Convex lenses are best for correcting long sight (hyperopia). These lenses are thicker in the center and thinner at the edges, allowing them to converge light rays and focus them properly on the retina. This helps individuals see nearby objects more clearly while accommodating their vision for distance.

Which of the following is used for long sight?
convex lenses
What lenses would you use for short sightedness and long sightedness?
For short-sightedness (myopia), concave lenses are used to diverge light before it reaches the eye, helping to focus the image correctly on the retina. For long-sightedness (hyperopia), convex lenses are used to converge light before it reaches the eye, assisting in bringing the image into focus on the retina.
How do your eyes focus?
There are inner lenses within your eyes that actually move and change in order to focus from short distance to long distance, this is typically involuntary since no one physical thinks about how the eyes focus in order to actually do so. As you get older your lenses take a shape which are suitable for the range of sight you typically use. In some cases a persons lenses will be ill adjusted and require glasses or contacts in order to see better, as a result of short-sightedness, farsightedness, or astigmatism
What causes short sight and how it can be fixed?
Myopia, or near-sightedness, is caused because the eyeball is too long in relation to the focusing power of the lens onto the retina. This causes the image to be focused at a point in front of the retina rather than on top of it. There are two ways to correct this: corrective lenses (eyeglasses or contact lenses) or surgery.
What travels fastest sight or sound?
Sight by a long shot
Why are lenses useful?
If you are talking about lenses glasses. They help people see long distance or short
What is the difference between long and short sight?
Long-sightedness (hyperopia) means difficulty seeing close objects clearly, while short-sightedness (myopia) refers to trouble seeing distant objects clearly. Both conditions result from abnormalities in the eye's shape, affecting how light is focused on the retina. Glasses or contact lenses can correct these vision issues.
Can eye contacts get stuck?
Contact lenses have come a long way since the glass lenses of old. with the introduction of silicone hydrogel materials contact lenses are less reactive than ever. there is no chemical or physical processes that can fuse the lenses to your eye, and the membrane covering the eye keeps anything from floating around to the side or back of the eye. The latter is less of a concern anyway since the shape of the lenses keeps them centered on your eye. They can become dried out which makes them very difficult to take out.
How long are polycarbon lenses warranted for?
depends...
What does -1.25 mean on contact lenses?
It means you you have a 100 power on your lenses - you cannot see long distances.
What are thermal lenses refering to lenses for paintball masks?
Thermal lenses are built with two lenses put together, which will (in most cases), eliminate fogging altogether. Although the downside is they tend to not last as long, and are more fragile than single lenses.
Does sight have a short vowel sound?
No. The I in sight has a long I sound, as in sigh and site.
