescription eye glasses or contact lens that come in many different styles. However, there is another kind of glasses that is not widely known which can be used to improve far sighted or near sighted problems. This kind of glasses is known as .
So what are ? are glasses with small openings that are supposed to improve the vision of the persons wearing them. They are sometimes called stenopeic glasses: stenopeic is a Greek word that means "little opening". These tiny openings or pinholes allow lesser amount of light to enter the eyes. This is similar to when you make a fist and look through the tiny opening in your fist. You can see objects clearer inside the opening that your fist makes. So this is how work. Lights from outlying areas are blocked out while allowing into the eyes the lights that go into the middle part of the pupil. Refractive error is reduced and a person's vision is improved.
improve vision at all distances. They cost less than prescription glasses but a little bit more than reading glasses. The wearer will notice very little glare or distortion. will work the entire lifetime and need very little maintenance.
come in two different styles: traditional pinholes and modern pinholes. Traditional pinholes have wider lenses with a little curvature. You can see the holes in the lens. The traditional styles do lessen the amount of ultraviolet light. On the other hand, the modern pinholes are more attractive in design with look similar to sunglasses. They provide full protection from ultraviolet light. The holes are not easily noticeable by other people.
Eye Make Up Glasses
LASIK is a surgical procedure that can reduce a person's dependency on glasses or contact lenses. The procedure permanently changes the shape of the cornea (the delicate clear covering on the front of the eye). For clear vision, the eye's cornea and lens must bend (refract) light rays properly, so that images are focused on the retina. If the light rays aren't clearly focused on the retina, the images you see are blurry.
LASIK stands for Laser-Assisted In Situ Keratomileusis and is a procedure that permanently changes the shape of the cornea, the clear covering of the front of the eye, using an excimer laser.
What is the real difference between conventional Laser Eye Surgery and Custom LASIK Eye Surgery?
Conventional Laser Eye Surgery
Conventional Laser Eye Surgery treats the vast majority of common optical aberrations called "lower order" aberrations. These are responsible for causing nearsightedness, farsightedness and astigmatism. Custom LASIK Eye Surgery provides a more precise treatment for patients who have "higher order" aberrations, which we can now measure with the Aberrometer. For these patients, customized laser eye surgery may provide a better quality of vision by measuring and addressing all of these aberrations as part of the treatment plan.
During LASIK surgery, a small incision is made in the cornea to create a flap. Then, a laser beam works within the cornea to reshape it for vision correction. After the reshaping, the flap is put back into place and serves as a sort of natural bandage.
Will I Need Reading Glasses After the Treatment?
Generally, patients under 40 years of age read well without glasses following the treatment. Patients over 40 may need magnification for reading fine print.
Presbyopia is the term that refers to the natural weakening of the focusing muscles that occurs in our early to mid 40s, causing us to need the magnification that reading glasses provide. The LASIK treatment does not correct or prevent presbyopia. We also will be glad to discuss another option called monovision.
