Jaeger 2 Test Card The Jaeger near point eye chart is used for reading up close and for determining your near vision. When reviewing the chart, you will see the notation 2 above the paragraph with the smallest text and each progressive paragraph of larger text is noted with an increase in the number. What does a Jaeger chart test?
The Jaeger chart is an eye chart used in testing near vision acuity. It is a card on which paragraphs of text are printed, with the text sizes increasing from 0.37 mm to 2.5 mm. This card is to be held by a patient at a fixed distance from the eye dependent on the J size being read.
What is the normal Jaeger test result?
For near vision, 14 / 14 (35 / 35) is normal, with 14 in. (36 cm) being the normal distance for reading. A Jaeger number relates to the size of text you could read on the Jaeger chart. The higher The J number, the worse near vision. What is Pelli Robson chart?
Purpose : The Pelli-Robson (PR) chart measures a patient’s contrast sensitivity (CS) by finding the lowest contrast letters he/she can read correctly. Pelli et al (1988) recommended testing at 3m, which places our 4.8 cm letters at 1.0 logMAR, but suggested closer distances for low-vision patients.
What is Jaeger number?
Jaeger notation, also commonly used, assigns each line on the card a single arbitrary numeric value corresponding to a Snellen value. For example, Jaeger 2, abbreviated J2 when recording in the patient’s chart, is equivalent to the 20/30 Snellen distance- equivalent line on the near vision card. How do you read a Jaeger test?
The Jaeger Eye Chart is used for reading up close and determining visual acuity, or general visual performance. When reviewing the chart, you will see the notation 1 next to the paragraph with the smallest text and each progressive paragraph of larger text is noted with an increase in the number.
Frequently Asked Questions(FAQ)
How do you score a Jaeger chart?
Jaeger scores (designated J1, J2…) are sometimes used to rate near acuity. However, these values are not standardized for size or test distance. Confusion can result from their use. … Visual Acuity and Eye Charts.
| Jaeger | Snellen | Point |
|---|---|---|
| J1 | 20/25 | 4 |
| J2 | 20/30 | 5 |
| J3 | 20/40 | 6 |
| J5 | 20/50 | 8 |
What is the meaning of 6 6 in eye test?
6/6 vision describes being able to see at 6 metres what an average person can see at 6 metres. While 20/20 vision describes the same ability, but at 20 feet rather than 6 metres.
Is 8.5 eyesight bad?
Generally, the further away from zero (+ or -), the worse the eyesight. A number between +/-. 025 to +/-2.00 is considered mild, a number between +/-2.25 to +/- 5.00 is considered moderate, and a number greater than +/- 5.00 is considered severe. Eye prescriptions can change over time.
Is minus 3.5 eyesight bad?
If your number is between -0.25 and -2.00, you have mild nearsightedness. If your number is between -2.25 and -5.00, you have moderate nearsightedness. If your number is lower than -5.00, you have high nearsightedness.
What is the meaning of 6 6?
What is Rosenbaum eye chart?
The Rosenbaum card is the most widely used handheld card for measuring near visual acuity. It was developed by Dr. J. George Rosenbaum of Cleveland, Ohio, for testing vision at the bedside of patients after cataract surgery.
What are errors of refraction?
What is a refractive error? A refractive error is a very common eye disorder. It occurs when the eye cannot clearly focus the images from the outside world. The result of refractive errors is blurred vision, which is sometimes so severe that it causes visual impairment.
What line is 20 40 on eye chart?

What is Bailey Lovie testing?
For many years, the Bailey-Lovie chart set has been a proven tool for determining distance visual acuity at normal and low contrast. The Bailey-Lovie chart features a stringent logarithmic progression of optotypes.
What does LogMAR 0.2 mean?
The term LogMAR is an acronym for the Logarithm of the Minimum Angle of Resolution. … The letter size is described in LogMAR units where LogMAR 0.00 is equivalent to 6/6 (20/20) and LogMAR 1.00 is equivalent to 6/60 (20/200).
How do you use a LogMAR chart?
- Ask patient to read down chart with one eye covered.
- Note how many letters are read correctly until none of the letters on a line are.
- read correctly.
- Read off vision score from chart.
- Repeat with pinhole if the vision is worse than 0.2.
- If logMAR vision is worse than 1.0, retest at 2m or 1m (see over page)
What is vision chart?
A Snellen chart is an eye chart that can be used to measure visual acuity. Snellen charts are named after the Dutch ophthalmologist Herman Snellen, who developed the chart in 1862. Many ophthalmologists and vision scientists now use an improved chart known as the LogMAR chart.
How many types of Snellen charts are there?
These include Snellen Chart, LogMAR Chart, Jaeger Chart, E Chart, and Landolt C Chart. These charts are described thoroughly below. It was developed by Dutch ophthalmologist Herman Snellen in 1862 and thus is named after him. Snellen used symbols based on a 5×5 unit grid while developing the charts.
What is near vision chart?
Near vision is measured using a small handheld chart that has paragraphs of text that is smallest at the top and largest at the bottom. These are of a standard size and ‘normal’ near vision is known as N6, with ‘N’ referring to near and the ‘6’ referring to the size of the letters; N5 is better than N8, for example.
How do you read a Rosenbaum chart?
Ask the patient to say each letter or read each word on the line of smallest characters that are legible on the card. Record the Va for the right eye according to the accepted notationmethod. Repeat the process for the left eye and then with both eyes viewing the test card and record the Va.
What is J1 in eye test?
The J1 paragraph on a Jaeger card is usually considered the near vision equivalent of 20/20 vision on a distance eye chart. On some Jaeger cards, the J1+ paragraph is the 20/20 equivalent.
What is perimetry in ophthalmology?
Perimetry is the systematic measurement of visual field function (the total area where objects can be seen in the peripheral vision while the eye is focused on a central point). The two most commonly used types of perimetry are Goldmann kinetic perimetry and threshold static automated perimetry.
How do you do a confrontation test?
Confrontation visual field testing involves having the patient looking directly at your eye or nose and testing each quadrant in the patient’s visual field by having them count the number of fingers that you are showing. This is a test of one eye at a time.
How good is my depth perception?
If your depth perception works well, you should see two slightly faint, slightly blurred images of your finger on both sides of the tennis ball. You should also be able to make out the complete image of the ball. Focus your vision, next, on your finger.
What is Amsler grid chart?
Introduction. The Amsler Grid is a square-shaped grid used to detect or monitor metamorphopsia or scotoma involving the central visual field in various disorders of the macula and optic nerve head.
What is a good eyesight score?
20/20 Visual acuity of 20/20 is considered “perfect vision” because no aids are required to see better, but people can have better than 20/20 vision.
What does N5 mean in an eye test?
N5. Sphere (Sph) represents the amount of dioptric power required to correct your long or short sightedness. If the number is positive (+) you are longsighted ( hypermetropic), if it is negative (-) you are shortsighted ( myopic).
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
