Alert! Vision Presbyopia;Difficulty-Accurately In Distances?

Alert! Are You vision Presbyopia-Difficulty In Driving?

A normal eye test may not detect this common age-related condition.eye test with a 20/20 score “perfect vision” doesn’t give you a true or complete assessment. Alert! Are You vision Presbyopia-Difficulty In Driving? Identifying rows of black letters on the white background your eye doctor measure your visual acuity.  struggling reading or seeing things up close or having difficulties transitioning from near to far back to near again or you’re holding things way out here and your arms just aren’t long enough well you may have a condition called presbyopia  Alert! Are You vision Presbyopia-Difficulty In Driving? Most common age-related conditions.

Three symptoms -signs of more serious eye-health. 1-Presbyopia 2-Loss of contrast sensitivity 3-Dry eye- 4- Glaucoma, a progressive disease that damages your optic nerves

Stepping off an unmarked curb or seeing steps clearly

TESTING-IMPORTANT ROLE– Glare accentuates contrast sensitivity TEST(glare test”)

Contrast sensitivity is increasingly recognized as an essential factor in your quality of visions Some sort of optical correction to see things up close as they get older and that’s from this condition called presbyopia This is a condition where a structure inside the eye starts to change makes things up close more difficult to see

AGE FACTOR;

This affects starting around mid forties some little bit earlier maybe late 30s and everybody before the age of 55 getting into their 60s. Clear structure called crystalline lens and young children lens is clear but it is very thin, flexible. Every year of life as we get older this lens gets thicker and thicker have you ever heard that every seven years the cells of body regenerate and you have much an entirely new body well not entirely true.Lens of the eye has the exact same cells that you were born.The lens grows an extra layer thick every year of life kind of like the rings on a tree.

Following adjustments: Nearby objects clearly, –

Convergence of the two eyes – this is to make sure the object is focused on the fovea of each retina. Failure of doing so , when the eye muscles are weak – would result in double vision. This is because object is focused on different parts of the two retinas and the brain sees two images. – Constriction of pupil – this is to reduce spherical aberration. Spherical aberration occurs when light rays hit the edge of a lens and produce blurriness. Alert! You vision Presbyopia;-Difficulty in accurately determining distances

TREATMENT;

If presbyopia’s your only vision problem thenlyou need a pair of reading glasses, But if you already wear specs, you’ll need to switch your lenses to bifocals, in which the top of the lens is corrected to treat distance vision, while the bottom helps you see things close up; or opt for progressive lenses, which have gradual focal changes. Constricted pupil allows light rays to enter the lens in the center where they are best refracted. – Accommodation of the lens – ciliary muscles contract to make the shape of the lens more convex. This increases the optical power of the lens. It now can converge the divergent light rays onto the retina.

you wear contacts, you have two options:

1-Lenses, which correct one eye for seeing at a distance other for close-up vision, 2- Multifocal lenses In different parts of the lens are set at different powers.The eye becomes stiffer as get older. There’s nothing can do and because it’s the lens itself that gets stiffer rather than muscles that change shape of the lens weakening, you can do to stop you reeding reading glasses.

If your presbyopic and you need glasses for reading you will find if you look up in the distance through those glasses your vision is blurry. That’s why you see people peering over the top of their glasses . Common Presbyopia happens lens inside the eye becomes stiffer as we get older. That’s why you see people peering over the top of their glasses like that. Alert! Vision Presbyopia;-Difficulty Accurately Determining Distances?

CONCLUSION;

Presbyopia- the lens inside the eye becomes stiffer as we get older. There’s nothing you do and because it’s the lens itself that gets stiffer rather than the muscles that change the shape of the lens weakening, you can do to stop you needing reading glasses. If your presbyopic and you need glasses for reading you will find if you look up in the distance through those glasses your vision is blurry.There’s nothing you can do that change the shape of the lens weakening. presbyopic need glasses for reading you look up in the distance through those glasses your vision is blurry .Age-associated condition in which the eye loses the ability to adjust to near vision. In presbyopia, the lens loses its flexibility with age and becomes stiff. Prebyopia corrected with convex lenses that converge the light rays slightly before they enter the eye .Alert!

Antireflective (AR) coatings can reduce glare

Tinted lenses can moderate or modulate the amount and quality of light that enters your eyes.

Polarized lenses can eliminate reflected glare
