Our Oftalens lenses
Oftalens is an Angolan brand of high quality ophthalmic lenses that adjusts to each person's viewing habits and needs, using the latest Free Form technology – lenses adapted to each prescription. Providing a variety of personalised options, ensuring good vision, visual comfort and easy adaptation.
Monofocal lenses
Monofocal lenses have the same power across their entire surface, which means the prescription is uniform across the entire lens. hese lenses are used in two very common types of vision devices: reading glasses and distance glasses.
What’s the difference between them? In the case of reading glasses, single vision lenses are optimised to provide clear vision of nearby objects and are adjusted to the typical reading distance of a person with presbyopia. objects and are adjusted to the typical reading distance of a person with presbyopia. These lenses are suitable not only for reading books, but also for viewing very small print on devices such as smartphones and tablets. In the case of distance vision glasses, the lenses are defined in such a way as to give the wearer a sharp and clear view of objects that are in the distance – generically, we can say, they serve to compensate for myopia, astigmatism or hyperopia.
Working lenses
Also known as occupational lenses, they provide excellent visual functionality up to 2.20m.
They are individually adapted to meet the specific needs of each person in order to meet the requirements of various working environments. They are ideal for those who have a daily office work routine and need to see clearly at different distances and up close at the same time. However, due to their focus on near vision, they are not recommended for driving and are not a substitute for progressive lenses.
Progressive Lenses
Progressive lenses incorporate different dioptric strengths to cover near, intermediate and distance vision areas, all in a single lens, without any visible transition or dividing line.
The dioptric power is gradual, working seamlessly from top to bottom, allowing for a smooth transition from distance vision to near vision. These lenses provide clear and comfortable vision at any distance and are the ideal choice for correcting problems with myopia, hyperopia and presbyopia. They are ideal for reading, working on the computer, manual tasks or simply for seeing into the distance. Today, these lenses not only offer clear, natural vision, but also allow you to adapt quickly to any distance and direction. In addition, progressive lenses are an excellent option for people with normal vision or astigmatism who are beginning to experience the effects of presbyopia.
Close-up Lenses
Close-up lenses are a category of ophthalmic lenses designed to provide visual comfort and eye relaxation during prolonged use of electronic devices such as computers, tablets and smartphones.
They incorporate technology that reduces eye strain caused by frequent exposure to digital devices. These lenses have a specific correction zone for near vision, optimised for reading distances and the use of electronic devices, making it easier for the eyes to adapt to these activities. In other words, close-up lenses aim to provide a more relaxed and comfortable visual experience, reducing the eye fatigue associated with prolonged use of electronic devices in this digital era.
Stock lenses
Prefabricated in standard sizes and strengths. Mass-produced to meet the most common prescriptions. They generally have limited customisation options, such as a choice of size and strength available in a predetermined set.
They are more affordable and ready for immediate delivery, without the need for additional manufacturing.
Custom Lenses
(Custom-made)Custom-made to meet the user's individual visual correction needs.
They are made based on the user’s specific prescription specific prescription and take into account factors such as the type of frame and the position of the eyes.
They offer greater flexibility in terms of customisation, including advanced options such as multifocal lenses or lenses for correcting high astigmatism.
Typically, they require a longer manufacturing time.
Oftalens lens treatment
Hardening
Anti-scratch treatment is a coating applied to the surfaces of ophthalmic lenses to make them more durable and resistant to scratches and surface damage. This treatment is especially beneficial for those who wear glasses on a daily basis, as it helps to protect the lenses from damage that can occur due to minor accidents, friction or incorrect handling of the glasses.
In short, the anti-scratch treatment is a hardening varnish, an option to improve the durability and visual quality of eyeglass lenses, making them more resistant to scratches and extending the useful life of the glasses. It's a useful addition, especially for those who value the quality and aesthetics of their glasses.
Anti-reflective
Anti-reflective treatment is a coating applied to the surfaces of ophthalmic lenses after anti-scratch coating has been applied to reduce or eliminate unwanted reflections that occur when light falls on the lenses.
Overall, anti-reflective treatment is a great option for improving the quality of vision and the aesthetics of glasses, reducing unwanted reflections, providing a more comfortable visual experience, increasing visual performance, and reducing eye fatigue at the end of the day. It is especially recommended for people who spend a lot of time in environments with intense lighting or who want to achieve a cleaner, more discreet aesthetic from their glasses.
Blue Light
The Bluetech treatment is a remarkable advancement in eye protection against harmful blue light emitted by electronic devices and LED lighting. This treatment applies a special filter to the lenses that blocks blue light, helping reduce eye fatigue, enhance visual comfort, and simultaneously protect the eyes from potential adverse effects of prolonged exposure. The blue light treatment provides a comprehensive solution for your customers who prioritize eye health and visual quality.
