Forgetting Spectacles on a daily, not Vision

Contact lenses

Spectacles have been around for quite some time and the use of spectacles has been carried out for the longest time, but along with the new ages of modernization, came a very similar approach to ocular prosthetic devices which was contact lenses.Ever since contact lenses were introduced, they have been repeatedly chosen over spectacles for daily usage because of how convenient and user-friendly they are. Over 150 million people have opted for contact lenses and are satisfied with this choice.

There are three main types of contact lenses such as rigid gas permeable contact lenses, soft lenses, and hybrid lenses. Due to the preferences of people involving lenses over spectacles, the manufacturers also came up with the life duration of lenses that differed from each other.

Lenses were made for single-day use as well as monthly disposable ones which were also termed as daily contact lenses. The lenses were also manufactured with a wide array of colors for people who used them for aesthetical and cosmetical purposes.

 

How are Single-day lenses different than Daily contact lenses?

Single-day lenses are made of materials that cannot withstand a higher duration of oxygen exposure whereas daily contact lens singapore are made up of silicone hydrogels which have a higher oxygen permeability.

The oxygen in the air passes through the lenses resulting in the dissolving in the form of tears that enter the cornea through the lenses, and lenses with lesser oxygen permeability are not advised to be worn overnight.

Therefore, it is mandatory for you to remove the single-day lenses before sleeping, since these lenses can block the cornea resulting in corneal hypoxia or corneal ulcers, which left untreated may result in decreased vision further on.
