Key Differences in Lens Design

Optical Spherical Glass Lens Structure

Spherical lenses are used in many devices. They have a simple shape. The surface curves the same way everywhere. This makes them easy to make and use. There are different types of spherical lenses. Each type changes light in its own way.

Spherical lenses have the same thickness all over. This can cause problems like blurry edges or strange shapes. One spherical lens cannot fix every optical problem. Wuhan Star Optic Technology Co., Ltd uses strong glass and careful checks. This helps each lens work well in your device.

Aspherical Lenses Structure

Aspherical lenses look different than spherical lenses. Their curve changes from the center to the edge. This special shape helps fix problems that spherical lenses cannot.

· Aspherical lenses have a changing radius of curvature. This lets the lens bend light in a better way.

· The thickness of aspherical lenses is not the same everywhere. This helps them focus light more exactly.

· Aspherical lenses give sharper pictures and a bigger view. They lower distortions and make images clearer.

You see aspherical lenses in fancy cameras and medical tools. Their special shape means you need fewer lenses in your device. This makes things lighter and smaller. Wuhan Star Optic Technology Co., Ltd uses smart machines and skilled workers. Their aspheric lenses meet tough rules. You can trust these lenses for jobs that need clear pictures and high accuracy.

Tip: Pick aspheric lenses for the best pictures and less distortion. Spherical lenses are good for easy jobs and cost less.

Optical Performance Comparison

Spherical Lens Aberrations

Spherical lenses can make your vision look strange. These problems are called optical aberrations. Spherical aberration happens when light at the edge and center focus in different spots. This can make things look blurry or cause glowing rings around lights at night.

Spherical lenses can also make images less sharp and lower contrast. These problems are worse in dim light or when you need to see well. The table below shows how often spherical aberrations happen in different groups:

People with high myopia have higher numbers. The chart below shows how often spherical aberrations happen by axial length in the high myopia group:

Spherical lenses can make it harder to see details. You might see more glare or less detail, especially when you need to see clearly.

Aspherical Lenses Clarity

Aspherical lenses have a special shape that fixes these problems. Their curve changes from the center to the edge. This helps all light rays meet at the same spot. You get sharper images and better vision.

Aspherical lenses can lower spherical aberrations by up to half. You may also see 5% to 10% better contrast sensitivity with aspheric lenses. This means you can see details better, even in low light or at night.

The table below compares how spherical and aspherical lenses work:

Aspherical lenses give you better results in many ways. They help you see more clearly and with less effort. You will notice this when driving at night, reading, or using devices.

· Aspherical lenses lower spherical aberrations by about half.

· Aspheric lenses make contrast sensitivity 5% to 10% better after surgery.

· You get sharper images and better vision with aspherical lenses.

Tip: If you want the clearest images and best vision, pick aspherical lenses. They help you see details and colors better, even in hard situations.

Cost and Manufacturing

Spherical Lenses Affordability

Spherical lenses usually cost less than aspherical lenses. Their simple shape makes them easy to make. Factories use quick machines and basic tools for these lenses. This helps keep prices low for buyers.

· Spherical lenses need fewer grinding and polishing steps.

· New technology helps companies make thinner, lighter spherical lenses. This saves materials.

· Better coatings, like anti-reflective layers, help more light pass through. They also make lenses last longer.

· Scratch-resistant coatings add value but do not raise the price much.

You can use spherical lenses in cameras, glasses, and research tools. Their lower price makes them good for projects that do not need special shapes or high accuracy. Wuhan Star Optic Technology Co., Ltd uses strong glass and advanced coatings. This gives you good light transmission and long-lasting lenses.

Aspherical Lenses Production Complexity

Aspherical lenses have a more complicated design. Their curve changes across the surface. Making these lenses takes more time and skill. Special machines and trained workers are needed. This makes them cost more.

· Aspherical lenses need advanced grinding and polishing for the right shape.

· High-precision tools keep the lens accurate. This can mean more pieces get rejected.

· Smaller production runs mean less savings than with spherical lenses.

· The surface of aspheric lenses does not have one curve. Each part needs careful work.

Aspherical lenses often use new methods, like precision glass molding or injection molding. These help lower costs and keep light transmission high. Wuhan Star Optic Technology Co., Ltd uses advanced materials and strict checks. Every aspheric lens meets your needs for clear images and good performance.

Note: If you want the best light transmission and sharp images, aspherical lenses are worth the extra money. For simple jobs, spherical lenses give you good value and reliable results.
