Visual impairments are very common in modern days with lots of work load on our eyes. Contact lenses are very practical, simple and safe for our eyes compared to other options such as wearing glasses or having to undergo LASIK surgery. Contact lenses have a big advantage over glasses by providing total coverage over the eye, provide the same correction of both direct and lateral vision. Choosing a contact lens that is comfortable must be done so with your ophthalmologist.
Choosing the best contact lens
Choosing contact lenses is a serious matter and must be done by your ophthalmologists. Depending on your case, your eyes might require different type of contact lenses. For example, you might be getting contact lenses that are daily, weekly, fortnightly, monthly and etc. Contact lenses are also divided into 2 main categories that are deemed the best ones: soft and hard lenses.
Soft Contact Lenses
Soft lenses fit perfectly into the eyeball and their presence is almost unnoticeable to the user. Soft lens varieties are used to correct visual defects and they are more comfortable than hard lenses because they fit exactly in the eyeball. The soft lens types can be used to correct visual defects such as myopia, hyperopia, astigmatism and presbyopia. Since the soft contact lens fits very well to the eyeball, the probability of small dust particles getting to the eye is very small. Soft lenses are produced from special materials to maintain the moisture content of the eye and to keep the surface of the lens constantly moist. In addition to all other features of soft contact lenses, the most important advantages are that they allow free flow of oxygen, that is, they are permeable to oxygen and consequently protect the eye health.
Daily soft lens varieties may be a bit costlier since they need to be disposed of at the end of each day, but they are the most preferred soft lens types in Europe because they eliminate the need for cleansing and waiting in the lens solution. Lens users can choose daily lenses with daily soft lenses next to their monthly lenses, for example, to avoid losing or losing monthly lenses, for example when traveling, sports or on very busy days.
There are also a variety of soft lenses for longer use, and a range of lenses that can be used for a week or a month without removing them at night. There are also varieties of coloured soft lenses that are used for cosmetic purposes.
Toric lenses are the best for those with astigmatism
The new soft toric lenses are very flexible; the toric lens works with the principle that two upright curves within the lens break the light differently. Curves on the soft toric lens must fit into the appropriate places in the eye to correct the astigmatism
Multifocal lenses are one of the best contact lenses
Multifocal lenses have multiple focal points, divided into concentric circles, the closer you get to the centre, and the more the lens adapts to distant vision, the further away you are from it and the closer the focus distance.
Rigid gas permeable contact lenses
They are also called gas permeable lenses because they allow the passage of oxygen to the cornea. They are used in high astigmatism because they do not take the shape of the cornea. It is used to increase the visual acuity of keratoconus disease, where the cornea is erecting, forward, and sharp, and the central part of the cornea is thinned. Although the visual acuity and visual quality of these lenses are quite good, the longevity time is longer than the other lenses.
Having the best contact lens depend on the medical condition of your eyes
Do not stress over having the best contact lenses – the best one is the one you need. It is important to clarify that the prescription for contact lenses may be different from prescription eyeglasses. For example, if you are astigmatic, the indications will be different because glasses are designed with lower degrees. Another example, if you are nearsighted or farsighted, the indications are different, because the distance between your eyes and the lenses is not the same as the distance between your eyes and the spectacle lenses.
