Contact Lens

Contact lenses contain synthetic materials. They sit on your eye’s cornea to correct a range of refractive errors. Contact lenses can correct a range of vision problems like long-sightedness, short-sightedness, astigmatism, and presbyopia. A majority of contacts are of the following types:

    ✔ Soft Contact Lenses:

Made of very soft and flexible materials, soft lenses are comfortable to use and conform to the eyes.

  ✔ Hard Contact Lens:

These lenses contain rigid and gas-permeable plastic, which covers the cornea.

When Can Contact Lenses affect your Vision?

Wearing contacts is a functional way to correct your vision. Many people worldwide rely on to wear contacts lenses to correct their vision. However, improper handling of lenses can put you at risk of various conditions which severely affect your vision.

In rare cases, these conditions can cause blindness. As long as you keep pace with your regular cleaning schedule, contact lens won’t pose any threat. It is imperative to follow your optometrist’s instructions to maintain the lenses. Here are some common symptoms associated with improper use of contact lenses.

  • Sensitivity to light
  • Hazy vision
  • Keratitis or inflammation of the cornea

Do You Sleep While You Wear Contact Lenses?

You cannot sleep with your contact lens. If you tend to sleep with contacts, you’ll be at a greater risk of corneal infection. Moreover, the risk of keratitis is higher when you wear contact lenses overnight. The cornea is the only part of your body that receives oxygen from the atmosphere and not the blood supply.

Hence, when we close our eyes while sleeping, we decrease the amount of oxygen to the cornea. Wearing lenses further reduces oxygen supply. To avoid blindness and severe eye infection, avoid sleeping with your contact lenses.    In case you got eye infections you should consult an eye doctor as soon as possible to cure the issue.

You can avoid this problem by buying night and day contact lenses. However, it is important to don’t use them longer then recommended.
