Is your eye doctor bandying about the words nearsighted or farsighted? Talking about corrective lenses and asking if you want contact lenses? If your eye doctor has mentioned corrective lenses and asked about contact lenses chances are you have eye problems severe enough that you have to have contact lenses or glasses all the time. Most eye doctors will not suggest contact lenses for some one who needs corrective lenses for driving or reading or even for a low prescription. Contact lenses will change how you view corrective lenses. A little background on the contact lenses of today is below.
With the aim to make contact lenses more convenient to use, polymer-based substance were utilized to produce soft contact lenses. Otto Wichterle has just made himself popular with his works on soft lenses that are made of hydrogel. The success of the invention has made the manufacture of soft contact lenses through out the world. They are proven to be more convenient to use compared to the first versions of contact lenses.
Glasses tend to create reflection problems with lights and sunlight so many people tend to want contact lenses, but you may not realize the affects contact lenses can have on your eyes. Contact lenses unlike glasses can hinder the oxygen flow to your eyes and create blood clots, that’s why most eye doctors will wait until you have a substantial prescription before suggesting contact lenses and even then they will worry about the oxygen flow, especially if you are considered legally blind without corrective lenses because the weight of the contact lenses like glasses becomes a little heavier.
We have many options when you are considering contact lenses. You may decide you want color contact lenses or you may need a correction for an astigmatism. An astigmatism creates a deficit in vision that cannot be corrected with just any contact lens. Astigmatism correction will take away the blurriness created by the disorder. Without a weighted lens you will still have blurry vision if you have an astigmatism. Most doctors will not seek correction for this problem if it is mild because the Toric contact lenses tend to be heavier. If you still suffer blurry vision with contacts you can ask your eye doctor about correcting for the astigmatism you have.
Contact lenses are all about comfort. You want your eye to be satisfied with having a corrective lens on it. The soft contact lenses are more comfortable than their forbearers. When you have contact lenses you need to establish proper care in order to keep your eyes healthy and bacteria free. You also need to wear them for the time allotted and no longer because of protein build up on the lenses. Protein builds up on the contact lens after being worn for a while and unless you have gas permeable lenses you will need to dispose of the contacts after the allotted time. Ask your doctor about the proper care of contact lenses.
