Whether you are going for your first eye exam or you are a regular at it, you are all aware that an eye exam is a critical step towards attaining good health. Eye doctors have to perform various tests on your eyes, and if they suspect a serious problem, they will definitely recommend you to undergo surgery. This article tries to help you choose the best high index lenses according to eye doctors and their benefits. In addition, it offers tips on how to avoid problems that high indices can cause.
When you go for an eye exam, your doctor will ask about your daily routine and whether you wear contacts or glasses. He or she will also take note of the type of lenses that are currently in use. In most cases, if a lens is considered a “high” index (meaning it has a low refractive power), it can actually cause more errors than those with a lower index number.
Here are some factors to consider before choosing the best high index lenses, according to eye doctors:
No matter what your vision correction needs or budget is, you need to pick a lens that fits comfortably. Change the way it feels in your eyes by trying different glasses from one place and then another if there are multiple options available for purchase. It does not indicate anything about its quality just yet.
Go for premium models even when cheap ones can be bought online as they will last longer and offer better vision.
After you have chosen the best high index lenses for your eyes, it is essential to follow a few tips to avoid any potential problems:
1. Always choose quality lenses from a reputable manufacturer of high index lenses. Cheap models can often be counterfeited or copied and are not as effective as their pricier counterparts.
2. Exercise caution when using contact lens after-care products that contain alcohol or other chemicals; these can damage your lenses over time.
3. Be sure to get your eyes checked regularly, especially if you are using high index lenses. If there is any sign of lens wearing or damage, contact your doctor immediately for a corrective action plan.
4. Keep your lenses clean by rinsing them with warm water and mild soap after every use, as well as before putting them in the storage case.
5. Never sleep with lenses in; they can become more susceptible to damage if they are left in during the night.
6. If you experience any problems while wearing your lenses, seek medical attention immediately and follow the doctor’s advice to ensure proper vision care in the long term.
7. Finally, enjoy wearing your new glasses and look forward to seeing the benefits of improved vision!
Types of High-Index Lenses
There are a few different types of high-index lenses available on the market. They can be classified either by their degree of curvature (in which case they would be called “curved” or “concave”) or by their diameter (in which case they would be called “round”).
Curved lenses: These lenses have a gentle curve towards the eye, making them ideal for people with astigmatism. They are used for prescriptions as much higher than -10.00 so that the off-axis zone is adequately matched with the center of vision. Low-index lenses are rarely fitted to patients who have mild or moderate myopia; their low cost does not justify this expense by most optometrists (although there are some exceptions).
Concave lenses: These come in various thicknesses and levels of curvature, from very straight to virtually round. They are generally used to correct myopia up to +6.00 and often provide the best vision at distances greater than 12 feet (3 m).
Round lenses: These lenses are available in various diameters, from very thin (0.50 mm) to quite thick (4mm). They have a more natural appearance than the other lenses since they do not have curves. Round lenses are the most popular type of lens, as they provide good all-around vision.
