What is the difference between acuvue oasys for astigmatism and acuvue advance for astigmatism?

What is the difference between acuvue oasys for astigmatism and acuvue advance for astigmatism?

Material: Advance: silicone hydrogel material (galyfilcon a) with hydraclear wetting agent
oasys: silicone hydrogel material (senofilcon a) with hydraclear plus wetting agent (less friction), slightly higher uv-a blockage
oasys are more comfortable for some, but also cost more. ...Read more

Astigmatism (Definition)

An eye condition that causes blurry vision because the eye is unable to focus light to a point and thus unable to produce a sharp ...Read more

How does acuvue advance for astigmatism differ from acuvue toric lenses?

How does acuvue advance for astigmatism differ from acuvue toric lenses?

Toric contact lens: Toric contact lenses correct astigmatism. Acuvue makes 3 astigmatism correcting lenses: acuvue advance for astigmatism, acuvue moist for astigmatism (a 1 day lens) and acuvue oasys for astigmatism (more for dry eye patients). All are toric contact lenses. ...Read more

Is acuvue oasys good for astigmatism?

Is acuvue oasys good for astigmatism?

It's very popular: Acuvue oasys for astigmatism is a very popular contact lens used to correct astigmatism. Soft contacts used for astigmatism must remain in a constant rotational position on the eye. This contact's design has been more successful at this than some older types. Although it doesn't work for everyone, it is among several very good options for astigmatic lenses. ...Read more

What is the difference between regular, irregular astigmatism?

What is the difference between regular, irregular astigmatism?

Correctability: Regular astigmatism is a refractive error produced when your eye generates an image as if the light rays passed through a regular shaped glass football. Irregular astigmatism is when the football is not shaped regularly, e.g. One end is fatter than the other. It is very difficult to fully correct vision by any technique in cases of irregular astigmatism; contacts are useful. ...Read more

What is the difference between astigmatism and short-sightedness?

What is the difference between astigmatism and short-sightedness?

Oval eye shape: Refractive errors require either plus (farsighted) or minus (nearsighted) glasses + an extra amount if the eye is oval in shape (astigmatism). These are called refractive errors and can be corrected with glasses or contacts. Short sightedness is another term for myopia which uncorrected usually allows for good vision at near and blur at distance. ...Read more

What is The difference between keratoconus And severe astigmatism?

What is The difference between keratoconus And severe astigmatism?

Keratoconus is: Progressive disease of the cornea in which the normally dome shaped cornea thins and begins to bulge into a cone-like shape. This condition needs to be monitored and possibly treated to prevent long term visual disability. Astigmatism is a refractive error, therefore it is not an eye disease it is an error in the focusing ability. Astigmatism is treated simply with glasses, contacts or surgery. ...Read more

What is the difference between double vision and astigmatism?

What is the difference between double vision and astigmatism?

Appearance: Double is usually two images separate either horizontally, vertically, or obliquely. Not necessarily blurred unless also uncorrected refractive error. Astigmatism is a refractive error causing slight distortion of an image in one direction. Depends on amount. ...Read more

What's the difference between myopia and astigmatism. Can you have astigmatism without having myopia?

What's the difference between myopia and astigmatism. Can you have astigmatism without having myopia?

Two separates: Myopia is very near vision and need for glasses beyond a foot or so. You may can read when very close to you but cannot see beyond arms length. Astigmatism is an irregular contour of the cornea and causes waviness and blurring in the pattern of sight. You can have one without the other. Your eye care professional can examine you and correct most of these problems. Seeing it clearer? ...Read more

Describe difference is between regular and irregular astigmatism?

Describe difference is between regular and irregular astigmatism?

Eye curvature: Lenses used by eye doctors to determine your need for refraction and eyeglasses, are based upon regular curves which for astigmatism optically are called toric. If the astigmatism is due to scar and some intrinsic disease like keratoconus, then the curve does not follow the toric pattern and the astigmatism is termed irregular. This may require a hard lens for correction. ...Read more

What are the differences between astigmatism & myopia?

See below: Myopia, or nearsightedness, is usually caused by the eye being longer than the focusing power. Astigmatism is when the cornea (the front window of the eye) is not spherical - more like a football than a basketball. ...Read more

Are the astigmatism axis read counterclockwise or clockwise? On both eyes? Is the same to have 4 or to have 176? Or is there a 8 degree difference?

Are the astigmatism axis read counterclockwise or clockwise? On both eyes? Is the same to have 4 or to have 176? Or is there a 8 degree difference?

Read on 180 axis: Think of astigmatism as a foot ball type oval. The orientation of the points of the football determines the axis which can be horizontal (180 degrees) or vertical at 90 degrees or anything in between. It is read clockwise with no overlap so there is no set of numbers higher than 180 degrees. ...Read more

I wear acuvue advance lens bc 8.7. I want to try acuve oasys bc 8.4 and 8.8 which 1 would be good fit? For me which one would the best fit?

I wear acuvue advance lens bc 8.7. I want to try acuve oasys bc 8.4 and 8.8 which 1 would be good fit? For me which one would the best fit?

8.8: 8.8 is closer to what you are wearing and will most likely work well. Contact lenses should give you good vision and proper comfort, so if the 8.8 does this you will be doing well. ...Read more

How bad is my astigmatism? O.D. -.5/+1.25/+175. O.S. -.5/+1.75/+172

How bad is my astigmatism? O.D. -.5/+1.25/+175. O.S. -.5/+1.75/+172

Good/Bad in the eye: Of the beholder. Astigmatism simply means the focusing of the eye is not equal all angles around the central line of sight; more curvature one way than 90 degrees around. The +1.25 & +1.75 values in the ophthalmologist's Rx for correction is the astigmatism correction in diopters (1 = the curvature needed to focus parallel light rays to a point 1 meter away). Values >3-4 diopters=fairly high. ...Read more

Can you tell me in astigmatism, he wrote od 43.75 43.00 os 43.50 42.75 does anyone understand these numbers?

Can you tell me in astigmatism, he wrote od 43.75 43.00 os 43.50 42.75 does anyone understand these numbers?

Curvature of cornea: These numbers are diopter power readings of the surface of the cornea. These measurements can be taken with a Keratometer or Corneal Topographer. Tha amount of corneal astigmatism is the difference between the two numbers for each eye. This does not indicate how much astigmatism correction would be in your glasses as there are other factors that can contribute to astigmatism. ...Read more
