ELEMENTS TO CONSIDER WHEN CHOOSING
When choosing your contact lenses, it is essential to take into account certain elements.
- The material
First of all, you must consider the material. You will have to choose between a rigid contact lens and a soft model.
The former is suitable for people who often have dry eyes. Rigid contact lenses can breathe, thanks to the air and tear drops of their wearer, since they are permeable. They can be used for 12 to 18 months and have the advantage of being practical and do not require special care. You may feel some discomfort with this type of lens at first, but it will disappear after a few days.
Soft lenses are made of soft hydrophilic plastic with a high water content. Even if they require special care, they have the advantage of offering optimal comfort to your eyes.
- Frequency of use
Your choice should be dictated by the frequency of use. You can opt for a contact lens that is frequently replaced. They can be worn during the day and removed at night. They should be changed either weekly or monthly. There are also daily disposable contact lenses which are to be discarded at night. They are often used during sports activities.
- The correction
You should choose a custom-made contact lens according to the vision correction you need. If you suffer from myopia or hyperopia, opt for spherical models. They will adjust to the sinuosity of your cornea. For people with astigmatism or keratoconus, aspheric lenses are best. Thanks to their flattened edge, they offer a clearer vision.
- The color
The choice of the color of a lens depends on individual taste.
These criteria are important when choosing your contact lenses from professionals such as dencott.com. However, the most important thing to consider is the recommendations of your ophthalmologist.
ARE CONTACT LENSES MORE EFFECTIVE THAN GLASSES?
Although they are both ocular devices, there is a significant difference between glasses and contact lenses. On the other hand, an ocular prosthesis is a more voluminous type of contact lens. It is mainly intended to replace an eye that has been totally or partially removed.
Unlike corrective glasses, a rigid or soft contact lens guarantees complete visual acuity. It enlarges your visual field, since it follows the movements of your eye. For optimal vision correction, the alignment of your lenses must be adjusted with the axis of your eyes. This is to prevent a possible alteration of your field of vision.
In addition, contact lenses are more practical, especially when practicing outdoor activities. Whether you sweat or it rains, your vision is always optimal with lenses. Also, they don’t fall out or break like glasses and don’t cause the discomfort of frames.
CONDITIONS FOR OBTAINING CONTACT LENSES
Since 2013, it is now possible to obtain contact lenses without a medical prescription. This is not the case with an ocular prosthesis. However, it is more prudent to consult an ophthalmologist before taking the plunge. He or she will conduct an examination to determine whether you have glaucoma, keratoconus or other vision problems.
In the prescription, your ophthalmologist will mention the following
– Name and brand of lens prescribed;
– The diameter of the lens and its radius;
– The correction required;
– The type of lens care product;
– The duration of lens wear.
In general, the prescription for contact lenses is not identical to that of glasses. It varies according to the nature of the vision problems you suffer from.
BUYING CONTACT LENSES
To purchase your custom-made contact lenses, you can go to an optician. Although the cost is higher with these professionals, you will be assured of quality contact lenses. In addition, you will receive information on how to use them.
Note that a lower than average price is never a guarantee of quality. It is wiser to turn to websites belonging to experts in this field, to be sure to have the right quality-price ratio. Finally, check that the products on sale have the CE mark. This means that the lenses comply with the safety standards imposed by European legislation.
