Can You Wear Contact Lenses?

Everyone can wear contact lenses, but the majority of the people out there who need glasses generally wear contact lenses. However, contact lenses are not suitable for those individuals who have a specific vision problem or are prone to specific vision problems. While it is perfectly safe to wear contact lenses, they can still damage your eyes if you wear them for too long or do not follow the instructions carefully.

 There are two primary safety aspects regarding the use of contact lenses, first is the flow of oxygen in the eyes, and the next is properly cleaning and disinfecting of the contacts and the case.

The Right Flow Of Oxygen

As the contact lenses cover the entire cornea, the amount of oxygen that reaches your eyes decreases. However, an adequate supply of oxygen is essential to keep the eyes healthy. According to the contact lenses experts, one can limit the oxygen deprivation because of the contacts by taking certain precautions.

Go for the modern contact lenses made of much softer material that allows a higher transmission of oxygen. Another option is to go for the Gas permeable contacts that cover less part of the cornea.

Proper Cleaning Of The Contact Lenses

 As infection-causing agents tend to accumulate in the contacts, it is very essential to follow a strict routine for cleaning and disinfecting. As the lenses get older, they tend to attract more deposits on the front and back surfaces of the lenses. Although the percentage of people getting those eye infections is small, the consequences can be devastating. One can minimize those risks with a proper cleaning and disinfecting schedule for the contacts.

Contact Lens Material

  • Soft lenses – The soft contacts are made from hydrogels, which is water-containing plastic. These lenses are very thin and comfortable to wear.
  • Silicone hydrogel lenses– The advanced soft contact lenses are much more porous and pliable than the regular soft lenses and allow more oxygen to reach the cornea.
  • Gas permeable lenses — The rigid contact lenses are permeable to oxygen and are more porous. These are also called GP or RGP lenses.
  • Hybrid contact lenses– These contacts are designed to offer maximum wearing comfort and offer the combined property of crystal-clear optics of gas permeable lenses and the softness of silicone hydrogel lenses.
  • PMMA lenses – The polymethyl methacrylate or PMMA lenses are made from a transparent plastic material that is rigid but carries excellent optics. However, it can be difficult to adapt to these lenses as they do not transmit oxygen.

Majority of the contacts prescribed today include silicone hydrogel lenses, followed by soft lenses and gas permeable lenses. PMMA lenses are hardly prescribed or advised.
