Everyone wears contact lenses for different reasons, but most people wear them to help see clearly. Over the eyes, since when contact lenses were introduced, there has been manufacturing of lenses to suit all kinds of eye issues.
In fact, there are now more types of contact lenses and lens options than there were previously. The majority of people have no problems wearing contact lenses. You may have to try a few different types before locating the perfect pair. If you’ve tried contacts before but stopped due to pain or poor quality, it’s time to give them another shot.
In this blog post, I’ll share contact lens brands suitable for various eye difficulties, including correction, tear production, prescription, lifestyle, and more as well as the different contact lenses online that are popular as well.
Soft Contact Lenses
The most common type of contact lens is soft contact. They account for more than 85% of all contact lenses sold. Soft plastic polymers and water make up traditional soft contact lenses. These lenses allow oxygen to reach the cornea through the lens material.
The majority of people find soft contact lenses to be quite comfortable. Soft contacts have the benefit of allowing people to adapt to them quickly. Soft lenses are available in various prescriptions and designs to suit your budget and needs.
Some prescriptions do not provide the same visual acuity as gas permeable lenses or glasses. Your eye doctor can assist you in determining which design is ideal for you.
Disposable Contact Lenses
Soft contact lenses that are discarded on a daily, weekly, bi-weekly, or monthly basis are known as disposable contacts lenses. Protein deposits do not form when replacement is done regularly.
Deposits can have an impact on vision, comfort, and eye health. Compared to standard soft lenses, these lenses are more convenient and low-maintenance.
In order to avoid eye infection, it’s critical to replace disposable contacts as directed. Most prescriptions can be filled using disposable contact lenses.
Tinted or Cosmetic Contact Lenses
Soft contact lenses that affect the colour of the iris for some individuals are known as tinted contact lenses (the coloured part of the eye). These lenses come in a variety of fun colours and patterns. They can alter the appearance of your eyes subtly or dramatically. They aren’t suitable for all medications and aren’t recommended daily use.
Hard Contact Lenses
Hard polymethyl methacrylate contact lenses were widespread before developing soft contact lenses. They prevented oxygen from reaching the cornea and frequently caused it to bulge. As a result, hard contact lenses have become outdated.
Rigid Gas Permeable Lenses
Rigid Gas Permeable (RGP)—or simply Gas Permeable (GP)—lenses are frequently confused with traditional lenses. People’s memories of the old hard contact lenses are long gone.
RGP lenses are malleable, soft, and let oxygen pass through the cornea. Traditional soft contact lenses do not enable as much oxygen to reach the cornea as gas permeable lenses. Because they are stiff, they do not change shape when you blink or move your eyes.
It implies that they provide clearer vision than soft contacts. They last a lot longer than soft lenses. Proteins and lipids do not cling to them as they do to soft lenses since they do not contain water. RGP lenses are available in a variety of bifocal and multifocal contact lenses configurations.
The most significant disadvantage of RGP lenses is that they require patients to adjust. They are not as comfy as soft lenses right away. Patients must adjust to RGP lenses for 3 to 4 days. They must be worn regularly (albeit not every day). Because they are smaller, they are easier to remove from the eye than soft lenses.
Toric Contact Lenses
Astigmatism can be corrected using toric contact lenses. They come in both soft and gas-permeable varieties. There is a vertical power and a horizontal power in these lenses.
Toric contact lenses have a lower weight at the bottom, which allows them to centre themselves correctly on the eye. Fitting toric lenses are more complicated. They usually demand the patient to spend more time determining their comfort level. The doctor may be required to provide additional fitting assistance.
Bifocal Contact Lenses
Like bifocal glasses, bifocal contact lenses have multiple powers. This lets an individual see clearly in both close and far-fields. Both soft and gas permeable versions of these lenses are available.
Monovision correction is another option for bifocal contacts. One eye is utilized for distance vision, while the other is used for near or reading vision using these lenses. Both of these lens types necessitate a longer fitting time from the doctor. Patients must learn to use one eye depending on the distance being viewed.
Contact lenses that are replaced every other week are known as bi-weekly contact lenses. Bi-weekly contact lenses, often known as 2-week disposable contact lenses, strike a compromise between low maintenance and comfort.
Bi-weekly contacts differ from conventional contacts in a number of ways, the most notable of which is the length of time you can wear them before discarding them.
You can keep bi-weekly contacts for two weeks before discarding them. After a month, monthly contact lenses are required. You discarded the lenses, and daily contacts should be discarded after a day.
Both eyes do not have the same prescription. One can be for distance vision, while the other will be for up-close vision. It may take some time to adjust to this.
Each eye acts independently. This makes it more difficult for them to collaborate. It’s possible that you have issues with depth perception. It may be not easy to drive as a result of this. To allow one eye or the other to see well, you may need to adjust your gaze more frequently.
Another monovision alternative is wearing a bifocal lens in one eye and a single-vision lens in the other. This makes driving more convenient.
Hybrid contact lenses
Hybrid contact lenses combine the wearing comfort of soft or silicone hydrogel lenses with the crystal-clear optics of gas permeable lenses to create hybrid contact lenses.
A hard gas permeable centre zone is surrounded by a “skirt” of hydrogel or silicone hydrogel material in hybrid lenses. Although these benefits, hybrid contact lenses are only worn by a tiny percentage of people in the United States, possibly because they are more difficult to fit and replace than soft or silicone hydrogel lenses.
PMMA lenses are composed of polymethyl methacrylate (PMMA), a clear stiff plastic material used as a replacement for glass in shatterproof windows and is sold under the brand’s Lucite Perspex and Plexiglas.
Although PMMA lenses have great optics, they do not transport oxygen to the eye and are difficult to adjust to. These (now obsolete) “hard contacts” have largely been replaced by GP lenses and are no longer often prescribed.
These lenses alter your appearance but do not correct your vision. Coloured contacts and lenses can transform your eyes into vampires, animals, and other figures.
They’re also utilized to conceal some visual issues that are either present at birth or result from trauma. Decorative contacts require a prescription, even if they do not correct eyesight.
These lenses must be handled like prescription contacts to avoid severe eye infections. This entails cleaning them as advised regularly.
