• 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.

• 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.

• 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.

• Are there any alternative treatments for myopia except for eye surgery?

  You can probably choose other methods to cure your myopia, vision training or eye exercises, discontinuing close work, reducing eye strain by taking a rest break during periods of prolonged near vision works; and wearing bifocals to decrease the need to accommodate when doing close-up work.Lasik surgery is one of the way to treat myopia which can make you less independent on eyeglasses and contact lenses.

• 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.

• 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.

• 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.

• Why can I see tiny small coloured dots move around?

  Yeah, it is common to some extent. Colored dots maybe caused by the special coatings on your glasses, especially when you look through sunlight. Small distortions is also common when looking through lenses, especially if you have strong prescription.If you still feel uncomfortable, you can go back to your eye doctor to check if there is something wrong with your prescription.
