Eyes are our windows to the world. Yet they are subject to ruthless torture by glaring screens, unhealthy lifestyles, and sometimes genetic predispositions that ensure that you have no means of escaping multiple visits to the eye doctor. Partial visual impairment can be caused by macular degeneration, diabetic retinopathy, cataracts, floaters, night blindness, migraine, glaucoma, and the most common – myopia, astigmatism, and hyperopia.

Of the many treatments to improve vision, the most simple is vision therapy and vision training. The eye is trained with behavioral exercises to make to make way for eyes which will be better equipped to deal with stress on them. However, such exercises are limited in their corrective capacity and will fall short of treating inherent eye problems. Routine medical examinations like dilating of the pupils, Refraction, Tonometry, and the slit-lamp examination can determine the nature of the problems that a patient might be suffering from.

In case of presbyopia or aging eyes, progressive lenses, bifocal glasses and reading glasses are offered as remedies to the gradually ebbing ability of the eyes to focus.

For myopia or nearsightedness, the remedial measures which doctors usually prescribe are convex lenses, contact lenses, corneal implants, photorefractive keratotomy, radial keratotomy, and Lasik Eye Surgery.

For hyperopia or farsightedness, the practical troubles are significantly fewer, and so treatments are not advised until the patient is extremely hyperopic. In such a case the treatment options remain the same as they would in case of myopia.

When it comes to astigmatism, or distortion of the object of vision, the only alternative to corrective glasses is Lasik Eye surgery.

While nearsightedness, blurring, and shortsightedness are corrected by doctors through the use of prescribed corrective glasses or contact lenses, glasses do not take care of the host of problems that impaired vision may arise from and may cause in the future.

Lasik is one resilient and long lasting remedy to impairment of vision. Done with the aid of the laser beam, this surgery reshapes the cornea so that the path of light passing through it is straight and directly hits the retina at the back of the eye. A corneal flap is created prior to the application of the laser. LASIK stands for laser in-situ keratomileusis and has grown to be quite popular among long time users of spectacles and contact lenses. Lasik is quite capale of curing deficiencies in vision and is a relatively painless procedure, as the patient is usually anaesthetized during the process. Another reason for its growing demand and popularity is that the Lasik Eye Surgery does not require post-operation bandages and is bloodless. This is why it dramatically reduces the time required to recover after an operation to a mere 24 to 48 hours. The improvements are apparent almost immediately after the surgery and are long lasting.

Like the LASIK, but not as commonly prescribed is the LASEK (Laser-Assisted Sub-Epithelial Keratectomy or Laser Epithelial Keratomileusis) surgery. While both use ultraviolet beams to make changes to the cornea, in the LASEK, unlike the LASIK, the outer corneal layer is loosened or removed and not positioned as a flap. As a result of the obvious repercussions of such a complicated procedure, recovery from LASEK is a lengthier deal, even though the end results may eventually be similar.

It is important to get routine eye checkups these days, thanks to the increase in pollution levels and the increased vulnerability to diabetes and other lifestyle related diseases. Whichever remedial procedure your doctor prescribes you; make sure to talk to him in detail about it, so you are aware of the complications and benefits of it.
