Wearing colored contact lenses is common, especially for aesthetic reasons. These accessories allow you to change the look of your eyes and your gaze. But their use is not limited to fashion, because corrective lenses are produced by specialists. This is an excellent alternative to glasses that has many advantages.
These comfortable, practical and quiet ocular prosthetics help improve the vision of people with presbyopia, astigmatism, myopia, hyperopia, and, among other diseases, keratoconus. In these cases, it is necessary to consult an ophthalmologist and provide a prescription when purchasing it.
Types of lenses suitable for each correction procedure
Contact lenses can be classified into three main categories, including:
- Solid lenses
- Soft lenses
- Colored lenses.
The ophthalmologist prescribing the wearing of these accessories usually indicates the appropriate type of correction. On the other hand, colored lenses are not considered medical devices, but rather accessories.
Soft lenses, ideal for farsightedness and nearsightedness
For these two most common types of immobility, specialists recommend wearing soft and aspheric lenses. This model is comfortable and easy to apply, as its shape perfectly matches the curvature of the eye surface. As with glasses, these ocular prostheses must have a positive power for hyperopia and a negative power for myopia. Farsightedness is a near vision problem, where a person cannot read or see close objects clearly. Myopia does not allow those affected to distinguish objects at a distance.
Toric lenses are ideal for astigmatism
Astigmatism is one of the frequent vision problems, due to irregular curvature of the cornea. People with this deficiency may not be able to see clearly. Blurred vision often accompanies farsightedness or nearsightedness. For this squint, the Toric lenses Recommended, whether flexible or rigid. This type of lens is somewhat geometric in shape, having the appearance of a donut cut in two. It is characterized by the peculiarity of having different refractive powers at the horizontal and vertical levels according to the needs of each eye. Its severity depends above all on the axes required for correction.
Rigid lenses, ideal for various cases of ametropia and keratoconus
Rigid lenses or gas permeable lenses can be used to correct various vision asymmetries when soft models are not suitable. However, they are mainly recommended to improve vision in people prone to keratoconus. This is a corneal deformity that tends to take on the appearance of a cone.
Progressive lenses for near and far scenes
As we age, near vision begins to deteriorate and wearing well-suited glasses or contact lenses becomes essential for most people. In the event that a person is also nearsighted, but also suffers from presbyopia, these prosthetics make it possible to correct both deficiencies. In fact, progressive (or multifocal) lenses have many refractive points.
Colored contact lenses

Whether corrective lenses or not, different tints are generally available from manufacturers. the Colored contact lenses Changing the color of the iris and making a slight difference in its appearance, making it clearer, deeper, luminous, etc. The choice of color is completely up to each person and depends on the desired results.
