• Should I wear glasses all the time if I have astigmatism?

  I've got astigmatism and farsightedness and have been wearing glasses all the time as what my doctor suggested me. Everytime when I remove my glasses I cannot see clearly even the near things. Maybe not to wear them if you have astigmatism will get you a worse vision.

• What are the reason for myopia?

  Myopia is also called nearsightedness, it is a refractive disorder where distant object cannot be seen clearly. This condition occurs because light rays coming to an eye from distant object focus in front of retina and the resulting image on the retina is blurry. The most common reason for myopia is elongation of an eyeball and normal refractive power becomes too strong for an eye. The images formed on the retina are blurry and therefore cannot be seen clearly. This form of myopia is known as axial myopia. In some rare cases it is possible that refractive power of an eye is too strong for a normal size of an eyeball and images from distant objects again focus in front of retina instead on it. The reason is either a strong refractive power of cornea (for example in condition known as keratoconus), or lens (for example condition known as lenticonus.

• Can I wear my glasses while reading books and playing computer?

  It is not necessary for you to wear glasses special for nearsightedness to read books or playing computers, if you can clearly see near objects. You can use your glasses only when you see things in far distance. But, please remember whenever you have problem see near distance, you may need another pair special for reading or computer use.

• Should I wear my glasses all the time if I can see things at close?

  If your prescription for nearsighted is strong (especially more than -2.0--3.0), you are suggested to wear glasses all the time, even if you can see things clearly at close.

• Do all sunglasses have the protection of uv rays?

  Prevention of UV radiation is almost the first concern for people to choose sunglasses. Except for sunglasses which are labeled as "cosmetic', all sunglasses offer the protection of UV rays.

• how is your vision like when you take the glasses off if you are nearsighted?

  That is depend on the power of your eyes. If higher your prescription is, the more blurry your vision will be. I know someone who is almost blind when he takes off his eyeglasses.

• Can I reduce myopia by doing eye exercises?

  Probably not, some American officials stated out that there is no evidence that do-it-yourself eye exercises has any effect on reducing myopia. But eye exercises can reduce the eye strain which will make you less tired in your eyes.You'd better keep wearing your eyeglasses which you use for myopia, and take off the glasses to have a rest after long time near vison works.

• Is it possible for me to get contacts if I have different eyesight?

  Yes, it is possible for you. You can ask your doctor for seperate prescription on each eyes. To be specifically, one contact lens for nearsightedness, one for non-prescription lens.
