Discover a comfortable all day wear contact lens that can last as long as one month. The unique ultra-smooth surface technology allows the tear liquid to spread evenly across the contact lens creating a protective layer of moisture on the surface that resists deposits better than usual soft contact lenses.
What is Myopia/Nearsightedness?
Myopia or Nearsightedness is a very common condition of refractive errors / eye imperfection in which objects at a distance appear blurry and objects nearby can be seen clearly.
The reason for this is that the eyeball is too long or the cornea (the clear part of the front of the eye) is curved too strong. In both cases light does not get focused correctly and distant objects seem blurred. Nearsightedness usually develops during adolescence until the age of 20. The reasons for Myopia can be hereditary as well as consequences of stress and also extensive computer work and close distance reading.
Additional Information: Patients with Myopia (Nearsightedness) have a negative prescription power (-).

What is Hyperopia/Farsightedness?
Hyperopia or Farsightedness, is the opposite way of nearsightedness but also one of the common refractive errors / eye imperfections which can be inherited and eventually might need correction. If a person is farsighted, objects that are close-up appear unclear but distant objects are seen clearly. Often, it can lead to headaches or difficulties to concentrate when working at close distance.
Most people are born with some farsightedness, yet the timings and experience varies. There is no way around to prevent farsightedness since it occurs naturally when the eye ball is shorter compared to normal or when the lens of the cornea is irregularly shaped. Hyperopia can be detected with a comprehensive optometric examination after which the prescription power is defined. A small farsightedness can be corrected by the eye itself while a stronger farsightedness will lead to the above described symptoms and has to be corrected with the help of eyeglasses or contact lenses.
Additional Information: Patients with Hyperopia (Farsightedness) have a positive prescription power (+).

Note: Contact lenses with or without prescription power should always be fitted by an optician or eye doctor
