Myopia and hypermetropia are two common refractive eye conditions that affect a person's ability to see clearly at various distances. They are often referred to as nearsightedness and farsightedness, respectively.
Myopia (Nearsightedness):
Myopia is a refractive error in which a person can see objects clearly up close but has difficulty seeing distant objects clearly. It occurs when the eyeball is too long or the cornea (the clear front surface of the eye) is too steeply curved, causing light entering the eye to focus in front of the retina instead of directly on it.
As a result, distant objects appear blurry while close objects can be seen clearly. Myopia can develop during childhood and often progresses over time, especially in teenagers. It is commonly corrected with eyeglasses or contact lenses that have a concave (minus) lens prescription to help shift the focus of light back onto the retina.
Hypermetropia (Farsightedness):
Hypermetropia is a refractive error in which a person can see distant objects more clearly than nearby objects. It occurs when the eyeball is too short or the cornea is too flat, causing light to focus behind the retina instead of directly on it.
People with hypermetropia may experience blurred vision when looking at things up close, and they may have difficulty with tasks like reading or using a computer without correction. Hypermetropia can affect individuals of all ages and may be more noticeable as they age due to changes in the eye's lens elasticity. It is usually corrected with eyeglasses or contact lenses that have a convex (plus) lens prescription to bring the focal point of light forward onto the retina.
Both myopia and hypermetropia are common vision problems and can often be easily corrected with the appropriate eyeglasses or contact lenses.

[@aradhyasehgal7392]

It's known as presbyopia, also called old age hypermetropia (as this defect is commonly observed in elders) and it can be corrected by wearing bi-focal lens.Thank You Sir

[@Nothing-fb6uu]

bi focal lens is used to correct both myopia and hypermetropia. the upper part of bifocal lens is concave lens and lower part is convex lens

[@dnasoha2572]

Such type of defect is called presbyopia and its corrected by Bifocal lenses.. Thank you SIR for making our concepts clear 🙏❤

[@naseeruddin9690]

Presbiopia can be corrected by using bi focal lens or concavo convex lens

[@GlitchGaming2010]

Legends have exam on monday 😂😂😂

[@RufusMusicalChannel1000]

Bi focal lens are used for correction of both myopia and hypermetropia

[@_Eshrath1034]

Hello Sir, Biconcave and Biconvex lenses r used 4 both defect visions hypermetropia and myopia..thnx.. Respected sir u r videos r suchly too amazing and incredible pls continue uploading like this Videos on other topics also like heart etc and Reproduction etc ..❤😊😊

[@Paradise0008]

Sir , can you plz tell me that why did you used the concave lens to diverge the rays of light in the case of hypermetropia?

[@Leticiah-kd7tb]

Thank you sir for all your physics tutorials, they have really changed my grades

[@user-vx2ff5vc6q]

Hello sir Your teaching is really good I loved all your videos Bifocal lens is used for person having both myopia and hypermetropia ( presbyopia)

[@vijayalakshmivemuri8456]

To correct presbyopia we have to use both concave and convex upper part concave lower part convex

[@Aayushk_5002]

Great and easy explanation sir , thanku for this it would obviously help in eaxms .

[@studydreams-ih1my]

Sir does the both lenses form image at the far point (myopic eye) and near point(hypermetropoc eye) which acts like object for the eye lens it forms image on retina ?🤔 Pls solve the query 🙏

[@VinnuKiran]

The condition is called is presbyopia usually seen in old people and they suggested to use bifocal lens

[@basavaraj1684]

Wow..🙌🙌 Amazing video🤩🤩 Please make more practical videos such as this one

[@otiebrown9999]

Positive and negative states of the normal dynamic eye. Depends on your perspective - that might be a mistaken assumption.

[@Tanimols]

Thank you so much,this is going to help me for my exam

[@rithizx]

If a person have both Myopia and Hypermetropia means they can't able to see nearby and far away object... It is known as Presbyopia... It can be corrected with Bifocal lens ❤

[@shivanigarg2680]

To use both lenses concave and convex

[@user-vw2fm7gu9d]

Presbyopia both the concave and convex lens are been used

[@lalli9269]

Dr I was told by an eye specialist that I have a lazyeye(right eye) and can not be fixed...is it true?

[@sriritwikshastry9603]

Bifocal or Progressive Lens is used

[@tiktokworld84]

Can myopia be fixed with eye drops because of recent l went to the eye hospital and l was given systane ultra eye drops and optilyf capsules

[@soumit3752]

Bifocal lenses in used for both myopia and hypermetropia

U are best teacher Thank you so much sir 🙏🙏

Concave lens is used in both conditions

Hii sir, why u kept biconcave lens front of the parallel rays in hypermetropia 6:48 But, why not u kept the biconcave lens before the parallel rays at the time of myopia 3:01 Please answer my question sir

If a preson is suffering from both myopia and hypermetropia, so he should use bifocal lens.

❣️Ask them : 'Who is it that delivers you from dangers in the deep darknesses of the land and the sea, and to whom do you call in humility and in the secrecy of your hearts? To whom do you pray: "If He will but save us from this distress, we shall most certainly be among the thankful?" (6:64) Say: "It is Allah alone Who delivers you from this and from every distress, and yet you associate others with Allah in His divinity."

The person suffering from both myopia and hypermetropia is suggested to wear bifocal lens

[@ranakaushik]

a person having myopia and hypermetropia has to wear a spectacle, which contains both concave and convex lens i.e., both negative and positive power...

[@ManochaAcademy]

Very good Correct! It's called bifocal lens. Now we also get progressive lens.
