Computer Vision Reading Eye Glasses
Computer Vision Symptoms: headaches, tired eyes, burning eyes, watering eyes, itching eyes, dry eyes, double vision, blurred vision, eye fatigue, eye strain, bloodshot eyes, sore eyes, irritated eyes, and eye pain
- – The power added to the distance prescription to provide for near vision
- – a clear thin film of a certain thickness that when applied to a lens will absorb light that would have been reflected.
- – a clear tough coating applied to plastic lenses to reduces scratches.
- – a condition of the eye where the meridians of the eye are not the same causing a spot of light to appear as a streak
- – the visual system of the eye has been broken down into 360 degrees like the numbers on a clock. These degrees are called axis and are used when prescribing astigmatism where the axis do not contain the same power.
- – the thickest part of a prism and used to indicate the location of the prism when part of the prescription.
- – the curve on the back side of a lens. In glasses it allows for clearance of the lashed when blinking, and in contact lenses it has an effect on the fit of the lens on the eye.
- – the distance between eyeglass lenses to provide room for the nose.
- – a clouding of the intraocular lens used to change focus.
Computer Vision Syndrome (CVS)
- – A group of eye and vision problems experienced during computer use. Symptoms include eye fatigue, burning/irritated eyes, double and/or blurred vision, as well as, back, shoulder and neck pain.
- – the process of turning the eyes inward to fixate on a nearby object.
- – the difference between the greater and lesser power of the major meridians of the eye in astigmatism.
- – a measure of the refractive power of a lens as relates to a meter of distance.
- – The horizontal measurement of a lens in millimeters.
- – otherwise known as farsightedness where the focuses beyond infinity when at rest
- – that part of the energy spectrum between 760 and 3000 nm. known as the heat ray and outside the visual spectrum.
- – surface coatings placed on a lens that filters the light going through it.
- – known as flash coating which is applied to the front surface of the lens to give a mirror effect.
- – otherwise known as nearsightedness where the eye focuses inside of infinity when at rest.
- – that portion of the eyeglass that rests on the nose.
- – having to do with the eye and vision.
- – short for oculus dextrous which is latin for right eye.
- – short for oculus sinister which is latin for left eye.
- – a type of lens which gets dark when exposed to light.
- – light that vibrates in only one meridian such as reflected glare, instead of all meridians such as found with normal light.
- – a condition where the eye loses it’s ability to change focus from distance to near.
- – a lens where one edge is thicker than the opposit edge.
- – the distance between the visual axis of the two eyes.
- – the difference between the base curve of the front and back curve of the lens.
- – the distance from the hindge of the glasses to the top of the ear in inches.
- – that part of the energy spectrum between 200 and 380 nm. and outside the visual spectrum.
- – the distance between a computer screen and the eye which is generally 20 to 28 inches.
- – that part of the energy spectrum between 380 and 760 nm visible to humans.