Tinting
Tinted lenses are lenses that are used in sunglasses and allow us to see objects clearly because they can be graduated, they present several advantages: Estas lentes, que podem ou não ser graduadas, oferecem diversas vantagens:
-
Ultraviolet Radiation Protection
-
Greater comfort in bright situations
-
Used as a fashion accessory
The harmful effects that UV rays cause are well known (waterfalls, pterygium, which are very common in Angola) and therefore all people who spend a lot of time in the sun (fishermen, farmers, street vendors and the like) should wear glasses with certified tinted lenses Athletes who are exposed to the sun a lot should pay special attention and always wear sunglasses. Excessive brightness causes discomfort and does not allow us to see.
When the brightness is ideal, coloured lenses guarantee us comfort because they can reduce brightness by up to 95%. Tinted lenses can have different absorptions ranging from 20% with almost no drop in brightness to 95% with a high decrease in brightness. Lenses can be uniformly tinted (having the same colour on the entire surface of the lens) or gradient tinted to make it easier to read.
Lens colours can be of any colour, but the most common are grey, green and brown. The colour of the lens can be chosen according to the sport practiced and according to the user’s sensitivity to colour, but the most common is that they are chosen solely based on aesthetic criteria. Blue light, when entering our eyes in large quantities and for several years, can accelerate the ageing of ocular structures, particularly the retina.
It can also affect the circadian cycle, thereby disrupting sleep quality. Since blue light in artificial environments (inside buildings, computers, cell phones, tablets, etc.) is present in a much greater quantity than in natural environments and since we are increasingly exposed to these environments for more time per day, it is necessary to have some eye protection against Blue Light.
Polarised Lenses
Polarised lenses are a special type of ophthalmic lens that are designed to reduce glare and filter bright light. These lenses have a polarising filter that blocks light rays that vibrate in certain directions, only allowing light that vibrates in a specific direction to pass through.
Polarised lenses block intense light reflected from flat surfaces such as water, snow, sand or asphalt. This significantly reduces glare and allows for more comfortable and clear viewing in sunny environments.
Polarised lenses highlight details and improve visual contrast, making colours more vivid and sharp. This is especially useful in outdoor activities such as driving, water sports or snow sports, where clear vision is essential for performance and safety.
In addition to the glare-reducing benefits, polarised lenses also provide protection from ultraviolet (UV) rays, blocking 100% of harmful UVA and UVB rays. This helps prevent eye damage caused by sun exposure, such as cataracts and macular degeneration.
Polarised lenses are available in a variety of materials, colours and designs, offering options to suit individual aesthetic preferences and needs. They are used in sunglasses, prescription glasses or even incorporated into specific sports glasses.
It is important to note that polarised lenses can affect the visibility of certain types of electronic device screens, such as LCD or LED panels. In addition, not all activities or conditions require the use of polarised lenses, and the appropriate choice of lenses must take into account the environment and purpose of use.
Polarised lenses offer an effective solution for reducing glare and improving visual clarity in sunny environments, bringing comfort and protection to the eyes.
When considering polarised lenses, consult an eye care professional for guidance on the best option for your needs and lifestyle.
Photochromic Lenses
Photochromic lenses, also known as photosensitive lenses or photogray lenses, are a type of ophthalmic lens that has the ability to automatically adapt to changes in light. These lenses darken when exposed to ultraviolet (UV) light and return to a clear state when they are no longer exposed to this light. Here are some important aspects about photochromic lenses:
Photochromic lenses are designed to provide additional protection to the eyes against UV radiation. When exposed to sunlight, the lenses darken, reducing the amount of UV rays reaching the eyes. This helps minimise the risk of eye damage caused by excessive sun exposure.
Photochromic lenses have the ability to quickly adjust to changes in light. They darken for more comfortable vision in sunny outdoor environments, protecting the eyes from intense light. Indoors or at night, the lenses return to a clear state, allowing natural, unobstructed vision.
Photochromic lenses eliminate the need to constantly switch between sunglasses and prescription glasses. They are a practical option for people who frequently move from indoors to outdoors, allowing comfortable vision and adequate protection in environments with different light levels.
Photochromic lenses are available in different materials, designs and colours. This allows users to customise their lenses according to their aesthetic preferences and visual needs.
It’s important to remember that photochromic lenses may not darken completely indoors and may not darken as much in vehicles, as car windshields block part of the UV rays. In addition, the response time of lenses can vary according to the temperature, light intensity and duration of exposure to UV rays.
Photochromic lenses offer a practical and convenient solution for people who want UV protection and prescription in a single pair of glasses.
When considering this type of lens, it is important to consult an eye care professional to assess compatibility with your prescription and individual needs.
